Building latest release of KDE

[Thomas Friedrichsmeier]

Hi,

this is a terribly late reply. I wish somebody from the "inner circle" would 
answer such questions, as I really find the situation rather non-obvious, too, 
and I can't really give any definite answers.

Anyway, I can give you some pointers:

Some things to be noted:
- As there is not even a branch for KDE 4.14 in emerge, I would expect it to 
be a prohibitive amount of work to build KDE 4.14 on Windows. Perhaps you do 
not really need the very latest okular? Perhaps the one coming with KDE 4.13 
would be good enough.
- You do not necessarily need all of KDE 4.14 in order to build the latest 
okular. At least its CMakeLists.txt suggests KDE 4.6.0+ is required, only. But 
of course it's quite possible that nobody adjusted the dependency setting in a 
while, and it's totally out-of-date.
- So what I'd suggest is: Try building KDE 4.13. If you _really_ need a more 
recent okular, modify the okular portage file 
(emerge/portage/kde/kdegraphics/okular/okular.XYZ.py) to point to the latest 
stable git branch, instead of the KDE/4.13 branch (the "gitHEAD" target). Try 
if that works.

Now the big caveat:
- In my experience, building a not-so-recent KDE release on Windows is a 
really cumbersome exercise, as many downloads referenced have moved or are no 
longer available at all. I'm not sure, what state the kde-4.13-branch is in.
- Personally, I'm really glad, I made a snapshot of my kde-4.10 emerge tree, 
and use that for building. Good enough for me, _might_ be good enough to build 
a recent okular (see above). Just in case you hit a dead-end on kde-4.13, and 
you want to give that a try: 
http://sourceforge.net/projects/rkwardextras/files/Windows/Development/ .

No idea on the compiler issue.

Regards
Thomas
