Bug 76155 – scummvm-0.7.0 fails to build on athlon-xp with 'internal compiler error'.

• Status: RESOLVED INVALID

scummvm-0.7.0 won't build on Athlon XP platform with GCC 3.3.4.

I attract your attention to the particular error: "internal compiler error", and in what kind of function it's happening: Detect3DNow().
I assume this is an architecture-specific bug that doesn't happen everywhere.

This may be a GCC bug *OR* a problem in the way my own GCC was compiled.
Here are the USE flags my GCC was compiled with: +X -bootstrap -build -debug -fortran -gcj -hardened -multilib +nls +objc +pic -static (-uclibc)


Temporary workaround:
Disable MT32 emulation (configure option --disable-mt32emu) on the affected platforms.

Reproducible: Always
Steps to Reproduce:
1. Find Athlon XP box
2. emerge =games-engines/scummvm-0.7.0

[Comment 2 Danny van Dyk (RETIRED) 2004-12-30 12:15:09 UTC]

Mr_Bones_: Why has amd64 been added to the CC list ?

[Comment 3 Chris Gianelloni (RETIRED) 2004-12-30 12:32:22 UTC]

Accident... we hadn't given Mr_Bones_ his medication before we let him out of his cage... sincerest apologies.

[Comment 4 Mr. Bones. (RETIRED) 2004-12-30 12:54:06 UTC]

Doh.

Anyhow, Sundance, try it with CFLAGS and CXXFLAGS set to "-pipe" and see if that makes a difference for you.  Builds fine here.

I had almost the same problem. Same error but on the next file to be compiled:

g++ -Wp,-MMD,"backends/midi/mt32/.deps/partial.d",-MQ,"backends/midi/mt32/partial.o",-MP -Wall -O3 -march=athlon-xp -pipe -fomit-frame-pointer -fPIC -DPIC -O3 -march=athlon-xp -pipe -fomit-frame-pointer -fPIC -DPIC   -ansi -W -Wno-unused-parameter -O -Wuninitialized -Wno-long-long -Wno-multichar -Wno-unknown-pragmas -pedantic -Wpointer-arith -Wcast-qual -Wconversion -Wshadow -Wimplicit -Wundef -Wnon-virtual-dtor -Wno-reorder -Wwrite-strings -fcheck-new -Wctor-dtor-privacy  -DHAVE_CONFIG_H -DUNIX -DDISABLE_SAGA -DDISABLE_KYRA -I. -I. -I./common -I./backends/midi/mt32        -I/usr/include/SDL -D_REENTRANT -Itest/cxxtest -c backends/midi/mt32/partial.cpp -o backends/midi/mt32/partial.o

backends/midi/mt32/i386.cpp:466: internal compiler error: in

My CFLAGS and CXXFLAGS were both set to: 
   -O3 -march=athlon-xp -pipe -fomit-frame-pointer -fPIC -DPIC

I tried the following as suggested by Mr. Bones and it compiled correctly:
   CFLAGS=-pipe CXXFLAGS=-pipe emerge games-engines/scummvm

[Comment 6 Stian Skjelstad 2004-12-31 12:51:38 UTC]

Is this an gcc upstream bug or a gentoo patch that makes this problem?

[Comment 7 Sundance 2005-01-04 20:29:46 UTC]

Mr. Bones:

Thank you for your answer. I've built ScummVM-0.7.0 with CFLAGS set to "-pipe", and it indeed works. I've hunted down the flag that causes it to fail, and it seems to be "-fPIC". I tried with and without "-march=athlon-xp", and it doesn't affect the end result.

I don't know if this is a GCC bug or a ScummVM bug, but you will probably want to inform the GCC guys nonetheless, since it failed with an 'internal compiler error'. In the meanwhile, the ScummVM ebuild can be fixed by filtering out the -fPIC flag, I suppose.

[Comment 8 Mr. Bones. (RETIRED) 2005-01-22 22:43:41 UTC]

You shouldn't have -fPIC in your global CFLAGS anyhow so I'm going to go ahead and mark this INVALID.  Glad it's working for you.

[Comment 9 Sundance 2005-01-23 05:00:42 UTC]

Isn't -fPIC mandatory to make prelink work though?

[Comment 10 Chris Gianelloni (RETIRED) 2005-01-23 08:16:36 UTC]

Not exactly, since most stuff builds properly.  It really can break stuff to force -fPIC in CFLAGS, as there are certain things that won't build with it.

[Comment 11 Sundance 2005-01-23 09:18:38 UTC]

Thank you for the kind answer to this off-topic question. :) I've removed -fPIC from my CFLAGS. There seems to be a USE flag to handle this option nowadays, anyway, so it's all good. Thanks again!
