If you fix this, please build in the Python 3.7 side tag with: fedpkg build --target=f29-python

Comment 1 Miro Hrončok 2018-06-19 22:03:30 UTC

https://wxpython.org/news/wxpython-4.0.2-release/index.html

> Updated the waf tool used by the build to version 2.0.7. This fixes problems with building for Python 3.7.


Please either update (I've seen that's blocked) or backport the fixer.

Comment 2 Scott Talbert 2018-06-20 21:07:20 UTC

Fixed in f29-python tag.
