Can I skip cmake compiler tests or avoid "error: unrecognized option '-rdynamic'"

Question

compilation options for cmake (on windows) for ARM target system but when I run configure it's starting compiler tests:

CMake Error at D:/Program Files/CMake 2.8/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:52 (MESSAGE):   The C compiler "D:/Program Files/yagarto/bin/arm-none-eabi-gcc.exe" is not   able to compile a simple test program.    It fails with the following output:     Change Dir: D:/merge/complex/build/CMakeFiles/CMakeTmp      Run Build Command:D:/PROGRA~1/YAGART~1/bin/make.exe "cmTryCompileExec/fast"    D:/PROGRA~1/YAGART~1/bin/make.exe -f   CMakeFiles/cmTryCompileExec.dir/build.make   CMakeFiles/cmTryCompileExec.dir/build    make.exe[1]: Entering directory   `D:/merge/complex/build/CMakeFiles/CMakeTmp'    "D:/Program Files/CMake 2.8/bin/cmake.exe" -E cmake_progress_report   D:/merge/complex/build/CMakeFiles/CMakeTmp/CMakeFiles 1    Building C object CMakeFiles/cmTryCompileExec.dir/testCCompiler.c.o    "D:/Program Files/yagarto/bin/arm-none-eabi-gcc.exe" -o   CMakeFiles/cmTryCompileExec.dir/testCCompiler.c.o -c   D:/merge/complex/build/CMakeFiles/CMakeTmp/testCCompiler.c    Linking C executable cmTryCompileExec    "D:/Program Files/yagarto/bin/arm-none-eabi-gcc.exe"   "CMakeFiles/cmTryCompileExec.dir/testCCompiler.c.o" -o cmTryCompileExec   -rdynamic     arm-none-eabi-gcc.exe: error: unrecognized option '-rdynamic'    make.exe[1]: *** [cmTryCompileExec] Error 1 

Using Yagatdo 4.6.* cross-compilation toolchain

How can I skip this tests or fix -rdynamic error that I am getting?

Answer 1

You can set CMAKE_<LANG>_COMPILER_WORKS to true to suppress further compiler checks for that language.

set(CMAKE_C_COMPILER_WORKS 1) 

Answer 2

You can skip the compiler checks by adding NONE to your project call:

project(<projectname> NONE) 

but this can have pretty far-reaching effects. For full details, run

cmake --help-command project 

I'm not familiar with ARM, so this is probably not your best option here. I guess you'd be better to see if there's a way to fix the -rdynamic flag.

EDIT:

It looks like this was identified as a bug which is effectively still unresolved. The comments in the bug report mention adding the following lines as a workaround (presumably before your project call):

set(CMAKE_SHARED_LIBRARY_LINK_C_FLAGS "") set(CMAKE_SHARED_LIBRARY_LINK_CXX_FLAGS "")
