Problem with UDF in Linux?

Andrew

I wrote a short and simple UDF for Fluent Windows XP, which works in both serial and parallel processing.

However when I take this simulation into Linux, I keep getting the following error:

Error: /home/fluentuser/UDF.c: line 2: Syntax Error

I run fluent from the /home/fluentuser directory and that is where my cas/data is stored.

By the way, the system has recently had a fresh install so all it has on is Redhat and Fluent 6.2.16

Can anyone help me solve the problem,

Thank you

Andrew

P.S. The code is intepreted and reads as follows:

#include "udf.h"

DEFINE_SDOF_PROPERTIES(store, prop, dt, time, dtime) {

/* Define the mass matrix */

prop[SDOF_MASS] = 5000.;

prop[SDOF_IZZ] = 5000.;
