hi everybody,

I have some problem with compiling my udf. I didn't work before with udfs. I searched the forum for my problem but I cannot solve it.

when I want to build my udf the this error apears:

Deleted old libudf\ntx86\2d\libudf.dll
        1 file(s) copied.
        1 file(s) copied.
(system "copy C:\Fluent.Inc\fluent6.3.26\src\makefile_nt.udf libudf\ntx86\2d\makefile")
        1 file(s) copied.
(chdir "libudf")()
(chdir "ntx86\2d")()
'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,

Done.

I think this error originates from Env. variables.
Is anybody here that can help me?!?!?!? what should I do???
