Default Errors when Compiling UDF: error C2040/error C2099

Hallo,

I would like to use a very simple UDF, which writes informations of particles into a file. For compiling the UDF, I downloaded 'Visual C++ 2008 Express', go to the 'libudf\ntx86\3d>' directory and type 'nmake'.

Here is my UDF-Code:

------------------------------------------------------------

/*#define USE_FLUENT_IO_API 1*/

#define USE_FLUENT_IO_API 0

#include "udf.h"

FILE *fp;

fp = fopen ("myfile.txt","w");

DEFINE_DPM_OUTPUT(discrete_phase_sample,header,fp, p,t,plane)

{

float x,y,z;

x = P_POS(p)[0];

y = P_POS(p)[1];

z = P_POS(p)[2];

fprintf(fp,"%d %f %f %f\n",p->part_id, x, y, z);

}

------------------------------------------------------------

Quite simple I guess, but anyhow, my computer doesn't like the 'FILE' command. Here is what I get, after I typed 'nmake':

------------------------------------------------------------

Setting environment for using Microsoft Visual Studio 2008 x86 tools.

c:\Users\Casper\Desktop\UDF-test\libudf\ntx86\3d>nmake

c:\Users\Casper\Desktop\UDF-test\libudf\ntx86\3d>

------------------------------------------------------------

Here are some information about my system:

Windows Vista 32-bit

dual-core 1.6GH 64-bit

Fluent 6.3

Visual C++ 2008 Express Edition

I searched the Forum and the internet for some solution but couldn't find any.

Hope, you can help me,

best wishes,

Julian

Hai

try to start fluent from Vc++ command prompt and then compile udf.. Hopefully it will work. almost all the 'nmake' error occurs because of this.

regards sk.
