New subject: [Serusers] could not open module mysql.so

13 Sep 2004

      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
Regards
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.
Zeus

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.12.0.0*
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 :
