CMake Cookbook

Compilers

We will need compilers for C++, C, and Fortran. These should be fairly recent, as we require support for recent language standards in most of the recipes. CMake offers very good support for many compilers, from both commercial and non-commercial vendors. To keep the recipes consistently cross-platform and as operating system independent as possible, we have worked with open source compilers:

• On GNU/Linux, the GNU Compiler Collection (GCC) is the obvious choice. It is free and available for all distributions. For example, on Ubuntu, you can install the compilers as follows:

$ sudo apt-get install g++ gcc gfortran 

• Clang, in the LLVM family, is also a good choice for C++ and C:

$ sudo apt-get install clang clang++ gfortran
