Hi, For the past few days I get this error every time I try to compile kdelibs. /usr/bin/ld: .libs/libkdefx.so.4.0.0: undefined versioned symbol name clog@@GLIBC_2.1 /usr/bin/ld: failed to set dynamic section sizes: Bad value collect2: ld returned 1 exit status make[2]: *** [libkdefx.la] Error 1 make[2]: Leaving directory `/opt/progs/cvs/kde/kdelibs/kdefx' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/opt/progs/cvs/kde/kdelibs' make: *** [all-recursive-am] Error 2 I'd appreciate it if anybody could clue me in as to what clog@@GLIBC_2.1 is and how I can fix the problem it's having. Some details: I'm compiling on a RedHat 7.1 system with lots of updates. My glibc is 2.4 (I think). QT is the latest qt-copy from CVS. It's configured and compiled for the linux-g++-objprelink platform. I compile kdelibs with objprelink enabled also. Thanks, Seth
