Hi, everyone,
As said in documentation, there is no need to build MySQL with
-rdynamic: "If you want to use an UDF that needs to access symbols from
mysqld (like the methaphone example in `sql/udf_example.cc' that uses
default_charset_info), you must link the program with -rdynamic (see man
dlopen). "
I need a simple udf, to convert string from one format to
another like "09:32:52.370 UTC Wed Nov 12 2003" into "2003-11-12
09:32:52". To let it insert into date field. Can I write such udf
without using any "specific" symbols, that could compile in MySQL
-with-mysql-ldflags=-all-static?
I've written just simple udf without using anything and it realy
does nothing (it is just function declarations and empty dunction
bodies). I compiled it succesfully, and put "udf_test.so" into /usr/lib.
But when I tried load it into MySQL using:
> CREATE myudftest RETURNS STRING SONAME "udf_test.so";
the result was error 2013 - Lost connection to MySQL server
during query.
Can anyone help me in this situation? I dont want to recompile
MySQL with -rdynamic because I need only one simple udf, but I need it.
Ho to make this with staticaly compiled MySQL? Has anyone already made
this?
Thanks,
Best regards to all,
Arunas
