Brew Gcc
The gcc from homebrew should reside in /usr/local/bin and when that is listed before the Xcode version of gcc / clang, you’re done - the local compilers will be called unless a package is hard coded to the full path of a different compiler than the one you have in /usr/local. We'll be installing GCC 4.8.1 and GDB through a tool called Homebrew. If you want an additional guide on all of the following steps (except for installing GCC), the one by Moncef Belyamani is quite helpful. When you follow it, ignore anything about installing Ruby; that is, stop after setting up git.
There are two C++ standard libraries supported by Apple compilers.
The default for 10.9 and later is libc++, which is also the default for clang on olderplatforms when building C++11 code.
Homebrew can install its own current versions of glibc and gcc for older distributions of Linux. Features, installation instructions and requirements are described below. Terminology (e.g. The difference between a Cellar, Tap, Cask and so forth) is explained in the documentation. Installing the ARM Toolchain for Windows ¶. Download and run the installer to install arm-none-eabi-gcc and arm-none-eabi-gdb. Select the default destination folder: C:Program Files (x86)GNU Tools ARM Embedded8 2018-q4-major. Notes: Check the Add path to environment variable option before you click the Finish button for the installation. You may select a different folder but the. $ sudo brew install gcc@7 Password: Error: Running Homebrew as root is extremely dangerous and no longer supported. As Homebrew does not drop privileges on installation you would be giving all build scripts full access to your system. 所以还是按brew的建议sudo目录。 但是用gcc -v查gcc版本还是6.2，什么情况？.
The default for 10.8 and earlier was libstdc++, supported by Apple GCCcompilers, GNU GCC compilers, and clang. This was marked deprecated with awarning during compilation as of Xcode 8.
There are subtle incompatibilities between several of the C++ standard libraries,so Homebrew will refuse to install software if a dependency was built with anincompatible C++ library. It’s recommended that you install the dependency treeusing a compatible compiler.
If you’ve upgraded to 10.9 or later from an earlier version: Because the default C++standard library is now libc++, you may not be able to build software usingdependencies that you built on 10.8 or earlier. If you’re reading this page becauseyou were directed here by a build error, you can most likely fix the issue ifyou reinstall all the dependencies of the package you’re trying to build.
Example install using GCC 7:
Gcc is part of Xcode. You can download it from the App Store. Once it is installed and you start it, it will ask you to install command line tools. Once it is installed, you can open a terminal window and check if it has been installed:
which gcc
It should show: /usr/bin/gcc
Fortran is not available with Xcode... you have a few options:
1. Download the binaries from gcc.gnu.org:
MacOS
The gfortran maintainers offer nice Apple-style installers for:
macOS Sierra (10.12): download gfortran 6.3
OS X El Capitan (10.11): download gfortran 6.1
OS X Yosemite (10.10): download gfortran 5.2 or gfortran 4.9.2
OS X Mavericks (10.9): download gfortran 4.9.0 or gfortran 4.8.2
OS X Mountain Lion (10.8): download gfortran 4.8.2
OS X Lion (10.7): download gfortran 4.8.2
2. You can also install from other project packing software like macports or homebrew :
same webpage from above:
Other projects packaging GCC (and gfortran) binaries for Mac include:
- 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.
- via Homebrew
