Hi,

when interacting with MySQL database I should invoke mysql_library_init
() function first. GNADE does not have it implemented so I tried to do
this on my own:

      function mysql_library_init (
         argc     : int;
         argv     : chars_ptr;
         groups   : chars_ptr
      ) return int;
      pragma Import (C, mysql_library_init, "mysql_library_init");

used as:
     ... := mysql_library_init (0, Null_Ptr, Null_Ptr);

I build my program with -I/usr/include/mysql -L/usr/lib64/mysql -
lmysqlcient and get:
     undefined reference to `mysql_library_init'
     collect2: ld returned 1 exit status
     gnatlink: error when calling /usr/bin/gcc
     gnatmake: *** link failed.

I tested my build setting with mysql_init() and mysql_close() and it
is fine, I cannot get mysql_library_init() and mysql_library_end
working.

Simple C application with these functions works.

Any ideas?
