pip install pyscard does not work

[githubkusi]

It would be great to have a wheel for pyscard.

(venv) $ pip install pyscard
Collecting pyscard
  Using cached pyscard-2.0.3.tar.gz (150 kB)
  Preparing metadata (setup.py) ... done
Using legacy 'setup.py install' for pyscard, since package 'wheel' is not installed.
...

Installing wheel, then I get

(venv) $  pip install pyscard

Is there a way to install everything in a venv or by means of pipx? System: Opensuse Tumbleweed, Python 3.8

It looks like the last error comes from swig-pypi.

have you tried to install the OpenSUSE swig package instead? https://software.opensuse.org/package/swig

You may also have to install the OpenSUSE package libpcsclite-dev https://software.opensuse.org/package/libpcsclite-dev to solve the problem:

      Package libpcsclite was not found in the pkg-config search path.
      Perhaps you should add the directory containing `libpcsclite.pc'
      to the PKG_CONFIG_PATH environment variable
      Package 'libpcsclite', required by 'virtual:world', not found

[githubkusi]

yes, installing the opensuse swig package brings me indeed further. libpcsclite-dev is also needed for winscard.h. I intend to prepare a multi-platform (mac & linux) package where it would be very helpful to have a wheel such that it can be completely installed in a venv rather than touching the system. Would you consider a wheel for pyscard?

[LudovicRousseau]

I use swig to create the connection between Python and C. A Python wheel package then have a part of native code compiled. This binary depends on the Python version and also the CPU architecture.

I already provide wheels for Windows. Because installing the dependencies on Windows is "complex". See https://pypi.org/project/pyscard/#files

I am no sure it is possible to create a multi-platform wheel for pyscard. But please do try it by yourself. Feel free to send me patches.

[githubkusi]

This one could be of help: https://github.com/pypa/cibuildwheel, with an example for appveyor what you are using

[LudovicRousseau]

Please provide a patch. I do not plan to work on multi-Python and multi-OS wheel myself.

This is now a different subject. I close this issue as it is resolved.
