It turns out there is a `remove_command` API in debhelper, so
dh-golang/1.58 now calls `remove_command('dh_dwz')`.

Now with golang-1.19, all Go packages ftbfs with dwz: Found compressed .debug_aranges section, not attempting dwz compression Could the debhelper ignore the dwz error? Or can a debhelper addon (e.g. dh-golang) be allowed to override dh_dwz globally? -- Shengjing Zhu

There is some discussion, if dwz should decompress, do it's work and compress it again. However until then, don't use compressed debug sections. Apparently these are turned on by the upstream build system. debhelper maybe could warn about compressed debug sections in general. Would would you want to have those anyway? The packages are compressed, and you shouldn't care about the on-disk space when debugging. There's also discussion, about errors: https://sourceware.org/bugzilla/show_bug.cgi?id=24766 Apparently the RPM based helpers ignore the return value of dwz, and leave the debug symbols unhandled. Again, debhelper could warn about such packages when built in compat12 mode. Matthias

Error when running dh_dwz (actually an error when running dwz(1))
Dear -devel list, Looks like dh_dwz was recently added into debhelper and it is causing some FTBFS on one of my packages. It could be a bug of dwz itself but I'm looking for some help inside Debian first. Please try to build package marisa from its git packaging repo ( https://salsa.debian.org/input-method-team/marisa/commit/f5ff598466266b230d68c9db9f8e31281604b7a6 ). The following error will pop up when dwz is called: = [...] dh_dwz dwz: debian/ruby-marisa/usr/lib/x86_64-linux-gnu/ruby/2.5.0/marisa.so: Found compressed .debug_aranges section, not attempting dwz compression dh_dwz: dwz -q -- debian/ruby-marisa/usr/lib/x86_64-linux- gnu/ruby/2.5.0/marisa.so returned exit code 1 make: *** [debian/rules:30: binary] Error 1 dpkg-buildpackage: error: fakeroot debian/rules binary subprocess returned exit status 2 = I don't have much experience of dealing with debugging symbols so any hints would be appreciated.
