When trying to cmake a CGAL example, I get

CMake Error: Remove failed on file:
/cgal/example/CMakeFiles/CMakeTmp/cmTC_9e180.exe: System Error: Device or resource busy

Working under Win10 + Msys2.

CGAL was obtained via pacman (local/mingw-w64-x86_64-cgal 4.13-1).

Since I did not find the CGAL examples in any Msys2 package, it was copied from file /usr/share/doc/libcgal13/examples.tar.gz, which was obtained in an Ubuntu system with

$ sudo apt-get install libcgal-demo

The example is reconstruction_surface_mesh.cpp from examples/Advancing_front_surface_reconstruction.

I wouldn't know if the origin of the error is specific to my CMakeLists.txt, or else.

Related, but AFAICT not providing the answer:

  • Have you tried it in Cygwin, WSL, or a native Windows environment? It sounds like CMake is trying to delete a test executable before it finishes running. Windows doesn't allow that, but Posix does. I don't know how Msys behaves in this regard. – John Mar 05 '19 at 11:36
  • No, I did not try that. I will se if I can get such a system. – sancho.s ReinstateMonicaCellio Mar 05 '19 at 13:19
