Does someone setup OpenMP for Android/iOS (or desktop with cmake) and can give some advices, what to do, that it will run correct? My naiv way was (insert in the CMakeLists.txt):
find_package(OpenMP)
if (OPENMP_FOUND)
set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
set (CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}")
endif()
but it doesn’t compile in CLion:
Undefined symbols for architecture x86_64:
"___kmpc_critical", referenced from:
_.omp_outlined._debug__ in MyClass.cpp.o
"___kmpc_end_critical", referenced from:
_.omp_outlined._debug__ in MyClass.cpp.o
"___kmpc_fork_call", referenced from:
namespace::MyClass::func() in MyClass.cpp.o
"_omp_get_thread_num", referenced from:
_.omp_outlined._debug__ in MyClass.cpp.o
ld: symbol(s) not found for architecture x86_64
I want to use it for some calculations, so it can use multithreading the easy way.
PS: Maybe the cocos team can preconfigure it in v4 (or someone is willing to create a PR with it).
