gdb 9.2 asserts when connecting to libogc's gdbstub

Post by phire » Sat Nov 28, 2020 10:54 pm

When I try to debug the remote target (wii gdbstub example via usb gecko) with gdb 9.2, I get the following error:

Code: Select all

Reading symbols from gdbstub.elf...
../../gdb/inferior.c:283: internal-error: inferior* find_inferior_pid(int): Assertion `pid != 0' failed.
A problem internal to GDB has been detected,
Googling around, it looks like a GDB issue and this patch appears to fix it. The patch is included in gdb 10.1 (well, with several improvements on-top of it), so I guess a simple option is to simply upgrade.

BTW, I was going to test upgrading to gdb 10.1 myself, but I couldn't find the PKGBUILD for gdb or any of the toolchain in the devkitPro/pacman-packages repo. Am I blind, or is it hiding away in another repo I can't find?

I had a look at gdb 10.2 and it's stil not working. I've just moved the devkitPPC-gdb package to 7.6.2 for now - that appears to work. There may be later versions that work but I had issues getting later 7.x trees to compile for all the platforms & I don't have a whole heck of a lot of spare cycles just now. You'll need to explicitly install it - pacman won't automatically install a lower version.

FFWIW this gdb is just a vanilla gdb compiled for a powepc-eabi target, there's nothing particually special about it. If we do any major patching then we'll add those to the relevant repo, in this case

The tool PKGBUILDs are held in a separate repo that's currently private after a bit of drama. tl;dr; someone started making a PR that conflicted with changes that hadn't yet been pushed to the public repo and threw a hissy fit when they were told that it couldn't be accepted & they should stop. I'll possibly make it public again at some point but I'm in the middle of refactoring some things in there so I don't really want to deal with issues or PRs on the repo until that's done.
