Compiling UDF
 

Hello everyone!

After I input the command :make "FLUENT_ARCH=irix6r10"

The following information appear:

.... sh: cc: not found error code 127 (bu21) "libudf.so" not remade because of errors (bu14) ....

Anyone know how to solved it?

I am pretty sure that my UDF code was right because it can run smoothly in "interpreted" mode.

Have a nice day!

Re: Compiling UDF
 

That error means your unix machine doesn't have a C compiler. Get the compiler that is fit to your unix machine.

Thanks! But some other problems come out.

This is the UDF I use: DEFINE_SOURCE(Esource_ball, cell, thread, dS, eqn)

When compiling, it give the message like this:

The parametr "ds" was never referenced. The parametr "eqn" was never referenced.

What is the possible reason for this message?

you can detail explain your problem in here , i operated software of FLUENT for a lot times so , i hope to assist you to solve problem ...

Thanks!

When comiling the following code, some error messages will give like this:

cc-3201 cc: REMARK file= source.c, line=9 The parameter "eqn" was never referenced

By the way, how to build a ellipse volume in Gambit 1.3.

Have a nice day!

Re: Compiling UDF
 

please added this item (eqn) inside your program . error message told you that your program must exist the argument of "eqn" , because you defined the argument[DEFINE_SOURCE(Gsource_ball, cell, thread, dS, eqn)] previously .but , you didn't write this argument(eqn)in above model. so , you can modify this code of program ,

For example: **************** source=13*P+201; /*P is variable */ ds[eqn]=201; ****************
