I'm describing below what i've done, maybe someone highlightsĬmake. Specify flags of the form -DVAR:TYPE=VALUE to be passed to the cmake command-line used to drive the test build.I'm trying to compile out-of-source an embedded C application using CMakeĪnd MinGW and to use specific compiler flags for some source files. Obviously I did the wrong thing with CMAKE_FLAGS and misread: So, I can get it to do what I want (aka fail)…but only in a way that seems wrong to me. Gmake: Leaving directory '/home3/mathomp4/RomeTest/CMakeTest/build/test/CMakeFiles/CMakeTmp' Use this in combination with INTERFACE libraries and you can. nobackupp16/gmao_SIteam/cmake/cmake-3.17.1/bin/cmake -E cmake_link_script CMakeFiles/cmTC_f89a4.dir/link.txt -verbose=1 CMake has the ability to check whether compiler flags are supported. That file is compiled with CMAKECXXFALGSRELEASE (like other files.)

Where I “hijacked” COMPILE_DEFINITIONS and: COMPILE_RESULT_VAR = TRUEĬOMPILE_OUTPUT = Change Dir: /home3/mathomp4/RomeTest/CMakeTest/build/test/CMakeFiles/CMakeTmp So to test some things, I made up a simple CMake tester thinking this would be a way to test: cmake_minimum_required (VERSION 3.17) Our CMake files for this project have assume “If Intel Fortran, use this flag” but now I need to be more subtle.
These macros add flags to the following CMake variables. Regarding CMAKECXXFLAGS and CMAKECXXFLAGSRELEASE, is CMAKECXXFLAGS used if no build type is specified and CMAKECXXFLAGSRELEASE used if the build type is 'Release' If that is so, I plan to assign my desired release options to CMAKECXXFLAGSRELEASE and assign that variable to CMAKECXXFLAGS. Please verify that both the operating system and the processor support Intel(R) X87, CMOV, MMX, FXSAVE, SSE, SSE2, SSE3, SSSE3, SSE4_1, SSE4_2, MOVBE, POPCNT, AVX, F16C, FMA, BMI, LZCNT and AVX2 instructions.

In the previous episode we have learned how to configure and build: cmake -S. How to configure for a debug build or a release build.
CMAKE COMPILER FLAGS CODE
The issue is that I’m porting some code from Intel chips to AMD Rome chips and I’ve found that if I compile (using Intel Fortran) with -xCORE-AVX2, code will compile fine on the Rome chips, but not run: $ cat bobo.F90 How to see compile flags and definitions and how to control them. I’m trying to figure out how to test if a compiler flag runs on a processor.
