Building on Centos 7: invalid conversion from ‘const Pix*’ to ‘Pix*’ #63
Description
What steps will reproduce the problem?
1. Followed the Centos 6.3 instructions in the wiki up to "python setup.py
build".
3. That command gives several errors when running it on Centos 7 (CentOS Linux
release 7.0.1406). See log output below.
$ sudo python setup.py build
Your os is:linux
..........
Current Version : 0.9
os=linux
