Description of problem:
db4 that is in RHL 9 cause DCTC (a Direct Connect clone, you can get
it from: http://ac2i.homelinux.com/dctc/) to crash.

When i run DCTC i've got following messages:
[marcin@drosera i386]$ dctc -g 192.168.2.36
INFO ] ""Direct Connect Text Client v0.85.7|

file exists.
current sema found.
DCTC: db_appinit, open /home/marcin/.dctc/bDB fails: Function not
implemented

Other users of RHL 9 have the same problem, but if they install db4
from RHL 8.0, or recompile db4 from source DCTC work fine.

Is this build problem or install problem?

If build, you need to fix your build for db-4.2.52.

If install, then you need to install compat-db-4.1.25.

Which is it?

Comment 2 Jeff Johnson 2003-12-22 22:43:38 UTC

Hmmm, sorry, it's the same issue with db-4.1.25 in RHL 9
as well. If build, you need to fix your build, if install,
you need cpmpat-db-4.0.14.

Comment 3 Marcin Garski 2003-12-23 00:17:16 UTC

It isn't build problem nor install.
I can compile and install DCTC without any errors, warnings and problems.
The problem occur when i'am try to run DCTC (it show messages that i
mention already "DCTC: db_appinit, open /home/marcin/.dctc/bDB fails:
Function not implemented").
This problem appear only in RHL 9 with shipped db4 RPM.

Beside in RHL 9 the only available version of db4 is db4-4.0.14-20.

Comment 4 Jeff Johnson 2003-12-23 02:03:38 UTC

"Function not implemented" smells a lot like
you are running a non-nptl kernel and hence missing
certain (optional) pthread routines.

What kernel? What glibc? Where did they come from?

Reading the bugs indicates that a recompile of
db4 "works". That's prolly all that can be done
for an unsupported package like dctc. Have you tried
recompiling db4 from the src.rpm?

Comment 5 Marcin Garski 2003-12-23 14:23:36 UTC

I'm running on home-made 2.4.22 kernel (vanilla + XFS), glibc is
2.3.2-27.9.7 (from RHL 9 update).

I've found what cause this problem, you are right that is NPTL :)
If i back to distro kernel (with NPTL) without changing db4, or
recompile db4 from src.rpm without --enable-posixmutexes (i've comment
this line) but with new kernel 2.4.22 (without NPTL) DCTC works fine.

Thanks for help (and aiming me at NPTL) !!!
