Bug 545388 – media-libs/imlib2[ABI_X86="64 32"] doesn't find -lbz2

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description jannis 2015-04-03 09:32:25 UTC]

I'm currently migrating from emul-linux-x86* packages to true multilib and imlib2 fails stating it cannot find a symbol of bzip2 (see build.log).
I found out that the emul-linux-x86 package containing bzip2 installed the libraries to /lib32 whereas bzip2 with multilib support installs the 32bit-libraries to /usr/lib32. So this might actually be a bug of bzip2's multilib support.

Reproducible: Always

It's the same with media-libs/freetype-2.5.5

Chances are you're doing the migration wrong - by the time you've reached imlib2/freetype2, both zlib and bzip2 should already be emerged with abi_x68_32.

That's why the news item had had the intermediary broken phase.

[Comment 6 jannis 2015-04-05 22:46:06 UTC]

Yeah, sure, they are emerged with abi_x86_32. What I did:
- unmerge all emul-linux-x86* packages. That left the actual libraries in the system as preserved ones
- migrate by emerging some packages. dependencies were resolved correctly.
- Somehow found out the /lib32/libbz2.so* is still in the list of preserved libraries, although bzip2 had already been merged with abi_x86_32
- manually deleted the preserved libraries /lib32/libbz2.so* and manually re-emerged bzip2 with abi_x86_32. With the equery command from #3 I saw that bzip installed the libraries to /usr/lib32 instead of /lib32 (where they were installed to by the emul package)

Since then, stuff like imlib2 and freetype fail to compile/link with the errors mentioned in this report.

So it looks like bzip2 installs the libraries in the wrong folder (zlib installs to /lib32/).

...OK, I'll humor you.

Attach config.log from media-libs/freetype-2.5.5 build.

As for bzip2, the files are exactly where they supposed to be.

[Comment 9 jannis 2015-04-08 04:45:43 UTC]

I don't get it: Somehow, the .so files of bzip2 were no longer in /usr/lib32/. I re-emerged bzip2 and afterwards, imlib2 and freetype emerged without a problem. Still don't know how they vanished. I'm sure that I manually deleted them before emerging bzip2.

Nevertheless, problem solved for me and not an issue of mentioned packages/ebuilds. If I manage to find out what deleted the libraries, I'll post here but that probably won't happen.
