(Yes, I've run xcode-select -install multiple times the fact that I had to run it multiple times because of network glitches may be part of the trouble.) (I got GCC 7.2.0 to compile successfully on I don't recall what gymnastics - if any - were required to get this to work.) There's probably an easy fix I just haven't spent the time chasing it yet. The immediate error was a missing header I'll need to track down whether my XCode 9 installation is correct - or, more accurately, why it isn't correct since is a standard header in C++98 onwards. On, I failed to build GCC 7.2.0 on macOS High Sierra 10.13 (using XCode 9 for the bootstrap compiler) using the same script as worked on Sierra 10.12.

bz2), but since the standard Mac version of tar does that for me, it'll probably work for you too. Make sure your version of tar supports all 4 different compressed file formats (. This is the script I used for GCC 4.8.2: GCC_VER=gcc-4.8.2 Use a script to extract the source for GCC and the support libraries into a directory, create the object directory, and run the build. MPC Library version 0.8.1 (or later) from.MPFR Library version 2.4.2 (or later) from.GNU Multiple Precision Library (GMP) version 4.3.2 (or later) from.The instructions are in the gcc-4.x.y/INSTALL/index.html file in the GCC source code, or online at. Definitely, definitely, definitely, invoke make with -j8, or otherwise the build will take about 4 hours! (With -j8, it took 1 1/3 hours on my Mid-2012 MBP with 8gb RAM.) ( make -j8 means make can build 8 threads simultaneously (4 cores + HT), whereas on a 2-core machine you would run make -j4.)ĭownload the source for GCC and numerous supporting packages.Make sure you invoke configure with CC=clang CXX=clang++ so GCC knows it isn't being compiled by GCC.I recommend putting all your sources in the gcc directory, rather than building and installing separately (it's faster this way).

(XCode has some buggy headers, and while I didn't notice any issues building GCC I have had issues with other software (e.g. If possible, use the standalone Developer Tools, not XCode.Make sure you use ISL 0.12, not the latest version (0.14). Yes, they are optional, but they make a more optimised compiler and I had trouble building without them.

I would like to avoid modifying the code if at all possible.ĮDIT: Success! Using GCC 4.9.2 (with GMP 5.1.3, MPFR 3.1.2, MPC 1.0.2, ISL 0.12.2, and CLooG 0.18.1) I succesfully built GCC.

I need the existing GCC (hardlink to clang) to remain the default, but to easily be able to use GNU GCC when I need to.

I would like to use the latest GCC, compiled from source, if possible.

I don't want to use MacPorts, fink, homebrew or any other third party package manager.

I was wondering what the best way to install GNU GCC on OS X would be. I have recently become frustrated with the new clang compiler included with Xcode 5.
