I am unable to build libkscreen on a fully updated PCLinuxOS 2013 KDE 4.10.4 32 bit installation.
The failed build log shows the following towards the end :

It appears that your RPM spec file has some syntax issues.
As the syntax can vary depending on the distribution, I would suggest asking your distributions packagers for KDE software for help here.

Looks like the problem was in a .pc file as suggested by TerryN here http://www.pclinuxos.com/forum/index.ph ... msg1000720

Code: Select all

# fix broken kscreen.pc file
sed -i -e 's/VERSION/libkscreen_VERSION/' src/kscreen.pc.in

Sorry for forgetting to post the solution.

If that file is shipped as part of KScreen, you might want to post the diff on git.reviewboard.kde.org so the developers can merge the fix into the upstream sources.

Thanks for the help. I looked into the link provided and it looks beyond my current paygrade
As I said above, the solution was provided by another forum member and may be he could do it.

-SS.
