[bugproxy]

With Ubuntu 20.04 no libgomp1-dbg were made available.

Last shipment is focal.

Canonical, please provide libgomp1-dbg, also for focal and beyond..

[Frank Heimes (fheimes)]

I wasn't able to directly mark this ticket as affecting libgomp (or libgomp1),
but since libgomp belongs to gcc and 20.04 comes with gcc-10:
https://launchpad.net/ubuntu/+source/gcc-10/
marking this as affecting ggc-10.

[Frank Heimes (fheimes)]

But since 9.2.1-20ubuntu3 gcc '-dbg' packages are no longer build.
See changelog:
https://launchpad.net/ubuntu/+source/gcc-9/9.2.1-20ubuntu3
"Stop building -dbg packages, keep building the libstc++6-9-dbg package
 containing just the libstdc++ debug build"

[Matthias Klose (doko)]

this is expected. you need to install the packge from the dbgsym archive:
https://wiki.ubuntu.com/Debug%20Symbol%20Packages

[Chris Parich (cparich)]

After adding repositories from https://wiki.ubuntu.com/Debug%20Symbol%20Packages, libgomp1-dbg and libgomp1-dbgsym are both still missing

$ cat /etc/apt/sources.list.d/ddebs.list
deb http://ddebs.ubuntu.com focal main restricted universe multiverse
deb http://ddebs.ubuntu.com focal-updates main restricted universe multiverse
deb http://ddebs.ubuntu.com focal-proposed main restricted universe multiverse

Actually I really do not see any dbg packages for gcc-10 on any architecture.

Reading the build log, I see that it was built with:

DEB_BUILD_OPTIONS=noautodbgsym parallel=4

meaning do _not_ generate autodbgsym packages. And I'm not sure why. Given that we expect gcc-10 to generate dbgsym packages.

[Dimitri John Ledkov (xnox)]

I see in launchpad-buildd
  * lpbuildd.binarypackage: Pass DEB_BUILD_OPTIONS=noautodbgsym if we have
    not been told to build debug symbols (LP: #1623256).

[Dimitri John Ledkov (xnox)]

@doko

I think the gcc-10 that was built for Focal release was built in https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/binutils

And it appears that says archive does not have building & publication of debug symbols on.

Can I please be added to ~ubuntu-toolchain-r to double check the settings of that repository? At the momemnt, it looks like they are not sufficiently correct to copy packages from there into the archive.

If you need spare locations to build toolchains, it is best to build them in Bileto PPAs as they are always correctly configured devirt & dbgsymbols on.

I confirm this was the case. I have now set the option on the ppa to build
the debug symbols packages.

[Dimitri John Ledkov (xnox)]

The next SRU of the toolchain will be build with debug symbols. I don't have timelines when the next toolchain SRU is going to happen. As toolchain rebuild requires extensive validation, and thus we should bundle this issue with other fixes we will bundle.

Any news, when the next toolchain bundle will be released?
Many thx in advance

[Dimitri John Ledkov (xnox)]

I've spoken with Matthias, the current schedule is to wait for the upcoming 10.2 release, push that to groovy, and generate 9 & 8 snapshots around the same time, and push them out as SRUs. The expected timeline is August/September.

This fix will be included in that SRU.

[Matthias Klose (doko)]

the plan is to backport the GCC 10.2 release to 20.04 LTS once it is released.

[Frank Heimes (fheimes)]

Meanwhile gcc 10.2 landed in focal:
gcc-10 | 10.2.0-5ubuntu1~20.04 | focal-updates/universe
and with that gcc-10 debug symbols are available 'gcc-10-dbgsym' as well as 'libgomp1-dbgsym':
$ apt-cache policy libgomp1-dbgsym
libgomp1-dbgsym:
  Installed: 10.2.0-5ubuntu1~20.04
  Candidate: 10.2.0-5ubuntu1~20.04
  Version table:
 *** 10.2.0-5ubuntu1~20.04 500
        500 http://ddebs.ubuntu.com focal-updates/main s390x Packages
        100 /var/lib/dpkg/status
Closing this ticket as Fix Released.
