I got a gcc4.1 for Centos4.5 after following your suggestions I get from ./configure --enable-gcc-hidden-visibility=yes
Your GCC supports symbol visibility, but the patch for Qt supporting visibility
was not included. Therefore, GCC symbol visibility support remains disabled.
For better performance, consider including the Qt visibility supporting patch
located at:
http://bugs.kde.org/show_bug.cgi?id=109386
and recompile all of Qt and KDE. Note, this is entirely optional and
everything will continue to work just fine without it.
Good - your configure finished. Start make now
And for Make:

I am not willing to recompile all of qt and KDE to solve this.
There has to be a better way. Can you suggest a better solution?
thanks
