Hi, I'm building a project using KDevelop 3.5.4 and Qt4.2. I want do debugging it, but I have no success. The error happens on the link step and error message is: /usr/lib64/gcc/x86_64-suse-linux/4.1.0/../../../../x86_64-suse-linux/bin/ld: cannot find -lQtGui_debug collect2: ld returned 1 exit status gmake[1]: Leaving directory `/home/thadeu/projC/gtom3/src' gmake[1]: *** [../bin/gtom3] Error 1 gmake: *** [sub-src-make_default] Error 2 *** Exited with status: 2 *** I search for QtGui_debug but not found it. Somebody can help me? Thank you Thadeu
