Sometimes mp3 related by installing the package ubuntu-restricted-extras
. This might help you. Many thanks

Let me show you what I have, and maybe you can help me understand
what piece I'm missing.
I have all three of those dev libraries installed:

Apparently my Ubuntu installation already had symbolic links named
with .so which point to the version-specific shared library file
(e.g. libmad.so.0.2.1)

caed reports in the system log that it has the MAD decoding
capabilities during startup
$ grep -A2 -B2 -i caed.*mad /var/log/syslog |sed -e 's/.*u-11//'
ripcd: started

caed: Found MAD decoder library, MPEG L2 decoding supported

Since that message is logged from within MainObject::LoadMad, I can
tell that libmad.so was successfully loaded during caed's startup.
It was a little bit trickier, but I was able to verify that the CGI
program does successfully load libmad. I found this out by getting a
fresh apache2 environment, then attaching strace[1] to every child
process and then performing an rdimport of an mp3 file. I can see
from the strace's output that it loads libmad:
31590 open("/usr/lib/i386-linux-gnu/libmad.so", O_RDONLY|O_CLOEXEC) = 5
31590 read(5,
"\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0000\20\0\0004\0\0\0"...,

MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 5, 0x15) = 0x1837000
31590 close(5)
I must still be missing something, but I can't tell what. Is there
any other place where I have to make Rivendell aware that it has mp3
decoding capabilities?
Thanks again for your help and insight,

[1] For anyone trying to reproduce that test, here's the full command:
sudo service apache2 restart ; sudo rm -v /tmp/apache2.strace.* ;
for pid in `pidof apache2` ; do sudo strace -f -p$pid
-o/tmp/apache2.strace.$pid & done ; sleep 3; rdimport --log-mode
TEST /tmp/your-test-file.mp3 ; sudo killall strace ; grep libmad
/tmp/*strace*

Hi Nate,
Rivendell uses dlopen to find libmad.so, libmp3lame.so and
libtwolame.so.
On Debian/Ubuntu systems, these libraries are available as
libmad.so.0,
libmp3lame.so.0 and libtwolame.so.0.
You can either :
* create manual links
* install the associated libXYZ-dev packages (with provided
link)
* apply the same patch as the debian packaging does [0]
Or more simply use the debian/ubuntu packages :)
0.
