Supported platforms. Ns-3 is primarily developed on GNU/Linux and macOS platforms, and the minimal requirements to run basic simulations are a C compiler; either g or clang compiler, and Python (version 3) interpreter.

For targets that produce DWARF debugging information GCC now defaults to DWARF version 5 (with the exception of VxWorks and Darwin/Mac OS X which default to version 2 and AIX which defaults to version 4). This can produce up to 25% more compact debug information compared to earlier versions. Doing it Right¶. Xpilot x plane 11.50. Let’s install a real version of Python. Before installing Python, you’ll need to install GCC. GCC can be obtained by downloading Xcode, the smaller Command Line Tools (must have an Apple account) or the even smaller OSX-GCC-Installer package.

This page gathers links to all unofficial gfortran binary packages people regularly build, based on the current development gfortran source code.

Gcc Mac Os XGcc
  • Windows

  • MacOS

  • GNU/Linux

  • Build GNU Fortran from source

Note: There do not exist any official FSF/GNU/GCC binary builds (only source packages). Most of the builds below come from gfortran maintainers but not all.


If in doubt, or if you don't know what Cygwin and MinGW are, the package for you is the MinGW ('native Windows') package!

  • MinGW for Win64: The Mingw-w64 project has regularly updated snapshots of compilers generating 64-bit Windows executables. They provides several compilers, which run on Windows (32-bit and 64-bit Windows), Cygwin, Linux, and Darwin/MacOS - and which generate binaries for 32bit or 64bit Windows. The file name pattern is <target>-<host>-<option-version>-<date>; thus, mingw-w64-bin_x86_64-mingw_20100527.zip is a compiler targeting 64bit Windows (mingw-w64) but also running ('host') on 64bit Windows (xx86-64-mingw); you might search for the file in Toolchains targetting Win64 (Personal Builds or Automatized Builds).

  • MinGW build ('native Windows' build)

    • Official MinGW builds (only releases), last seen was 6.3.0 (2017-05-30)

    • The MinGW for Win64 project has also binaries for 32bit Windows; e.g. mingw-w32-bin_i686-mingw_<date>.zip runs on and generates binaries for 32bit Windows (cf. above); you might search for the file in Toolchains targetting Win32 (Personal Builds or Automatized Builds).

  • TDM GCC: MinGW/MinGW-W64 Builds

  • MinGW 32/64bit builds by www.Equation.com (builds were announced at comp.lang.fortran; note - equation.com is not affiliated with any MinGW or GCC developer. Use at your own risk)

  • Cygwin: The Cygwin project offers up-to-date builds of GCC and gfortran

  • Octave: Octave 6.1 comes with gcc/gfortran-9.3.1. From the Windows start menu, open up Octave and you will find the bash shell. Stick it to your task bar so it's always to hand. Combined with Notepad++ (https://notepad-plus-plus.org/), you will be able to get on with fortran development using nothing but GPL tools. Alternatively, the 'system' command can be used to run gfortran from the Octave GUI together with the Octave editor.


The gfortran maintainers offer nice Apple-style installers for macOS: https://github.com/fxcoudert/gfortran-for-macOS/releasesDetailed instructions can be found here.

Gcc Mac Os X

Other projects packaging GCC (and gfortran) binaries for Mac include:

  • Homebrew offers the latest stable gfortran release as part of the 'gcc' package.

  • HPC Mac OS X offers GCC builds, which include gfortran

  • MacPorts (package name, e.g., 'gcc48') - the fastest way to get a developer version of GCC. MacPorts comes with a packing software, but all software is compiled before installation. For the developer version, the 'Portfile' is updated approx. weekly.

  • Fink offers GCC packages (all released versions) - similar to MacPorts, but also offers binaries; it does not have the developer versions, just the releases.


Most Linux distributions offer gfortran packages, some have also builds for the experimental versions

Nightly builds are available at:

Gcc Download Mac Os X

  • 32-bit processors (i686)

    • Download from gfortran.com

    • Installation instructions

  • 64-bit AMD-compatible processors (x86_64, AMD64,Intel64, em64t)

    • Download from gfortran.com (README, nightly builds, 4.3 to 4.9 snapshots)

    • gcc-4.8-infrastructure package (GCC 4.8 and later; for GCC 4.3 to 4.7 use gcc-infrastructure), which contains required libraries (GMP, MPFR, MPC, etc.) - simply unpack in the 'gcc-trunk' (or 'gcc-4.6' or ..) directory

    • To unpack .xz files: Use xzcat with tar. It is contained in pre-build xz package, if you don't have it.

    • Needs to be updated: Installation instructions

Building from Source

See also InstallingGCC and http://gcc.gnu.org/install/

  1. Obtain the source code either via
    • subversion

    • git

    • Bazaar

    • unpacking a tarball

  2. You should have the right versions of GMP, MPFR and MPC (and optionally for Graphite: CLOOG and ISL) installed, which you can download from ftp://gcc.gnu.org/pub/gcc/infrastructure/ (They can also be automatically build with GCC.)

    • Note: You can use ./contrib/download_prerequisites to download them.

  3. Follow the instructions; in a nutshell, you will do

    • create a build directory, e.g. gcc-build underneath the source directory

    • go to the build directory and run configure from there; for instance: ./configure --prefix=$HOME/gcc-trunk --enable-languages=c,fortran

    • run make

    • run make install

Useful configure options: --enable-checking=release which disables some compile-time checks which slow down the compiler; --disable-bootstrap which speeds up the build but uses the system compiler and disables some consistency checks; --disable-build-poststage1-with-cxx (for 4.7 or higher) avoids building GCC with a C++ compiler, esp. useful if no C++ should be compiled; --disable-libstdcxx-pch speeds up the compilation a bit by not creating pre-compiled header files.
