Hello, I am trying to install pywm with pip in a Debian sid machine. However, I get the following error. I have libseat and libseat-dev already installed at the version 0.7.0, so I am not sure what the problem is. I would be happy if someone could help.

This prints the repr of a bytestring which is kind of... bad... for reading. After copy/pasting the line into a python shell and using print(var.decode('utf-8')) I get something halfway sane as a status:

Two points to note:

  • this project doesn't use the system wlroots:

    pywm/meson.build

    Line 47 in 6cd58ed

    wlroots = subproject('wlroots', default_options: ['default_library=static']).get_variable('wlroots')
  • apparently libseat-dev is NOT found, because... wlroots| Run-time dependency libseat found: NO (tried pkgconfig and cmake)

The problem was related to the Debian version of the libseat package. As soon as I updated it today, pywm got installed.
