Failing to build functional manylinux wheels #191

Closed philipdouglas closed 3 years ago

philipdouglas commented 3 years ago

I've been using the instructions that @hoefling shared in an older issue for building python xmlsec into a manylinux wheel to build one in order to deploy on an Ubuntu server, where I can't get the package to build locally.

I have successfully built the wheel, and it installs fine (both in the docker container and on the Ubuntu server), but when I try to import xmlsec in python, I get this error:

>>> import xmlsec

xmlsec.Error: (1, 'cannot load crypto library for xmlsec.')

Note: this is with PYXMLSEC_ENABLE_DEBUG=1 in order to check that the crpyto library was the one I thought it was.

Am I missing something in the wheel build process?

It turns out the problem was I was using STATIC_DEPS instead of PYXMLSEC_STATIC_DEPS which meant it didn't actually build with static dependencies. I did actually try the latter yesterday, but there was a problem with the libxslt build that made me think it hadn't work, which I've raised in #192.
