Compiling pillow for a debug build fails without -j1 because distutils parallelizes the build, but there are problems with locking the .pdb file during when compiling the C files. An example of the error message from a cl.exe command is:
fatal error C1041: cannot open program database 'C:\src\tmp\pillow-test\Pillow-7.2.0\vc140.pdb'; if multiple CL.EXE write to the same .PDB file, please use /FS
Building works with setup.py build_ext --disable-jpeg --disable-tiff --disable-zlib --debug build -j1
My guess is the fix is not to parallelize by default in a debug build; a /FS arg to cl.exe could be used, but that doesn't seem to be recommended.
I realize this might be considered a pillow bug, but my guess is that it affects other packages as well |
