Compatibility

In general, object code and modules compiled with earlier versions of Intel Fortran Compiler for Linux* (8.0 and later) may be used in a build with version 19.1. Exceptions include:

  • Sources that use the CLASS keyword to declare polymorphic variables and which were built with a compiler version earlier than 12.0 must be recompiled.
  • Objects built with the multi-file interprocedural optimization (-ipo) option must be recompiled with the current version.
  • Objects that use the REAL(16), REAL*16, COMPLEX(16) or COMPLEX*32 datatypes and which were compiled with versions earlier than 12.0 must be recompiled.
  • Objects built for the Intel® 64 architecture with a compiler version earlier than 10.0 and that have module variables must be recompiled. If non-Fortran sources reference these variables, the external names may need to be changed to remove an incorrect leading underscore.
  • Modules that specified an ATTRIBUTES ALIGN directive outside of a derived type and were compiled with versions earlier than 11.0 must be recompiled. The compiler will notify you if this issue is encountered.
  • Modules that specified an ATTRIBUTES ALIGN directive inside a derived type declaration cannot be used by compilers older than 13.0.1.
  • The implementation of the Fortran 2008 submodules feature required extensive changes to the internal format of binary .mod files. Therefore module files created by the version 16.0 or newer Fortran compiler cannot be used with version 15.0 or older Fortran compilers.
  • Objects built with Intel Fortran Compiler version 18.0 and earlier version of regcall calling convention must be recompiled with 19.0 or newer. Intel library libirng uses regcall. Version of this library shipped with 19.0 compiler version or newer is not compatible with older versions. regcall is implicitly used by following attribute:
    !DIR$ ATTRIBUTES [att,] VECTOR [:clause] [, att]... :: routine-name

Stack Alignment Change for REAL(16) and COMPLEX(16) Datatypes

In versions prior to 12.0, when a REAL(16) or COMPLEX(16) (REAL*16 or COMPLEX*32) item was passed by value, the stack address was aligned at 4 bytes. For improved performance, the version 12 and later compilers align such items at 16 bytes and expects received arguments to be aligned on 16-byte boundaries. This change is also compatible with gcc.

This change primarily affects compiler-generated calls to library routines that do computations on REAL(16) values, including intrinsics. If you have code compiled with earlier versions and link it with the version 12 libraries, or have an application linked to the shared version of the Intel run-time libraries, it may give incorrect results.

In order to avoid errors, you must recompile all Fortran sources that use the REAL(16) and COMPLEX(16) datatypes if they were compiled by compiler versions earlier than 12.0.

New and Changed Compiler Features

New features from Fortran 2018

  • Enhancements to the IMPLICIT statement allow specifying that all external procedures must declared EXTERNAL
  • Enhancements to the GENERIC statement permit it to be used to declare generic interfaces
  • The locality of variables may now be specified on a DO CONCURRENT statement

  • The exponent width e in a data edit descriptor may now be zero, analogous to a field width of zero
  • The RN edit descriptor now rounds to nearest as specified by Fortran 2018 and ISO/IEC/IEEE 60559:2011
  • The EX edit descriptor allows for hexadecimal format output of floating point values. Hexadecimal format floating point values are allowed on input.
  • SIZE= may be specified for non-advancing I/O
  • The values for SIZE= and POS= in an INQUIRE statement for pending asynchronous operations have been standardized
  • The value assigned to the RECL= specifier in an INQUIRE statement now has standardized values
  • A new form of the intrinsic function CMPLX does not require the KIND= keyword if the first argument is type COMPLEX
  • The arguments to the SIGN function may be of different kinds
  • INTEGER and LOGICAL arguments to intrinsic procedures are no longer required to be of default kind
  • The named constants STAT_FAILED_IMAGE and STAT_UNLOCKED_FAILED_IMAGE have been defined in the intrinsic
    ISO_FORTRAN_ENV module
  • The non-block DO statement and the arithmetic IF statement are now deleted in Fortran 2018. Intel® Fortran fully supports features deleted in the FORTRAN standard
  • COMMON, EQUIVALENCE and BLOCKDATA statements are now obsolescent
  • The labeled form of DO loops is now obsolescent
  • Locality of variables in DO CONCURRENT constructs can now be declared on the DO CONCURRENT statement
  • Specific names of intrinsic procedures are now obsolescent
  • FAIL IMAGE statement allows debugging recovery code for failed images without having to wait for an actual image failure
  • The named constants STAT_FAILED_IMAGE and STAT_UNLOCKED_FAILED_IMAGE have been defined in the intrinsic
    ISO_FORTRAN_ENV module
  • An optional argument STAT= has been added to ATOMIC_REF and ATOMIC_DEFINE intrinsic procedures
  • Optional STAT= and ERRMSG= specifiers have been added to the MOVE_ALLOC intrinsic procedure, to image selectors, and to the CRITICAL statement and construct
  • Atomic subroutines ATOMIC_ADD, ATOMIC_AND, ATOMIC_CAS, ATOMIC_FETCH_ADD, ATOMIC_FETCH_AND, ATOMIC_FETCH_OR, ATOMIC_FETCH_XOR, ATOMIC_OR, and ATOMIC_XOR have been implemented
  • Collective subroutines CO_BROADCAST, CO_MAX, CO_MIN, CO_REDUCE, and CO_SUM have been implemented
  • The SELECT RANK construct has been implemented allowing manipulation of assumed rank dummy arguments
  • The compiler will now diagnose the use of nonstandard intrinsic procedures and modules as required by Fortran 2018
  • Transformational intrinsic functions from the intrinsic modules ISO_C_BINDING, IEEE_ARITHMETIC, and IEEE_EXCEPTIONS are now allowed in specification expressions
  • You can now specify the optional argument RADIX for the IEEE_GET_ROUNDING_MODE and IEEE_SET_ROUNDING_MODE intrinsic module procedures
  • The optional ROUND argument has been added to the IEEE_RINT function in the intrinsic module IEEE_ARITHMETIC
  • The intrinsic module IEEE_ARITHMETIC now includes the functions IEEE_FMA, IEEE_SIGN_BIT, IEEE_NEXT_UP and IEEE_NEXT_DOWN
  • The intrinsic module procedures IEEE_MAX, IEEE_MIN, IEEE_MAX_MAG, and IEEE_MIN_MAG have been implemented
  • The intrinsic module procedures IEEE_INT and IEEE_REAL have been implemented
  • The intrinsic module IEEE_EXCEPTIONS now contains a new derived type, IEEE_MODES_TYPE, which can be used to save and restore the IEEE_MODES using the IEEE_GET_MODES and the IEEE_SET_MODES intrinsic module procedures
  • A new rounding mode, IEEE_AWAY has been added
  • SUBNORMAL is now synonymous with DENORMAL
  • IEEE_QUIET_EQ, IEEE_QUIET_NE, IEEE_QUIET_LT, IEEE_QUIET_LE, IEEE_QUIET_GT, IEEE_QUIET_GE, IEEE_SIGNALING_EQ, IEEE_SIGNALING_NE, IEEE_SIGNALING_GT, IEEE_SIGNALING_GE, IEEE_SIGNALING_LT, and IEEE_SIGNALING_LE intrinsic module procedures have been implemented

New features from OpenMP 5.0*

  • IF clause on SIMD directive
  • NONTEMPORAL clause on SIMD directive
  • Inclusive/exclusive scan operations in SIMD and TARGET SIMD constructs.

Changed compiler behavior

  • Previous compiler versions erroneously permitted a PRIVATE or SEQUENCE statement to appear prior to the declaration of any type parameters in a derived type declaration. Intel® Fortran Compiler 19.1 no longer permits this behavior.
  • The INQUIRE statement now uses realpath’/’GetFullPathNameA’ and uses the resulting canonicallized file-paths if the calls succeeds. An example of the change is:
    Open file as “bar/foo”.
    Before:
    Inquire whether “./bar/foo”, “bar//foo” or “bar/../bar/foo” is open – it is not.
    After:
    Inquire whether “./bar/foo”, “bar//foo” or “bar/../bar/foo” is open – it is.
  • In 19.0 compiler version, all procedures with the exception of C_F_POINTER from the intrinsic module ISO_C_BINDING were made PURE per the Fortran 2018 standard. Interpretation 18/007 declared that making C_F_PROCPOINTER PURE was a mistake. 19.1 complies with this interpretation and makes C_F_PROCPOINTER IMPURE.

New and Changed Compiler Options

Please refer to the compiler documentation for details. Following new compiler options added:

For a list of deprecated compiler options, see the Compiler Options section of the documentation.

-assume [no]old_inquire_recl

Determines the value of the RECL= specifier on an INQUIRE statement for an unconnected unit or a unit connected for stream access.

-assume [no]old_ldout_zero

Determines the format of a floating-point zero produced by list-directed output. old_ldout_zero uses exponential format, no_old_ldout_zero uses fractional format.

-check [no]udio_iostat

Determines whether standard conformance checking occurs when user defined derived type input/output procedures are executed.-m[no-]branches-within-32B-boundaries

Determines whether warnings occur for any dummy procedures or procedure calls that have on explicit interface or have not been declared EXTERNAL.

-m[no-]branches-within-32B-boundaries

This option is supported in versions 19.0 update 8 of the compiler and above. The details about this option can be found in the Intel® Fortran Compiler 19.1 Developer Guide and Reference. To find more information, see https://www.intel.com/content/dam/support/us/en/documents/processors/mitigations-jump-conditional-code-erratum.pdf

Support Deprecated

The compiler option -stand f15 will be removed in next update. Use -stand f18 instead.

GNU* DBG support will be removed in the next update.

Support Removed

Loop Profiler

The Loop Profiler feature is removed in Intel® Fortran Compiler 19.1. The following compiler options related to Loop Profiler are removed: -profile-loops=keyword, -profile-loops-report=value -profile-functions, -guide-profile.

32-bit applications are no longer supported

Starting with the 19.0 release of the Intel® Fortran Compiler, macOS 32-bit applications are no longer supported.
If you want to compile 32-bit applications, you should use an earlier version of the compiler and Xcode* 9.4 or earlier.

Fortran Integration into Xcode removed

Xcode integration capabilities within our Fortran Compiler bundle have been removed. Command line interface remains fully functional for macOS.

Keep in mind that installation of Xcode is still recommended, as command line tools from Xcode are required by the command line compiler. However, you can install just the Xcode Command Line Tools with this command from a terminal window:

Known Limitations

Slow License Checkout macOS 10.15

The license checkout performance on macOS Catalina 10.15 is roughly 1.1 seconds per source file. This is a 10x slowdown on this OS compared to previous versions of macOS. We are evaluating our license technology for a solution but at this time we have not root caused the issue. If this slowdown is an issue, please revert back to the previous macOS 10.14 where this slowdown does not occur.

Error 'no rule to process file' within Xcode* 10 and 11

macOS*’s XCode 10 and 11 come with a new build system and it is configured as the default. Currently, the Intel Fortran Compiler does not support it. You will see the error 'no rule to process file' when building an Intel Fortran Compiler project within XCode. Please switch to “Legacy Build System” in Project Settings to build your Fortran project in Xcode.

For more details please find this article.

Keep in mind, support for Xcode Integration is deprecated and will be removed in a future update - SEE THIS NOTE

Fortran 2008 and Fortran 2018 Feature Summary

The Intel® Fortran Compiler supports full Fortran 2008 standard and most features from the Fortran 2018 standard. New Fortran 2018 features supported by the current version are listed in the 'New features from Fortran 2018' section.

Please refer to the Fortran 2008 Standard (PDF) and the Fortran 2018 Standard (PDF) if necessary.

IMPORTANT: This page has only historical value. It does NOT apply to current R versions. See this page for current information.

NOTE: some links may be broken - older binaries have been lost in an incident.

Mandatory tools

In order to compile R for Mac OS X 10.4 or higher, you will need the following tools: (for Mac OS X 10.5 and higher look further down)
  • Xcode Development Tools 2.4.0 (or higher) from Apple
    They can be obtained from Apple's Xcode pages. Also, all recent Mac OS X versions come bundled with Xcode Tools, they are located on the installation DVD. However, if your OS X came with Xcode older than version 2.4.0, you will have to download a more recent version from the above site.

    Note: The binary Leopard build of R on CRAN requires Xcode 3.1 or higher

  • GNU Fortran compiler
    Unfortunately Xcode doesn't contain a Fortran compiler, therefore you will have to install one. For convenience we provide a binary of the GNU Fortran compiler, because most other binaries are either incomplete or broken (do not use compilers from HPC, they won't work correctly!). You can download it from CRAN or here:
    gfortran-4.2.3.dmg (ca. 27MB, GNU Fortran 4.2.3 release)
    MD5 hash: 9551fc46f55537dd1db581154daf27ef

    This binary contains gfortran 4.2.3 (release) for both Intel and PowerPC Macs. It supports all four targets (i386, ppc, x86_64 and ppc64) and features Apple's Darwin compiler drivers, i.e. you can build fat binaries with one command (e.g. gfortran -arch i386 -arch ppc -o tf tf.f).

    Make sure you add /usr/local/bin to your PATH in order to use this compiler. This can be done, e.g. by
    export PATH=$PATH:/usr/local/bin

    Note: If you are interested in cutting-edge compilers and/or integration of GNU Fortran and Apple's compilers see gcc 4.2 section below. That section is also the right place to go if you use the binary Leopard build of R.

    Previous versions:
    gfortran-4.2.1.dmg (ca. 28MB, 4.2.1 release, also avaiable in R 2.6.0)
    gfortran-4.2.0.dmg (ca. 28MB, 4.2.0 release, also avaiable in R 2.5.1)
    gfortran-4.2.0-20070325.dmg (ca. 16MB, 4.2.0 2007/03/25 pre-release without cc back-end)

Mandatory Tools - Leopard CRAN build

R build can be built with the above requirements, but if you want to use source compilation with the CRAN build of R for Mac OS X 10.5 or higher (aka Leopard build), you will need more recent tools:
  • Xcode Development Tools 3.1 (or higher) from Apple with gcc-4.2
    They can be obtained from Apple's Xcode pages. Make sure gcc-4.2 is selected during the installation (default in recent Xcode versions).
  • GNU Fortran compiler
    Do not install Fortran compilers that comde with Tiger builds of R. Remove them using sudo gfortran-uninstall if you installed them before (unless you want to use both builds in parallel). Then install gfortran-4.2 addition to Apple compilers (see below - you have to pick the one that maches your Xcode version!). Although the Tiger compilers supplied with the Tiger build of R can be used, they will result in slightly different binaries.

Optional tools and libraries

The following tools and libraries are optional. R can be compiled without them, but they provide additional capabilities to R.
  • LaTeX
    In order to produce documentation, LaTeX is necessary. It can be obtained from several places, for example as a part of MacTeX.
  • GNU readline
    Although Mac OS X comes with readline-replacement library, it lack some functionality like backward search etc. Therefore many user prefer GNU readline. Binary for all four architectures is provided from CRAN as a part of the devpack: Tools on CRAN or see libs on this site for more recent versions.
  • PNG and JPEG libraries
    If bitmap manipulation libraries are present, R will add graphics device support for those bitmap formats. There are also other package that take advantage of PNG and JPEG, so it is in general a good idea to install them.Again, they are now part of the devpack on CRAN: Tools on CRAN or more recent versions are available from libs.
  • cairo
    R 2.7.0 comes with cairo support. The following tar-ball contains cairo and its dependencies (FreeType, pkgconfig and png) in static form such that you can compile R the same way it is compiled for CRAN:Tools on CRAN

Apple Xcode gcc-42 add-ons

Download Intel Fortran Compiler 2016

  • GNU Fortran 4.2.4 for Mac OS X 10.7 (Lion):
    Download: gfortran-lion-5666-3.pkg (for Xcode 4.1)
    This package adds GNU Fortran to Xcode 4.1 for Lion (Apple's gcc 4.2 build 5666.3). Requires Mac OS X 10.7 (Lion) and Xcode 4.1.

    gcc-4.2 (Apple build 5666.3) with GNU Fortran 4.2.4 for Mac OS X 10.7 (Lion):
    Download: gcc-42-5666.3-darwin11.pkg (for Xcode 4.2 and higher)
    This package contains gcc-4.2 (Apple build 5666.3) including GNU Fortran for Mac OS X 10.7 (Lion). It is needed for Xcode 4.2 or higher since Apple has dropped gcc-4.2 from Xcode. It works with Xcode 4.0 and 4.1 as well, but there you can use the above smaller Fortran package instead.

  • GNU Fortran 4.2.4 for Mac OS X 10.6 (Snow Leopard):
    Download: gfortran-42-5664.pkg (for Xcode 3.2.3 through 3.2.5)
    This package adds GNU Fortran to Xcode 3.2.3/4/5 for Snow Leopard (Apple's gcc 4.2 build 5664). Requires Mac OS X 10.6 (Snow Leopard) and Xcode 3.2.3, 3.2.4 or 3.2.5 (it will also work with more recent Xcode such as 4.0 or 4.1 on Snow Leopard since Apple stopped updating gcc)
    Download: gfortran-42-5659.pkg (for Xcode 3.2.2)
    This package adds GNU Fortran to Xcode 3.2.2 for Snow Leopard (Apple's gcc 4.2 build 5659). Requires Mac OS X 10.6 (Snow Leopard) and Xcode 3.2.2.
    Download: gfortran-42-5646.pkg (for Xcode 3.2 and 3.2.1)

    Dynamic libgfortran: libgfortran-4.2.4-5646.tar.gz (NOT needed for R)
    The compiler above contains static libgfortran. To avoid library pollution the dynamic gfortran library is not included since it is not necessary for most projects and causes problems for people that don't have it installed at run-time. If you know what you're doing, you can install it, but be aware that your FORTRAN binaries will depend on it and OS X does NOT include it.
    Install: sudo tar fxz libgfortran-4.2.4-5646.tar.gz -C /

  • GNU Fortran 4.2.4 for Mac OS X 10.5 (Leopard):
    Download: gfortran-42-5577.pkg (for Xcode 3.1.4 only!)
    This package adds GNU Fortran 4.2.4 to Apple's Xcode 3.1.4 gcc 4.2 (build 5577) compilers on Mac OS X 10.5 (Leopard). It does NOT work on Snow Leopard. This binary has been built the Apple way with the gcc_42 (build 5577) sources (by adding the Fortran directories from gcc 4.2.4 release), so it features full Apple driver (i.e. all special flags work) and works directly with the gcc 4.2 system compiler. You have to install Xcode 3.1.4 first (from ADC).

    Older versions:

    This is a set of Apple's gcc 4.2.1 (build 5531) compilers for Mac OS X 10.4 (Tiger). Xcode 2.5 has gcc 4.0 only, and gcc 4.2 update is currently available only for Leopard, so this binary fills the gap.
    The second file contains the Fortran compiler which is not part of the Apple sources, but was compiled along with the Apple sources.

Building a universal compiler

Note: This section is now becoming obsolete given Apple's gcc 42 branch, but it is kept here until we have more definite information on Apple's Fortran support. If you're interested in compiling Apple's gcc-4.2 branch with Fortran support, add Fortran sources and use this patch: gfortran-5564.diff (for gcc-4.2 Apple build 5564/5566/5577 and GNU Fortran 4.2.4) or gfortran-5531.diff (for gcc-4.2 Apple builds 5531 or 5553 and GNU Fortran 4.2.3). Complete sources are also in /src.

Apple provides universal compilers in their Xcode tools. This means that the compiler itself can be run on both on Intel and PowerPC Macs natively. In addition, Apple's compilers can produce binaries for any of the architectures i386, ppc, x86_64 and ppc64. This mean that the same compiler suite is usable on any Mac and can target any Mac as well.

Apple also provides a special driver for all compilers such that they support additional flags such as -arch which allow us to build fat binaries in one run. Internally the driver invokes multple separate compilers, one for each distincts -arch flag and combines the result using lipo. This is highly convenient and allows for compilation of the form:
gcc -c foo.c -arch ppc -arch i386 -arch ppc64 -arch x86_64
which produces one fat object file (foo.o) containing binaries for all four architectures.

Unfortunately Apple's branch of gcc is based on a fairly old version of gcc and they don't support Fortran. (Update: 2007/11 there is some hope, Apple's gcc-42 branch can be used to compile Fortran - see binaries above - and Apple is allegedly working on an official Fortran release) Therefore it is sometimes necessary to compile gcc from the original FSF sources. However, such compilers (e.g. as provided by HPC) are very limited, because they work only on one kind of Mac (Intel or PPC) and don't support cross-compiling. Therefore is it necessary to merge Apple's approach and FSF gcc sources to create a more usable compiler for Mac OS X.

In this part I want to describe steps necessary to create such universal compiler from any gcc sources. The whole process is fully automated by a shell script which can be obtained here (it must be run sudo unless you have write-premissions in /usr/local). I have used this procedure to create the Fortran compiler available above. Run the script with '-h' flag to see all the options.

How does it work?

Conceptually Apple's drivers use naming scheme to distinguish compilers for Intel and PowerPC targets. In the Xcode installation they are called powerpc-apple-darwin8-gcc-4.0.1 and i686-apple-darwin8-gcc-4.0.1. The virtual targets ppc64 and Fortranx86_64 are compiled by adding -m64 flags to the corresponding compiler. The driver (gcc-4.0) invokes the actual compiler(s) that are needed and uses lipo to create the resulting fat object/binary.

In order to build an universal compiler suite, we need to proceed using these steps:

  • get cross-compilation tools
    The building process requires tools for cross-compilation to be of the form <arch>-apple-darwin8-<tool>. However, Apple's tools expect the -arch flag instead of naming conventions. Therefore it is necessary to create small stubs that map FSF naming conventions into corresponding invocations of the Apple tools. Such stubs are automatically generated by Apple's gcc bulding process, but they are also available in this file: gcc-bin-stubs.tar.gz
  • get gcc sources
    This is obviuos, you clearly need gcc sources. One way to get them is via svn, for example:
    svn co svn://gcc.gnu.org/svn/gcc/branches/gcc-4_2-branch gcc-4.2
  • compile and install the native compilers
    The compilation part is straight-forward, just configure and build gcc for the i686-apple-darwin8 host and powerpc-apple-darwin8 host. The harder part is the installation, because Apple uses fat files, whereas FSF's multilibs relies on different names. First install one architecture, rename the binaries according to Apple's compiler name conventions and move everything in /usr/local/lib aside. Then install the other architecture and do the same. Finally combine all system libraries using lipo into /usr/local/lib. This applies also to 64-bit architectures which should also be included in the libraries placed in /usr/local/lib. Then get all the other files and symlinks back. Finally remove everything from the subdirectories in lib and replace it with symlinks. This should give you a working environment for all four targets. Finally adjust the IDs of the libraries to match their location.
  • compile and merge cross-compilers
    With the above compiler we cannot create universal binaries, because the cross-compilers are missing. We need to compile them now. Note that we don't need libraries anymore, because they are already in place, so even if some of the libraries fail when cross-compiled, we don't care. The cross-compilers don't even need to be installed, just lipo the binaries of the cross-compilers into /usr/local/libexec/gcc/*-apple-darwin*/* and the drivers into /usr/local/bin with the corresponding name. You may want to strip them as well in order to reduce size.
  • get and install the Darwin driver
    The driver is part of Apple's gcc and can be obtained correspondingly. I have packaged the minimal sources and the corresponding Makefile into one small tar-ball which is available here: gcc-darwin-driver.tar.gz. It is based on gcc-5363 sources released by Apple, but the Makefile allows the use of any Apple's gcc sources - just set AGCC accordingly. Move the resulting driver files into /usr/local/bin and you're all set!
Was this too compilcated? Well, use the script above or just fetch the binaries which are provided in the form of a convenient Apple installer above.(sources for open source software not linked directly)
