Details

Arch Linux does not ship with debugging symbols in packages, a discussion on inclusion for that went silent[1].

KDE programs do not often crash, but when they do, I do not have any useful debugging symbols. Today I had KMail crashing out of nothing. The backtrace contained a lot ??? as there are no debugging symbols.

As I do not forsee special debugging repositories, please consider:

* Storing the build environment in a .pkg.tar.xz, consisting of:
- `env`, especially something like CFLAGS)
- version of packages and compiler (or a reference to a set of package versions of base and base-devel)
* Saving the results of builds, Debian has a very nice place, "Developer Information (PTS)"[2] that also links to build logs[3].
* (creating a repo with debugging symbols anyway)
* (creating a debugging package for qt4 and the like)

Discussion is welcome.

CFLAGS are standardised in Arch and the version of packages matter little given you will need to test if the build fails under current conditions to replicate/fix.

Not a pacman issue.

Allan, CFLAGS change over time as do the package versions. I am assuming that if the base environments are equal, then the produced assembly/binaries should also be the same. Things like machine names, kernel version and time may also have an effect on the resulting binaries, but it shouldn't change too much.

A core dump is useless (or hard to debug) if there are no debugging symbols giving a starting point.

Necrobump here, we now have a BUILDINFO which solves part of this problem. A separate debug repo is still an todo item.
