From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; pl-PL; rv:1.4.1) Gecko/20031010 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| hubip: 192.168.2.36 hubport: 411 Using 192.168.35.152 as localhost IP.

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. You can find more information under this addresses: http://brainz.servebeer.com/phpBB2/viewtopic.php?t=286 http://brainz.servebeer.com/phpBB2/viewtopic.php?t=179 http://brainz.servebeer.com/phpBB2/viewtopic.php?t=165 Version-Release number of selected component (if applicable): db4-4.0.14-20 How reproducible: Always Steps to Reproduce: 1. Download DCTC source 2. Compile it 3. Run DCTC 4. Watch the errors Actual Results: DCTC crash Expected Results: DCTC should be working :) Additional info:
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?
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.
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.
"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?
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) !!!
