provide symbol dbg package (Linux)

[Daniel Schürmann]

When hunting bugs sometimes the produced back traces from the users are not that significant because our build server produces striped version of Mixxx.

It would be nice, if the build server can also produce the symbol or map files. So that we at least are able to interpret the the addresses from provided back traces .

The best would be to provide a mixxx-dbg.deb that will install the symbol files at user's machine.

Is it enought to use pkg_create_dbgsym during the build?

[Daniel Schürmann (daschuer)]

Is this a candidate foe 1.12?

[Daniel Schürmann (daschuer)]

It is now available at
https://launchpad.net/~nschloe/+archive/ubuntu/mixxx-nightly

Set the status at in progress for now since our stable ppa should have the debug symbols as well.

[RJ Skerry-Ryan (rryan)]

Hm, I didn't realize our debs stripped the binaries. I think we can just remove dh_strip from our debian rules file.

[Daniel Schürmann (daschuer)]

I would prefer to provide a dbg package, because this is will be the standard when shipped by a distribution.
Nico has a solution. Can we adopt it?

[Daniel Schürmann (daschuer)]

Status:
Debug packages are available here:
https://launchpad.net/~nschloe/+archive/ubuntu/mixxx-nightly
But not here:
https://launchpad.net/~mixxx/+archive/ubuntu/nightlies/

What is to do to have them at the second repository as well?

The same on windows: Bug #1456107
How is the status on mac?

[Daniel Schürmann (daschuer)]

This bug blocks a solution for other bugs like this:
Bug #1495317

@ywwg: can you provide a mixxx-dbg.deb from our build server?
Are we able to create a map file for
Mixxx "1.12.0-beta1" "(git 1.12 r5545; built on: Sep 2 2015 @ 04:11:05;
This will help on Bug #1495317

Who has access to
https://launchpad.net/~mixxx/+archive/ubuntu/mixxxbetas/+packages
https://launchpad.net/~mixxx/+archive/ubuntu/nightlies
and can add a dbg package like Nico did on his ppa?

[RJ Skerry-Ryan (rryan)]

Nico -- what did you have to change to get this working?

[Nico Schlömer (nschloe)]

On the PPA page:

Change Details -> Build debug symbols

and/or

Change Details -> Publish debug symbols

Both are off on https://launchpad.net/~nschloe/+archive/ubuntu/mixxx-nightly which has me a little confused, but anyhow that's probably what you should try.

[RJ Skerry-Ryan (rryan)]

I just enabled 'Build debug symbols' and 'Publish debug symbols' for all 3 of our official PPAs.

[RJ Skerry-Ryan (rryan)]

Latest beta builds have a "mixxx-dbgsym" package alongside "mixxx":
