DLL load failed
Closed this issue · 3 comments
After building the wheel package using
python -m build -w
I ran:
pip install gdstk/dist/gdstk-0.9.51-cp311-cp311-win_amd64.whl
to install and when I try to use it, it cannot find methods and classes etc inside it and shows this error.
Is there any specific reason not tu use the pre-compiled packages from PyPI?
Compilation in Windows requires a few dependencies and the build system properly configured. If you share your build logs maybe we can help identify the issue.
there is some enterprise level business logic that I would like to implement in gdstk without it being pushed to the public package, so I'm trying to make some changes and build the python module myself. I previously installed zlib and qhull with vcpkg (I'm not sure if this is the correct approach, this could be where my issue is) as I was having issues with:
This is also the same issue I get when I pip install the tar.gz file in releases
So I included these at the top of the CMakeLists file which allowed me to build the python package fine, but when I pip install either the tar.gz file or the .whl file I get that error
Yes, you're not successfully compiling the module, so the DLL is not generated. I don't really use Windows so I don't know how much help I can offer, but I think you'll want to have ZLIB_INCLUDE_DIRS and ZLIB_LIBRARIES (note the plural) in the in your evironment, not as a CMake variable: see here
