Bug 88022 – Link time errors: `.LAAAA' referenced in section `.rodata' of BBBB.o: defined in discarded section `.gnu.linkonce.t.CCCC' of DDDD.o with recent gcc (3.4.3) and binutils (2.15.92.0.2)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Ed Catmur 2005-04-05 04:15:14 UTC]

When compiling e.g. LyX, at link time hundreds of errors along the lines of:

`.LAAAA' referenced in section `.rodata' of BBBB.o: defined in discarded section `.gnu.linkonce.t.CCCC' of DDDD.o

This is known upstream, at
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16625

This is NOT a bug in the program being compiled, but in gcc/binutils interaction, see e.g. the testcase at
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16849

I have tried applying the patch at 
http://gcc.gnu.org/ml/gcc-patches/2004-08/msg00653.html
and can confirm that it 
a) fixes the testcase at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16849
b) allows LyX to compile/link.

I therefore suggest that the patch at http://gcc.gnu.org/ml/gcc-patches/2004-08/msg00653.html should be applied. 
It needs a little massaging to apply cleanly to 3.4.3.20050110-r1 sources.

Created attachment 55345 [details, diff]
3.4.3/jumptables-fix.patch

Patch (to gcc) from http://gcc.gnu.org/ml/gcc-patches/2004-08/msg00653.html
Minor edit to apply cleanly to 3.4.3.20050110 sources.

although that doesnt appear to the final patch, it does seem to be the smallest and can probably be substituted until 3.4.4 when the real fix is integrated upstream

what version of binutils did you test with ?

[Comment 3 Ed Catmur 2005-04-06 01:10:57 UTC]

binutils: 2.15.92.0.2-r7
gcc: 3.4.3.20050110-r1

[Comment 4 SpanKY 2005-04-07 19:48:54 UTC]

ok, this also resolves our boost issues we've been having lately :)

added to 3.4.3.20050110-r2
