Strange but true!
(I am using mysql 5)
I had tried previously to link the two files in /usr/lib - but without any luck.
After using strace as directed the output showed no association between libmysqlclient.so.12 and libmysqlclent.so.10 in /usr/lib.
However - when I re-linked the two files in /usr/lib after running strace - everything 'magically' started working - and so ended 5 days of frustration!
Thanks for all your help
Best Regards
Paul

If recompilation if done and dont work you can use strace to see where are SER searching libmysqlclient:
strace ser -D 2>execlog
grep "libmysqlclient" execlog
Probably SER try to open /lib/libmysqlclient.so.12 and your mysql installation put the library under /usr/lib/mysql

I think that this is due to mysql upgrade from 3.23 to 4.
Try recompiling the ser mysql module

Gwen,
Where did you make the ln -s libmysqlclient.so.12 libmysqlclient.so.10?
I have the same problem - and have tried to link the old embedded reference but without success

Paul

I finally found the solution...
First, I don't know why but I had a strange link file (libmysqlclient.so.10) in my folder /usr/local/lib/ser/modules. I deleted it and then I got the following result of the command "ldd mysql.so" : linux-gate.so.1 => (0xffffe000) libmysqlclient.so.10 => /usr/lib/libmysqlclient.so.10 (0x40028000) libz.so.1 => /usr/lib/libz.so.1 (0x4005f000) libc.so.6 => /lib/tls/libc.so.6 (0x40070000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x401b8000) libnsl.so.1 => /lib/libnsl.so.1 (0x401e5000) libm.so.6 => /lib/tls/libm.so.6 (0x401f8000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
Now, I have the same result than Zeus but I didn't have any /usr/lib/libmysqlclient.so.10...
When I installed the libmysql12, I obtained new files in /usr/lib/ (libmysqlclient.so.12 and some others). When SER try to load mysql.so, it looks for the library libmysqlclient.so.10 and obviously can't find it. So I made a link with the following command : ln -s libmysqlclient.so.12 libmysqlclient.so.10
And now, SER can load the mysql module !!
Thanks for your help Zeus !! Bye, Gwen
Hi Zeus and other serusers,
The mysql.so file is the one I got with SER.(ser-0.8.12_linux_i386.tar.gz,
if I remember...).
Could you tell me what output you get with this command : # ldconfig -v |grep mysql ldconfig: Path `/usr/lib' given more than once libmysqlclient_r.so.12 -> libmysqlclient_r.so.12.0.0 libmysqlclient.so.12 -> libmysqlclient.so.12.0.0 libmysqlclient.so.10 -> libmysqlclient.so.10
Thanks, Gwen
Gwen,
There is something wrong with your mysql.so file. Did you compile it yourself or download it somewhere? It doesn't look like mysql library is linked into it. My ldd output is like this:
sip:/usr/local/lib/ser/modules> ldd mysql.so libmysqlclient.so.10 => /usr/lib/libmysqlclient.so.10 (0x00bbb000) libz.so.1 => /usr/lib/libz.so.1 (0x00abf000) libc.so.6 => /lib/tls/libc.so.6 (0x003f3000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x0056a000) libnsl.so.1 => /lib/libnsl.so.1 (0x0029e000) libm.so.6 => /lib/tls/libm.so.6 (0x00111000) libnss_files.so.2 => /lib/libnss_files.so.2 (0x00a7d000) libnss_dns.so.2 => /lib/libnss_dns.so.2 (0x006dd000) libresolv.so.2 => /lib/libresolv.so.2 (0x00967000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x0036b000)
Note the first line states that mysql.so should dynamically load the mysql library from /usr/lib/libmysqlclient.so.10. It is absent from your output. Either recompile the module or download another copy from the FTP server.

Gwen,
It appears that your mysql.so is not link properly with the mysql library. Send the following output to the list. It may give us more insight on your problem.
root# ldd /usr/local/lib/ser/modules/mysql.so root# cat /etc/ld.conf

Hi,
I checked my MySQL-client package. So I installed MySQL-client-4.0.20-0.i386.rpm. I also had to install the package libmysql12. But, I still have the same problem with the
load of mysql
module...
I the folder /usr/lib, new files appeared : libmysqlclient_r.so.12@ libmysqlclient_r.so.12.0.0* libmysqlclient.so.10* libmysqlclient.so.12@ libmysqlclient.so.12.0.0*
What 'libmysqlclient' files do you have in your folder
/usr/lib and
/usr/local/lib/ser/modules/ ??
When I use "/usr/local/sbin/ser -c", the message of the error is a bit different : 0(2570) loading module /usr/local/lib/ser/modules/mysql.so 0(2570) ERROR: load_module: could not open module </usr/local/lib/ser/modules/mysql.so>: /usr/local/lib/ser/modules/mysql.so: undefined symbol: mysql_field_count 0(2570) parse error (14,13-49): failed to load module # ...bla bla... don't mind ERROR: bad config file (1 errors)
