asterisk users - Jan 2006 - problems with installing app_odbcexec into dialplan

Hi all,

I am trying to install the ODBCexec and ODBCquery functions into my
dialplan but I'm having difficulties in the installation of
app_odbcexec.c itself. I'm using Asterisk 1.2.1 and I've downloaded and
installed unixODBC. But when I try to run "make" after editing
Makefile
and copying the app_odbcexec.c to my asterisk/apps location, this is 
the
output I get:

cc -fPIC   -c -o app_odbcexec.o app_odbcexec.c

                from /usr/include/asterisk/chanvars.h:26,

                from /usr/include/asterisk/file.h:30,
                from app_odbcexec.c:22:

I hope someone can help me on this. I've tried googling this but 
nothing
has materialised.

Thanks - Pravin
