Bug 7573 – smpeg-0.4.4-r4 doesn't build well with gcc 3.2

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description jawed hancali 2002-09-06 05:41:43 UTC]

if you try to build something with libsmpeg-0.4.so.0 you get some unresolved
symbols (ldd -r /usr/lib/libsmpeg-0.4.so.0 will show the unresolved symbols)

this is because libsmpeg-0.4.so.0 isn't linked with libgcc_s
the problem is resolved if we link it with libstdc++ instead of libsupc++

so here is a patch to apply instead of the gcc3.1 one

Carpaski,

     Getting feedback from my bug users that this patch resolves their sdl 
issues. Any chance on the patch being included in portage?

smpeg ebuild that also works for gcc3.2

[1]
Save the patch ( http://bugs.gentoo.org/showattachment.cgi?attach_id=3703 ) as
/usr/portage/media-libs/smpeg/files/smpeg-0.4.4-gcc-3.2.patch

[2]
Place this submitted ebuild in /usr/portage/media-libs/smpeg/files/ to
overwrite the old one.

[3]
To get frozen-bubble work:
emerge libsdl smpeg sdl-mixer frozen-bubble

(so you'll need to rebuild whatever needs smpeg to get something working)

It works here.. 
Have fun.

PS: Have a look at the code, it's probably not that good and all of that, and
it probably should be r5. Use it if you want to, change it if you like :)

[Comment 4 Vince Verleye 2002-09-25 17:58:03 UTC]

Should ofcourse be:

[2]
Place this submitted ebuild as
/usr/portage/media-libs/smpeg/smpeg-0.4.4-r4.ebuild to
overwrite the old one.
-------------------------------------8<------------------------------------

Sorry about that.

emerge using your patch and new ebuild still does not work

[Comment 7 Vince Verleye 2002-10-01 09:21:57 UTC]

Andreas: 

That doesn't seem related to this bug though. Post on http://forums.gentoo.org
if you haven't already, perhaps someone can come up with a solution to that.

[Comment 8 Andreas Kotowicz 2002-10-07 11:31:14 UTC]

Vince: you're right. there was a broken link causing this problem

[Comment 9 Chris Williams 2003-01-07 00:38:55 UTC]

This problem of unresolved symbols does not seem to hold under GCC 3.2.1.  On my
machine _without_ the Bug 7573 patch:

So all is well.  The library shows none of the unresolved symbols the bug talks of.

i was able to build it with gcc-3.2.3

[Comment 11 Heinrich Wendel (RETIRED) 2003-07-26 04:53:38 UTC]

seems to work -> close

[Comment 13 SpanKY 2003-09-23 20:32:31 UTC]

your problem is unrelated to a gcc bug, you're probably missing a few sdl libraries

make a new bug if you cant track it down
