whether or not the list command works is irrelevant. this command requires the source code to be available. the problem is line number information in the binary and not file name information. it did work with -g but -ggdb does not work. this may be a bug in gcc or gdb. addtitionally gcc-2.96-97 is not even on the rawhide site! It is, and you should use "-g", not "-gdb". The compiler was available shortly after from Rawhide, but didn't have anything to do with the report. |
