Hi,

I'm trying to link erl_interface code with non-threaded libs and get the
following:

:~/foo$ make
gcc -fPIC -O2 -fomit-frame-pointer -Wall -g -Wno-pointer-sign -I.
-I/opt/informix/incl/esql -I/tmp/appserv/incl -c arse.c -o ix86/arse.o

I've seen this<http://erlang.org/pipermail/erlang-questions/2003-August/009688.html>post.
 Can anyone tell me what I'm doing wrong?

Thanks in advance,
Paul.
