Last week, an upgraded gcc compiler suite (version 4.4.2) was added to slackware-current . The new Gnu C compiler reveals software compilation issues in several programs that did not occur with the previous version of the Gnu C compiler. A nice summary of issues you may encounter when building software using the scripts at SlackBuilds.org can be found on Ponce’s blog, along with the solutions he found that fix these errors.
So far, I only ran into one compilation issue (actually it was reported first on LQ: http://www.linuxquestions.org/questions/slackware-14/alien-bobs-vlc-slackbuild-fails-on-current-781414/), when compiling VLC and to be more specific, compiling the twolame library which I add to my VLC package for Slackware.
The error you will get is this:
?psycho_2.c:203: error: array subscript is above array bounds
The fix is simple. One file needs a patch:
--- twolame-0.3.12/libtwolame/psycho_2.c.orig 2008-01-09 12:06:21.000000000 +0100
+++ twolame-0.3.12/libtwolame/psycho_2.c 2010-01-11 15:15:28.000000000 +0100
