Re: dbd mysql segmentation fault in 2.2.6

FINALLY,  I found the problem and it was so simple.....I could shoot 

myself.  I forgot DBDPersist off in the conf file.  This was causing the 

seg faults.

Daniel,

Your slackware 12,  you are installing apache from source from 

httpd.apache.org ? if so ls /var/log/packages/http*

if it returns a package then   "removepkg httpd "

Then reinstall from source again, I have done a gazillion slackware 11 

and 12's with apache2 and mysql and none have ever shown me the 

problem you are having. From our previous conversations, I know you 

know the correct procedure for installing it all, theres just somthing 

there thats interupting it.

If none of that applies, remove all dbd global options apart from the 

DBDParams, then add "DBDPersist off" and  "DBDriver mysql"

and try that

Subject: Re:  dbd mysql segmentation fault in 2.2.6

I have. I do the ldd on the httpd and it shows the mysql client lib in
the list. I still get the segmentation fault as soon as I put the
DBDriver mysql command into the httpd.conf file. I have installed the

gdb but I am unsure exactly how to get it to produce the results I 

need.

the mysql-client from `ldd httpd` might be from the option
--with-mysql=/usr/lib/mysql you put when compiling.

In my working installation libmysql-client is from `ldd
libaprutil-x.x`. But I didnt use the included apr. You might try
installing apr-util before hand to see if it makes any difference for
you.
