Hello

What libmysqlclient are you using? I can't seem to find anywhere where 
this log_10_int is declared . It seems to be related to mysql server 
(my_date.h)...

Can you go to /usr/include/mysql a do a grep for this...

There are ok to be Undefined variables in the module.so . They will be 
resolved by the linker when dlopen is called.
