Very Computer

Hi everyone,

When trying to compile some libs and programs today I got a very rude
awakening:

gcc -g -O2 -Wall -fomit-frame-pointer -funroll-loops -g -O2 -Wall
-fomit-frame-pointer -funroll-loops -march=i586 -mcpu=pentiumpro -o
.libs/ogle_audio audio_out.o parse_config.o audio_config.o conversion.o
audio_play.o decode.o decode_a52.o decode_lpcm.o decode_mpeg.o
../common/libcommon.a ../ogle/.libs/libmsgevents.so
../libogleao/.libs/libogleao.al /usr/lib/libasound.so -ldl -lpthread
-L/usr/local/lib /usr/local/lib/liba52.a /usr/lib/libmad.so -L/usr/lib
/usr/lib/libxml2.so -L/usr/X11R6/lib -lz -lm -lrt -Wl,--rpath
-Wl,/usr/local/lib/ogle -Wl,--rpath -Wl,/usr/local/lib
../libogleao/.libs/libogleao.al(alsa_audio.lo): In function `alsa_init':
/home/jbailey/src/ogle-0.8.5/libogleao/alsa_audio.c:145: undefined
reference to `assert'
/home/jbailey/src/ogle-0.8.5/libogleao/alsa_audio.c:146: undefined
reference to `assert'
collect2: ld returned 1 exit status
make[1]: *** [ogle_audio] Error 1
make[1]: Leaving directory `/home/jbailey/src/ogle-0.8.5/ac3'
make: *** [all-recursive] Error 1

Yes, I realize this version of ogle I'm trying to compile is quite old;
however, it works, and I am happy with that. I just want it to compile!
Is there a specific -L or -l flag I should add to my $CFLAGS when I
run the configure script (or when editing makefiles if necessary)?

In case this makes a difference:

The box is running SuSE 8.1 Professional.

Any help is greatly appreciated! Also, I apologize if I've posted to
the wrong group. If I have, please inform me which groups I should post
this kind of problem to and I will post to those groups in the future.

According to my documentation, assert is a macro. You might
check alsa_audio.c to see if it includes 'assert.h'

Thanks for the tip. I checked (it was not included), and even went to
the extreme of including 'assert.h' in all 16 source files for the
application, it still will not compile. For good measure, I even did
'make clean' and ran './configure' again. Oddly enough, however, I
successfully compiled this same version of ogle on Mandrake 8.1 at
least twice. That was a long time ago, though.

I seem to remember that gcc-3.2 had trouble with one of
their flags, maybe -Wall, that would prevent proper
compilation in some cases. I still use 2.95, so I didn't
pay attention, and I may be in error, but as a last resort,
try eliminating the -Wall from the makefiles. If that
fails, try upgrading to the latest gcc release. If you were
successful before, I suspect some type of obscure error in
the compiler that prevents proper macro expansion.

When trying to get gcc-3.3 to compile I ran into the exact same
problem, "undefined reference to 'assert'" and decided to do some
investigating that hadn't occurred to me before:

/usr/include/assert.h
/usr/lib/bcc/include/assert.h
/usr/local/include/assert.h

snippet of /usr/local/include/assert.h:

/* libFLAC - Free Lossless Audio Codec library
* Copyright (C) 2001,2002 Josh Coalson
*

Since I knew that /usr/local/include gets checked for headers before
/usr/include, I renamed /usr/local/include/assert.h to something else
and then tried compiling ogle again. It compiled and linked
flawlessly.

Thanks for the help!
