Help!! I'm trying to interpret a source file written in C, and I get the following error message:

cpp -IC:\Fluent.Inc\fluent6.1.22/src -IC:\Fluent.Inc\fluent6.1.22/cortex/src -IC:\Fluent.Inc\fluent6.1.22/client/src -IC:\Fluent.Inc\fluent6.1.22/multiport/src -I. -DUDFCONFIG_H="<udfconfig.h>" H:\Final tube model\unsteady.c

Error: H:\Final tube model\unsteady.c: line 1: parse error.

The source file i'm attempting to interpret has a .c extension, i don't know what to do, please help!

What's more to that, i'm alternatively trying to Compile (instead of interpreting) my "unsteady.c" file, and i'm get the following error message:

(system "move user_nt.udf libudf\ntx86\2ddp")0 (system "copy C:\Fluent.Inc\fluent6.1.22\src\makefile_nt.udf libudf\ntx86\2ddp\makefile") 1 file(s) copied. 0 (chdir "libudf")() (chdir "ntx86\2ddp")() 'nmake' is not recognized as an internal or external command, operable program or batch file. 'nmake' is not recognized as an internal or external command, operable program or batch file.

Done.

Opening library "libudf"... Error: open_udf_library: The system cannot find the file specified.

Error Object: ()

Please help, it's urgent!!

Make sure path is set so nmake will be found. You may need to read up on setting environment variables.

Then make sure you can compile one of the standard udf examples.
