RE: [Serusers] could not open module mysql.soI 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 

  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
