ninja: build stopped: subcommand failed.

Note: libmusicbrainz is rather old, the sources in @wiiaboo fork at least 3 years, the xmlParser even 9 years. So the reason must be external. Possibly a sudden incompatibility with the newest GCC?

BTW, the original repo has no "issues" page.

I have also encountered the same problem, and there is no better solution yet. I suspect that:

XmlErrorPtr is defined in libxml2, does it lack a search path?

I don't have a path of local32/include/libxml2.

Can you try https://github.com/m-ab-s/media-autobuild_suite/commit/e9c402e7a0cc9ccd03def6479efdcec0a8b0642d ? It seems it's due to changes done in libxml2 with transitive includes.

Can you try e9c402e ? It seems it's due to changes done in libxml2 with transitive includes.

Success, thank you!

I guess you build without vulkan ? any hints on how to get a working build would be much appreciated.

Today I was able to build everything, non-free license, almost every module enabled.

Before running the suite I removed all the subdirectories in build and local## to enforce a completely fresh download and build of all sources.

media-autobuild_suite.ini.txt ffmpeg_options.txt

The only patch which failed was the "cabac not inline" patch for ffmepg.
