<pre>I try to build openMP using
cmake -DLLVM_ENABLE_PROJECTS="clang;openmp" -DLLVM_TARGETS_TO_BUILD=X86
-DLLVM_ENABLE_RUNTIMES=“compiler-rt; libcxx;libcxxabi;libunwind” -G "Unix
Makefiles" -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64" ../llvm
-DCMAKE_BUILD_TYPE=Release
Then I integrate openMP into Xcode12, it compiled successfully, but it was
crashed when open app.
crash info:
OMP: Error #178: Function Can't open SHM2 failed:
OMP: System error #1: Operation not permitted
Note:
1. I used Xcode user-defined CC="path to clang", other C Flag = '-fopenmp'
2. I used llvm master code
3. It worked in apple silicon machine.
4. It worked in branch 9.x
How can I successfully integrate openMP?</pre>
