[Comment 1 Mr. Bones. (RETIRED) 2005-03-31 10:48:32 UTC]

can you try it with gcc-3.3 and see if it's a gcc-3.4 issue please?

[Comment 2 Michael Hill 2005-04-01 13:49:00 UTC]

Good call, Mr. Bones.  It compiled fine with i686-pc-linux-gnu-3.3.5 .

Should this be assigned to the gcc team?

[Comment 3 Michael Hill 2005-04-01 13:51:06 UTC]

Oh, and is there a way to tell emerge to use gcc-3.3 for this even if gcc-config has it set to 3.4 ?

[Comment 4 Mr. Bones. (RETIRED) 2005-04-01 14:03:01 UTC]

no, the toolchain guys probably aren't interested since it's likely to be an upstream bug.  On the other hand, if it works with different versions of gcc-3.4 they *might* be.

There's no way to have portage use a particular version of gcc to compile specific packages.  You'd need to use gcc-config to set it to 3.3, merge the package, then use gcc-config to set it back to 3.4.

[Comment 5 Francesco 2005-04-16 06:23:39 UTC]

Can't compile it (same error!) with 3.3.5 and 3.4.3 on a machine. On other one it's all ok. No idea what could be wrong.

[Comment 6 Mr. Bones. (RETIRED) 2005-04-16 11:20:29 UTC]

you can try "emerge -ev scummvm"

[Comment 7 Mr. Bones. (RETIRED) 2005-05-25 17:01:00 UTC]

Is this still an issue?  I've never been able to reproduce it.

[Comment 8 Michael Hill 2005-05-29 22:14:24 UTC]

I'll have to get back to you on that...  I tried re-emerging scummvm, but with
the same version of gcc, so (duh!) I got the same error.  Tried unmasking and
emerging gcc-3.4.3.20050110-r2, but ran out of space.  D'oh.  So I'll have to
free up some space and try building it again, and then try scummvm.

[Comment 9 Michael Hill 2005-05-30 09:31:11 UTC]

Okay, building with gcc-3.4.3-20050110 yields the same error.  I don't know what
the right course of action is for this bug, but I do have scummvm-0.7.1 built,
so I guess it's not as critical.
