 Posted: Fri Jul 19, 2024 12:07 pm Post subject: [SOLVED] postinst-qa-check.d/50xdg-utils trap invalid opcode |
 |
|
Hello,
So I have a gentoo musl installation using -march=bdver2 (amd) and I wanted to use it on an old atom (-march=bonnell) motherboard.
I first started by changing :
| Code: | COMMON_FLAGS="-march=bdver2 -O2 -pipe"
CPU_FLAGS_X86="mmx mmxext sse sse2 sse3 sse4_1 ssse3" |
to
| Code: | COMMON_FLAGS="-march=x86-64 -O2 -pipe"
CPU_FLAGS_X86="mmx mmxext sse sse2 sse3 ssse3" # (instructions supported by the atom motherboard) |
then rebuilt @system and moved the rootfs to a new subvolume on the atom motherboard (it has a working gentoo glibc installation)
Then from the atom box, I chrooted in the musl rootfs subvolume then changed :
| Code: | | COMMON_FLAGS="-march=x86-64 -O2 -pipe" |
to
| Code: | | COMMON_FLAGS="-march=bonnell -O2 -pipe" |
then started a full system rebuild (to be followed by @world after that) :
| Code: | | emerge -aq --emptytree --usepkg=n @system |
Rebuild is going smoothly at the moment but I'm seeing a ton of trap invalid opcode in my dmesg related to update-desktop-database.
| Code: | | traps: update-desktop-[19882] trap invalid opcode ip:62e511caf50d sp:7fffee01fc90 error:0 in update-desktop-database[62e511caf000+2000] |
After looking around briefly, it seems related to : /usr/lib/portage/python3.12/postinst-qa-check.d/50xdg-utils and the fact I use qa in PORTAGE_ELOG_CLASSES because each time a package is installed and update-desktop-database called then a new trap code is issued. Strangely, I don't have xdg-utils installed so it seems independent from xdg-utils.
Will it go away when @system (and @world) is fully rebuilt ?
Thanks

I found the issue..
In fact, it is not related to xdg-utils (I was confused by the name : /usr/lib/portage/python3.12/postinst-qa-check.d/50xdg-utils ) but to dev-util/desktop-file-utils
In /usr/lib/portage/python3.12/postinst-qa-check.d/50xdg-utils
| Code: | # Check for missing calls to xdg-utils regen functions
xdg_desktop_database_check() {
type -P update-desktop-database &>/dev/null || return
[...] |
So after rebuilding dev-util/desktop-file-utils :
| Code: | /usr/bin/desktop-file-validate
/usr/bin/desktop-file-install
/usr/bin/update-desktop-database |
then no more trap invalid opcode. Rebuild with -march=bonnell still in progress. Will likely end in days.. 
I guess that's because I only rebuilt @system (I was lazy and wanted to save time) when I switched from bdver2 to x86-64 (before moving the installation) and since this package is not part of @system, that's why I was receiving those trap invalid opcode. |
