Description Neal Gompa 2015-10-09 02:29:11 CEST

Description of problem:
When Python 3.5 replaced Python 3.4 in Cauldron, various CMake-powered libraries (like hawkey, librepo, libcomps, etc.) failed to detect Python 3.5 properly and thus failed to build. This is fixed in CMake 3.4.0 RC1, which I have provided the necessary RPM SPEC patch

Version-Release number of selected component (if applicable):
3.3.2-1.mga6



Reproducible:

Please just first upload current cmake version with FC patch:
http://pkgs.fedoraproject.org/cgit/cmake.git/tree/cmake-python3.5.patch?id=4798c1522a921a6756ae70b5e64c91d8697b6a88

I've live tested a similar change against /usr/share/cmake/Modules/FindPython* and it enabled me to build libsolv which fails to build with current cmake+py3.5

Else, in case new cmake version failed to build, we'll be be left in frozen hell :-)

Added an alternate patch for adding Python 3.5 detection support to CMake 3.3.2

Incidentally, I did test my patch to be sure it built and installed properly on my Cauldron box. I don't know how much that says about it working in iurt, but at least there's that.

I've already pushed cmake 3.4.0-rc1. I'm closing this as FIXED.
