Compilers are pretty good at telling you what they’re unhappy about these days so you’re well on the track as opposed to chasing bugs in gdb. Usually when I get to the stage where whatever I’m working on is ready to build I pipe stderr to a file and just go down the list fixing all the little things until it works (or usually segfaults). I’ve successfully updated quite a few super old codebases to play around with by just fixing each compiler error until it works or I have to go hunting real bugs.
