Run the following git command to download it to your system: $ git clone Source FilesĪ small C++ sample project has been setup on GitHub to accompany this tutorial. Upon completing this tutorial, you will have built up enough knowledge to be able to configure the compiler to your exact specifications for building a project with CMake.
CMAKE FLAGS HOW TO
Selecting a Compiler and Inspecting its Properties We then look at how to select another C++ compiler on the system to build our project, as well as outputting properties such as its path, ID and version.These settings are then used to compile the sample project included with this tutorial. Inspecting the Default Compiler This section details how to find out which compiler and compiler flags CMake uses on your system by default.We will progress in incremental steps as described below:

This tutorial details how to inspect, configure and output a project’s compiler settings using CMake. It is also possible to configure the compilation process based on the host system’s environment in a granular way. If not set, the Trilinos package, teuchos, will be build during the Dakota build.The CMake program makes it possible to write simple configuration files to control a project’s compilation process and generate native build files across platforms.
CMAKE FLAGS INSTALL
You will need to set the following variable if you want have a custom Trilinos install location. set(BOOST_ROOTĬACHE PATH "Use non-standard Boost install" FORCE)ĬACHE BOOL "Supress search paths other than BOOST_ROOT" FORCE) Set Trilinos path for Custom Trilinos Installation You will need to set the following variables iff CMake cannot find your installed version of Boost or if you have a custom Boost install location. set( DAKOTA_HAVE_MPI ONĬACHE BOOL "Build with MPI enabled" FORCE)ĬACHE FILEPATH "Use MPI compiler wrapper" FORCE) Set Boost path

Recommended practice is to set DAKOTA_HAVE_MPI and set MPI_CXX_COMPILER to a compiler wrapper. xxe4.2 set( CMAKE_C_FLAGS "$ & amp amp amp lt flag& amp amp amp gt "ĬACHE STRING "Fortran Flags for my platform" ) Set MPI options Uncomment and replace with actual compiler flag, e.g. Edit variables as needed.ĬMake Variables Set BLAS, LAPACK library paths ONLY if in non-standard locations set( BLAS_LIBS "/usr/lib64"ĬACHE FILEPATH "Use non-standard BLAS library path" FORCE )ĬACHE FILEPATH "Use non-standard BLAS library path" FORCE ) Set additional compiler options. Uncomment CMake variables below ONLY for values you need to change for your platform.Copy dakota-src/cmake/BuildDakotaTemplate.cmake into build directory.
