[gentoo-user] shoutcast problem 64bit gentoo

[Wojtek Dalętka]

Hi,
I've just installed 64bit gentoo on one of these machines:
http://www.ovh.pl/produkty/eg_best_of.xml

Everything is fine. I use hardened profile, Pax, firewall ect, but I've
got problem with ...running a shoutcast server.
I didn't find answer on winamp.com forum and google.

It's exactly the same problem like here:
http://forums.winamp.com/printthread.php?s=48cd69919741579a3c1e4a8b0ac3e38b&threadid=229419

At my server it goes this way:

The problem is that shoutcast is 32 bit and system is 64 bit (and I
think it should be 64 @ this machine).
I've tried to follow these tips from the forum but it didn't help me.

This is a joke, isn't it ??? the error message coming from rc script is a
bit clear IMHO...

64bits system can run either 32 or 64 bits executables. After, it depends
on the libraries used by the 32bits executable, so you have to use a
multilib system.

Well, the error message is clear and that listing from someone's home
directory has me really puzzled -- what's the connection, why present
it?

But maybe he has an /opt he has unmounted since he did "emerge
shoutcast-server-bin"? I do installs the way that I only boot at the
very end of compilations -- when it's really necessary to do so. So
maybe he installed everything -- and forgot /opt from fstab or marked
it not to be mounted automagically?

Or maybe he didn't emerge shoutcast at all, but did something weird
with instructions for some non-gentoo installations?

Anyway, to be of any assistance (and I don't even know or run
shoutcast myself) Mr Daletka should give some more details on how
exactly he got into the situation he is in? How did he install
shoutcast, etc? Why are there binaries in someone's home directory?
(And why is he looking at them instead of the ones that should be
where the init script is looking for?)

It's not a joke.

I'm really not that fresh about installing gentoo and shoutcast. I've
got two production servers (using 32 bit architecture) and this is my
first 64 bit gentoo instalation.
This error is really not caused by a missing sc_serv file....

When using debian, the solution is to install ia-32libs and when using
gentoo it simply doesn't work for me.
That's why I ask here.

Have you emerged emul-linux-x86-baselibs or other precompiled 32-bit
libraries?

I can't help but think that your problem comes from shoutcast doesn't
have full support for 64-bit architectures, so I think you do need
emul-linux-x86-soundlibs and emul-linux-x86-sdl or to recompile
shoutcast from source with the 32-bit glibc. Consider unmasking those
two listed packages, installing and trying again to run the shoutcast
daemon.
