I solved following here: http://lists.kde.org/?l=kdevelop&m=111673777924574&w=2 > QMake manager -> top window -> select src (or the subproject) -> Right mouse > click -> settings->second tab:configuration->build mode. Really it was already in debug mode.. I had to place it on release and then again on debug to have it working...
Same problem here.. on Debian etch importing a previous project or even creating the default qmake based project with kdevelop cause gdb to not see correctly the source files. I don't know if it is a probelm of kdevelop or of qmake ???? The problem is surelly on the ending dot.. I have: No source file named /data/Projects/tests/test9/src/main.cpp. Hovewer I have the file /data/Projects/tests/test9/src/main.cpp
