And another postscriptum: This patch does *not* make Qt3 itself compatible with gcc4's -fvisibility options - it just prevents rather obscure runtime bugs in some KDE applications if KDE is compiled with visibility enabled. Do *not* attempt to compile Qt3 itself with visibility flags! Do *not* put -fvisibility=hidden or similar things into your CFLAGS/CXXFLAGS! The quickest way to get a gcc4-compiled & visibility-optimized KDE would be something like this (and remember what I wrote earlier about the performance increase you can expect before you embark on that): - Install lang/gcc40 or lang/gcc41 (my recommendation would be lang/gcc40, since KDE is completely untested with gcc41 - on any platform). - Set CC to gcc40 and CXX to g++40 - /etc/make.conf is a good place to do this, but you could also set those on portinstall/portupgrade commandlines or on make command lines. - Reinstall devel/qmake. This is important - x11-toolkits/qt33 will be compiled with the CC, CXX, CFLAGS and CXXFLAGS set at the time qmake was compiled, so it's essential to recompile and reinstall it with CC/CXX already set to gcc40/g++40. - make extract in x11-toolkits/qt33 and apply the visibility patch mentioned above, then go on with make, make deinstall, make install, make clean to recompile and reinstall Qt3. Again, this step is important - KDE will refuse to enable the visibility flags if it doesn't detect that Qt3 has been patched. - Then portupgrade -f arts\* kde\*. Again, do *not* force -fvisibility=anything into CFLAGS/CXXFLAGS yourself. KDE's configure checks will automatically set those. Check the configure out put for checking whether g++40 supports -fvisibility=hidden... checking if Qt is patched for -fvisibility... lines. Both results need to be "yes". -- ,_, | Michael Nottebrock | [EMAIL PROTECTED] (/^ ^\) | FreeBSD - The Power to Serve | http://www.freebsd.org \u/ | K Desktop Environment on FreeBSD | http://freebsd.kde.org
