There is an unofficial patch to make bahamut compile under redhat9 and
gcc3.x, it is unsupported but it does work.

This patch is intended to fix _res linking failures for bahamut 1.4.35-36
with
newer threaded versions of glibc. Place this file in bahamut-release and
run:

patch -p0 < resfix.patch

I've got the most recent version of bahamut, 1.4.36,
and I *still* get this error. In addition, your patch doesn't work, it gives me:

patch: **** malformed patch at line 5: #define RES_TIMEOUT 5 /* min. seconds between retries */

when I try to apply it......... what am I doing wrong?

Strange... you're running gcc 3+ along with it's libraries correct?

Try the patch found here: https://secure.alastria.net/resfix.patch on Bahamut 1.4.35... of course, typing "patch < resfix.patch" from within the include directory.

Remember that to change the network name in version 1.4.36, you have to go in s_user.c, to change the "Welcome to the DALnet IRC Network" its located in s_err.c... the rest is in config.h...

if operserv and helpserv is on services you also need to change it in config.h from STATS_NAME to SERVICES_NAME for those two to work with /os and /hs.

also I dont believe bahamut will run on redhat 9... it works best on freebsd... actually... freebsd is the best for IRCds in the first place

anope's threading support shows as 1 process on freebsd and as multiple processes on linux...

*BSD is the way to go..

Recompile your IRCd.

type: make clean ; make ; make install

that should do it, if you changed the files correctly.

Because all DALnet servers are on FreeBSD, the IRCd was written specificlly for FreeBSD.

_res patch reviewed by me (applied manually tha patch posted above, so it cleanly applies):

While into source directory, make sure to use
patch -p1 < bahamut-1.4.35-_res-fix.diff to apply the patch.

At least it compiles cleanly after applying too!.. Not tested actually running the server itself. But it's worth a try!
