MySQL-3.23.32
FreeBSD 4.2-RELEASE
problem:
==========================================================
MySQL documentation:
16.1 Adding a New User-definable Function
[...]
The MySQL source
distribution includes a file `sql/udf_example.cc' that defines 5 new
functions. Consult this file to see how UDF calling conventions work.
[...]
==========================================================
sql/udf_example.cc:
** A dynamicly loadable file should be compiled sharable
** (something like: gcc -shared -o udf_example.so myfunc.cc).
** You can easily get all switches right by doing:
** cd sql ; make udf_example.o
** Take the compile line that make writes, remove the '-c' near the end of
** the line and add -o udf_example.so to the end of the compile line.
** The resulting library (udf_example.so) should be copied to some dir
** searched by ld. (/usr/lib ?)
==========================================================
bash-2.04$ make udf_example.o

Can somebody tell me where source of the problem can be?
