I want to report a bug. Since I built webkit using update-webkitgtk-flatpak and then build-webkit, I can't use the normal system coredumpctl to get a backtrace: I have to go through webkit-flatpak. I try this: $ webkit-flatpak --gtk -m 19974 --gdb where 19974 is the pid of the crashing web process. It (unexpectedly?) fetches a bunch of git repos, then opens up gdb: Core was generated by `/home/mcatanzaro/Projects/WebKit/WebKitBuild/Debug/bin/WebKitWebProcess 5 37'. Program terminated with signal SIGSEGV, Segmentation fault. #0 0x00007f4b2cf00629 in ?? () [Current thread is 1 (LWP 19974)] (gdb) bt #0 0x00007f4b2cf00629 in ?? () #1 0x00007ffc1d9d2290 in ??

() It's really great that we have the --gdb and -m functionality built-in, but there's no debuginfo so I don't understand how to use it. 1450700 1 mcatanzaro 2018-08-16 08:57:43 -0700 Just found this in org.webkit.WebKit.yaml: build-options: cflags: -O2 -g cxxflags: -O2 -g strip: false no-debuginfo: true I don't know why we're using no-debuginfo: true, but that seems pretty unfriendly for a runtime that's exclusively intended as a developer tool. Thibault, can we change that, or is there an important reason for it? 1450702 2 mcatanzaro 2018-08-16 08:58:23 -0700 I guess that controls what we build ourselves though, not the runtime. We need org.gnome.Sdk.Debug to be installed. 1450715 3 mcatanzaro 2018-08-16 09:56:14 -0700 I'm running 'update-webkitgtk-flatpak' right now and it is installing debuginfo. Perhaps I hadn't set debug configuration last time I ran it? Not sure. We'll see what happens.... 1450722 4 tsaunier 2018-08-16 10:03:42 -0700 (In reply to Michael Catanzaro from comment #3) > I'm running 'update-webkitgtk-flatpak' right now and it is installing > debuginfo.

Right, Sdk.Debug is installed only when `--debug` is passed. 1631075 5 pnormand 2020-03-18 03:16:38 -0700 Seems like all is solved now? I'll assume so and close. Please reopen if needed!
