Greetings, While compiling an application on updated FC4 I got this error: /usr/X11R6/lib/libXtst.so.6: undefined reference to `__fprintf_chk@xxxxxxxxxxx' /usr/X11R6/lib/libXtst.so.6: undefined reference to `__sprintf_chk@xxxxxxxxxxx' collect2: ld returned 1 exit status Couldn't find much about it on Google, is it because of x.org or the application? Thanks -- Marius Andreiana
