c++ - How to set up basic openMP project in CLion -
this question has answer here:
i trying run simple openmp program in clion ide. when run error:
cmakefiles\openmp_test_clion.dir/objects.a(main.cpp.obj): in function `main': d:/.../openmp_test_clion/main.cpp:9: undefined reference 'omp_get_thread_num' collect2.exe: error: ld returned 1 exit status here code:
#include <stdio.h> #include <omp.h> int main() { int id; #pragma omp parallel private(id) { id = omp_get_thread_num(); printf("%d: hello world!\n", id); } return 0; } here cmakelists.txt:
cmake_minimum_required(version 3.6) project(openmp_test_clion) set(cmake_cxx_flags "${cmake_cxx_flags} -std=c++11") set(source_files main.cpp) add_executable(openmp_test_clion ${source_files}) message(status "checking openmp") find_package(openmp) if(openmp_found) message("found openmp!) # add flags openmp set(cmake_c_flags "${cmake_c_flags} ${openmp_c_flags}") set(cmake_cxx_flags "${cmake_cxx_flags} ${openmp_cxx_flags}") set(cmake_shared_linker_flags "${cmake_shared_linker_flags} ${openmp_shared_linker_flags}") set(cmake_exe_linker_flags "${cmake_exe_linker_flags} ${openmp_exe_linker_flags}") else() message("missed openmp!") endif() here screen of toolchains: 
i have 0 experience openmp , beginner programmer in c++ please give me bit of explanation how setup project.
so after while figured out. changed cmakelists.txt following:
cmake_minimum_required(version 3.6) project(openmp_test_clion) # added -fopenmp set(cmake_cxx_flags "${cmake_cxx_flags} -std=c++11 -fopenmp") set(source_files main.cpp) add_executable(openmp_test_clion ${source_files}) and needed install openmp via tdm-gcc installer .
