make[2]: *** [slam/ndt_omp/CMakeFiles/ndt_omp.dir/src/pclomp/voxel_grid_covariance_omp.cpp.o] Error 1

I modify CMakeLists.txt with:
add_definitions(-std=c++11)
set(CMAKE_CXX_FLAGS "-std=c++11")
still have error:
catkin_ws/src/slam/ndt_omp/include/pclomp/gicp_omp_impl.hpp:78:61: error: ‘omp_get_thread_num’ was not declared in this scope
auto& nn_indecies = nn_indecies_array[omp_get_thread_num()];

It seems it failed to find OpenMP. Can you check if OpenMP has been installed in your environment?

I slove this problem. OpenMP has been installed ,but need to modify CMAKE_CXX_FLAGS "-std=c++11 -fopenmp" in cmakelist.
