I'm trying to recompile my udf on linux mandrake.
Like this
gcc -c -w -fPIC udf.c
ld udf.o -o udf -shared -lgds

after that I moved udf to /opt/interbase/UDF

I still had the blr error. So in the pass someone showed me a linux command
and I don't remember it. It's a command for display the information of a
library. Is there somebody who know that command

I hope my explanation was clear
