Re: how to debug and use user defined functions?

3 Jul 2013

      Hi Stefan,

Thanks very much, i entered into gdb debug and set a breakpoint at
binaryCopy,

(gdb) b binaryCopy
Note: breakpoint 1 (permanent) also set at pc 0x7fffee687f2a.
Breakpoint 2 at 0x7fffee687f2a: file svom.c, line 36.

but how could i debug my defined function and step into it, how to enter my
function?

Best regards,
Meng

turn "lib_svom" into "lib__svom" (mind the double '_' as with udf & ssdb
--- exactly the name difference you noticed and were wondering about ...)
and things should work ... --- you also need to start with a newly created
virgin empty database to ensure that all scripts in
libdir/monetdb5/createdb (i.e., including your 81_svom.sql) are executed
(they are not expected to be idempotent and thus only executed with the
first server start on a new virgin empty DB) ...

There is no function "reverse" in UDF.
What does `mserver5` say?
Can you share your Makefile.ag?
