UDF: can't resolve symbol

[Jochen Dolze]

i'm using mysql-3.22.16a-gamma on linux-2.1.111
(libc.so.5.4.17,libstdc++.so.27.2.1) with
linuxthreads-0.6.

i compiled udf_example.cc with

  c++ -Wall -shared -DMYSQL_SERVER 
  -DDEFAULT_MYSQL_HOME="\"/usr/local/mysql\""
  -DDATADIR="\"/usr/local/mysql/var\""
  -DSHAREDIR="\"/usr/local/mysql/share/mysql\"" -DHAVE_CONFIG_H
  -I./../include -I./../regex -I. -I../include -I.. -I.  -O  -DDBUG_OFF -o
  libudf_example.so

after that i moved libudf_example.so to /usr/local/mysql/lib and ldconfig
-v shows:

  ldconfig: version 1.8.5  
  /usr/local/mysql/lib:
	libmysqlclient.so.6 => libmysqlclient.so.6.0.0
	libudf_example.so => libudf_example.so

and, ldd libudf_example.so shows:

  ./libudf_example.so => ./libudf_example.so
     libc.so.5 => /lib/libc.so.5.4.17
     libstdc++.so.27 => /usr/lib/libstdc++.so.27.2.1
     libm.so.5 => /lib/libm.so.5.0.6

but, after CREATE FUNCTION lookup RETURNS STRING SONAME "udf_example.so" i
get

  ERROR 1126: Can't open shared library 'udf_example.so' (errno: 22 Unable
  to resolve symbol)

And the log says:

  /usr/local/mysql/libexec/mysqld: can't resolve symbol 'ctype_latin1'
  /usr/local/mysql/libexec/mysqld: can't resolve symbol 'to_upper_latin1'

Where are ctype_latin1 and to_upper_latin1 defined??? What's wrong?

Ciao
