Hi list, I've been trying to get new Python 3.8 builds for the MapServer project - these are SWIG-generated bindings that require many DLLs to import in Python. Up until now this worked by adding a folder to the top of the Windows PATH.
I've read through the discussions at https://bugs.python.org/issue36085 and understand the reasoning behind the change. Is the recommended solution in cases of Python wrappers to create a project-specific environment variable and allow users to set this, which in turn the library adds with add_dll_directory? However, there is one feature of using the Windows PATH that I can't seem to replicate with add_dll_directory. The MapServer DLL builds are linked to sqlite3 3.24.0, whereas Python 3.8.2 is linked to 2.6.0. Building with matching versions is not something I can easily change. When using Windows PATH the folder with the newer version could be added to the front of the list to take priority and import worked correctly. This does not seem to be possible with add_dll_directory - the Python sqlite3.dll in C:\Python38\DLLs always takes priority leading to: ImportError: DLL load failed while importing _mapscript: The specified procedure could not be found. I presume I can't remove the C:\Python38\DLLs path, is there another solution to this issue? Thanks in advance for any help, Seth -- web:http://geographika.co.uk twitter: @geographika _______________________________________________ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/I6JAXBKV4Y7MVF42RJ4XQIPYQMAVXHOF/ Code of Conduct: http://python.org/psf/codeofconduct/
