Hello, I have some troubles compiling kdebase SVN 1260891 on Fedora 15. I guess this is because the "direct linking" is now disabled by default on this distro. https://fedoraproject.org/wiki/UnderstandingDSOLinkChange ========== /usr/bin/ld: CMakeFiles/nspluginviewer.dir/nsplugin.cpp.o: undefined reference to symbol 'dlsym@@GLIBC_2.2.5' /usr/bin/ld: note: 'dlsym@@GLIBC_2.2.5' is defined in DSO /lib64/libdl.so.2 so try adding it to the linker command line /lib64/libdl.so.2: could not read symbols: Invalid operation collect2: ld returned 1 exit status make[2]: *** [nsplugins/viewer/nspluginviewer] Error 1 make[2]: Leaving directory `/home/albator/rpmbuild/BUILD/kdebase/build' make[1]: *** [nsplugins/viewer/CMakeFiles/nspluginviewer.dir/all] Error 2 ========== Linking CXX executable kdesktop_lock cd /home/albator/rpmbuild/BUILD/kdebase/build/kdesktop/lock && /usr/bin/cmake -E cmake_link_script CMakeFiles/kdesktop_lock.dir/link.txt --verbose=1 /usr/lib64/ccache/c++ -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -DQT_NO_ASCII_CAST -DQT_CLEAN_NAMESPACE -DQT_NO_STL -DQT_NO_COMPAT -DQT_NO_TRANSLATION -DQT_THREAD_SUPPORT -D_REENTRANT -include tqt.h -ldl CMakeFiles/kdesktop_lock.dir/lockprocess.cc.o CMakeFiles/kdesktop_lock.dir/lockdlg.cc.o CMakeFiles/kdesktop_lock.dir/infodlg.cc.o CMakeFiles/kdesktop_lock.dir/querydlg.cc.o CMakeFiles/kdesktop_lock.dir/sakdlg.cc.o CMakeFiles/kdesktop_lock.dir/securedlg.cc.o CMakeFiles/kdesktop_lock.dir/autologout.cc.o CMakeFiles/kdesktop_lock.dir/main.cc.o -o kdesktop_lock -rdynamic -L/opt/trinity/lib64 -L/usr/lib64/qt-3.3/lib ../libkdesktopsettings.a ../../kdmlib/libdmctl.a /opt/trinity/lib64/libkio.so.4.2.0 -lGL -lXau /opt/trinity/lib64/libkdeui.so.4.2.0 -lfreetype -lfontconfig /opt/trinity/lib64/libkdesu.so.4.2.0 -lutil /opt/trinity/lib64/libkwalletclient.so.1.0.1 /opt/trinity/lib64/libkdecore.so.4.2.0 /opt/trinity/lib64/libDCOP.so.4.2.0 /opt/trinity/lib64/libkdefx.so.4.2.0 -ltqt -lqt-mt -lXrender -lX11 -lz -lXcomposite -lICE -lSM -Wl,-rpath,/opt/trinity/lib64:/usr/lib64/qt-3.3/lib: /usr/bin/ld: CMakeFiles/kdesktop_lock.dir/lockprocess.cc.o: undefined reference to symbol 'DPMSInfo' /usr/bin/ld: note: 'DPMSInfo' is defined in DSO /usr/lib64/libXext.so.6 so try adding it to the linker command line /usr/lib64/libXext.so.6: could not read symbols: Invalid operation collect2: ld returned 1 exit status make[2]: *** [kdesktop/lock/kdesktop_lock] Error 1 make[2]: Leaving directory `/home/albator/rpmbuild/BUILD/kdebase/build' make[1]: *** [kdesktop/lock/CMakeFiles/kdesktop_lock.dir/all] Error 2 ========== To sum up things, I can compile if I set the following variable export LDFLAGS="-ldl -lXext" Thanks Francois Andriot
