[kde-solaris] Compiling QT 3.1???

[Joshua Symons]

They may have put -shared back into gcc 3.2.1 for legacy support,
compiling with gcc 3.2 failed for me if I did not change the -shared to
-G. The occasional crash you are experiencing may be due to png. There
was a bug report a while back about an incompatibility between qt and a
certain version of libpng. Png is quite integrated into kde, i would
definitely research that.
libpng version 1.2.5 - October 3, 2002 is what I am currently using, try
strings libpng.so | grep version to compare. It might also be an
incompatiblity between png and zlib.
I have been running kde 3.1.rc2 now at home for app 79 days with 0
failures (Ultra 30/Solaris 8/896M of ram). I also ran kde 3.1.rc2 on
another machine (Ultra 2/Solaris 8/385M of ram) with no problems, and on
that same machine just rebuilt kde 3.1.rc6 and have been running that
for 2 days now with no problems as of yet.
