Error related to OpenMP_C

[XINS3]

When I implement the comment: cmake -DCMAKE_BUILD_TYPE=Release ..
It shows the error as follows:
CMake Error at /opt/homebrew/Cellar/cmake/3.30.3/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:233 (message):
Could NOT find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES)
Call Stack (most recent call first):
/opt/homebrew/Cellar/cmake/3.30.3/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:603 (_FPHSA_FAILURE_MESSAGE)
/opt/homebrew/Cellar/cmake/3.30.3/share/cmake/Modules/FindOpenMP.cmake:600 (find_package_handle_standard_args)
CMakeLists.txt:12 (find_package)

I don't know how to figure out it.

You are probably missing the installation of OpenMP on your machine. Which operating system do you have?

Hi!

There are mistakes when I compile the code, they are all similar like this:
note: explicit data sharing attribute requested here
72 | #pragma omp parallel for default(none) shared(graph)
error: variable 'from' must have explicitly specified data sharing attributes
78 | const int root_cc = smpl[from];

Should I would just remove the scope constraints.
