Still not solved: glibc-dbg and insane.bbclass

Still not solved: glibc-dbg and insane.bbclass

[Martin Dietze]

Hi,

 just as my build broke again wiht this issue:
glibc-package.bbclass defines PACKAGES which always contains
glibc-dbg, however the build is without debug symbols for build
time reasons. I guess eventually we'd like to configure from
somewhere whether or not we want debug code and the glibc-dbg
package.

Do we have any "official" mechanism we can use to accomplish
this? Since this is something which *always* breaks builds I'd
think we should do something about this sooner rather than
later.

Cheers,

M'bert

What's exactly breaking? It's perfectly legal (and needed for 
depchains!) for -dbg package to be empty.

This is the QA error I am getting:

| % cat log.qa_package
| wrong architecture, glibc-dbg, /work/mipsel-nylon-linux/glibc-2.3.3-r17/install/glibc-dbg/lib/.debug/ld-2.3.3.so
| wrong architecture, glibc-dbg, /work/mipsel-nylon-linux/glibc-2.3.3-r17/install/glibc-dbg/lib/.debug/libc-2.3.3.so

And this is what the files look like:

| % file  /var/src/OE/tmp/work/mipsel-nylon-linux/glibc-2.3.3-r17/install/glibc-dbg/lib/.debug/ld-2.3.3.so

The files are practicall empty (here libc-2.3.3.so): 

7f 45 4c 46  01 01 01 00  00 00 00 00  00 00 00 00  .ELF............

00 00 00 00  01 00 00 00  00 00 00 00               ............

For whatever reason the build creates those files in .debug
even though the build is performed without debug code.

Ahh, it creates empty .debug/foo.so files. In that case do:

# The files are empty except for the elf header
INSANE_SKIP_glibc-dbg = True

In the offending glibc recipe

Koen

I modified glibc-package.bbclass as you proposed, this is the diff:

The code works well, and if nobody objects, I may commit it later today?
