Polybar: Build errors (XCB_EWMH)

[monoflo]

I could appreciate a little help building polybar. Issue #463 seems to be the most similar to what I am experiencing.

$ apt show libxcb-ewmh2 | head -n 5

Package: libxcb-ewmh2

Version: 0.4.1-1ubuntu1

Priority: extra

Section: libs

Source: xcb-util-wm

I was facing a simliar issue.
I did the following:

sudo apt-get install libxcb-ewmh-dev

Build seems to work fine after that.

[monoflo]

Tried that, but what worked for me was:

sudo apt install python-xcbgen

I then ran into other build errors outside the scope of this thread.
