Description shrevz 2006-03-17 20:59:39 UTC
Summary: 
I've been having trouble with building a52dec. It seems there are two issues:
(1) A hidden dependency on =automake-1.4
(2) Build fails with -pipe (or maybe some other opt. flags)
emerging automake-wrapper and removing optimization fixed the problem

Details:
Both  media-libs/a52dec-0.7.4-r5 media-libs/a52dec-0.7.4-r3
failed to build before I installed automake-wrapper. I had automake 1.9, and the build failed with an aclocal error. The log showed they were trying to execute /usr/bin/aclocal-1.4

after emerge-ing automake-wrapper the r5 build failed again on:

 i686-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I. -I../include -I../include -I../include -march=pentium4 -pipe -funroll-loops -fstrength-reduce -frerun-loop-opt -O3 -fomit-frame-pointer -mcpu=pentiumpro -march=pentium4 -pipe -funroll-loops -fstrength-reduce -frerun-loop-opt -O3 -fomit-frame-pointer -mcpu=pentiumpro -Wp,-MD,.deps/imdct.pp -c imdct.c -o imdct.o >/dev/null 2>&1
{standard input}: Assembler messages:
{standard input}:3622: Error: suffix or operands invalid for `movd'

My make.conf is set with:
CFLAGS="-march=pentium4 -O3 -pipe -funroll-loops -fstrength-reduce -frerun-loop-opt"

Changing to CFLAGS="-march=pentium4" fixed the problem.

my gcc version is:
gcc (GCC) 3.2.3 20030422 (Gentoo Linux 1.4 3.2.3-r1, propolice)

There's no such thing, automake-wrapper (and so all slots of automake) are part of system target and must be installed on every Gentoo system. Not optional.

Your gcc is *way* outdated and unsupported. Reopen if you can reproduce this w/ gcc-3.4.5 and sane C[XX]FLAGS (like -march=pentium4 -O2 -pipe).
