I tried to upload the two files several times, but it did'n work : |

[Comment 2 Javier Valencia 2004-11-26 05:08:07 UTC]

You have gcc-3.3.3 (me too) and libmpeg2 searches for gcc-3.3.2 libs (in my situation):

gcc -Wall -march=i686 -mcpu=i686 -pipe -O3 -fomit-frame-pointer -fno-common -mcpu=pentiumpro -I/usr/X11R6/include -I/usr/include/SDL -D_REENTRANT -o extract_mpeg2 extract_mpeg2.o getopt.o 
/bin/sh ../libtool --mode=link gcc -Wall -march=i686 -mcpu=i686  -pipe -O3 -fomit-frame-pointer -fno-common -mcpu=pentiumpro -I/usr/X11R6/include -I/usr/include/SDL -D_REENTRANT    -o corrupt_mpeg2  corrupt_mpeg2.o getopt.o  
libtool: link: cannot find the library `/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.2/libstdc++.la'
make[1]: *** [mpeg2dec] Error 1
make[1]: *** Waiting for unfinished jobs....

I have gcc version 3.3.3 20040412 (Gentoo Linux 3.3.3-r6, ssp-3.3.2-2, pie-8.7.6)

[Comment 3 Javier Valencia 2004-11-26 05:28:25 UTC]

I made a link from 3.3.3 dir to 3.3.2 and worked for me. Also, 'grep -R "3.3.2" *' in the mpeg-0.4.0b directory didn't give any result. The same in /etc, but libmpeg always try to use 3.3.2 libs.

Javier:

the following command will fix your problem:

'# fix_libtool_files.sh 3.3.2'

Christoph Fürstaller:

do you also have problems compiling it when you set your CFLAGS to "-O2 -march=pentium3 -pipe" ?

[Comment 7 Jan Brinkmann (RETIRED) 2005-03-12 17:33:07 UTC]

feel free to reopen if this is still an issue if you compile things with sane cflags.
