@patrick96 fixed it.

For the record, my problem was that I had a virtualenv plugin in my shell that was throwing a non-system python binary earlier in my PATH.

Anyone else having this issue: type python3. Make sure your system python is the one you're using when building.

@clpwn xcbgen detection works fine for me. Do you use Anaconda for python? If so, there is a known issue with xcbgen detection: https://github.com/jaagr/polybar/wiki/Known-Issues#missing-required-python-module-xcbgen-with-anaconda

Otherwise you may be experiencing the same issue as in https://github.com/jaagr/polybar/issues/1496. The OP has yet to provide us with the results of our troubleshooting instructions. If anaconda is indeed not the problem, we would appreciate it if you could go over to the linked issue and help with troubleshooting.

Even with reinstalling xcb-proto, I get this error while building. Just me?

CMake Error at lib/xpp/CMakeLists.txt:70 (message):
  Missing required python module: xcbgen

it was a problem with xcbgen, like in this closed issue https://github.com/jaagr/polybar/issues/502

I resolved it by reinstalling xcb-proto package. Thanks for the help!

@nathias That error shouldn't affect the build. What error is actually printed in the terminal, when the build fails?

@patrick96 sorry, I assumed there was a recurring issue. The error is pthread_create exist failed... my error log is here: https://gist.github.com/nath1as/f3a0b68c8168b7537dee5ffc20949fd3

@nathias, I just tested this, there are no build errors on my machine. You'll need to be a little more specific.

there are build errors again

This package should now build without issues again.

With the new jsoncpp version (1.8.3) the polybar build may fail, if that happens, you have to apply this [1] patch to the i3ipcpp submodule.
