I'd like to use QtCreator to debug my program on Unbuntu Linux. But the creator told me that no debug version is built. Somehow in the Internet I've found that gdb must be installed in order to be able to debug.
1. How can I see if this is installed? I've a quite old Utuntu version (which is not any more supported) and maybe the gcc version is old, too.
2. How can I find out which version my gcc have?
3. Must certain version of gdb be installed so that it can work with certain gcc version?
Thanks for clarification!
