Hello,
I am trying to compile an UDF but it shows some error. How can I fix it. Here is the attachment.

Plz have a look...

You can fix it by changing your udf.

We can not tell you what is wrong in your udf, because you did not include your udf. Including the error message was a good start, because it shows that something is wrong on line 12 and possible line 45, but we can not see what is on line 12, so we can not give any advice on how to correct it.

Here is the UDF
/************************************************** ************************************/
/* UDF for computing cell co-ordinates */
/************************************************** ************************************/

#include "udf.h"
#include "sg.h"
#include "prop.h"
#include "dpm.h"
#include "surf.h"
#define WALL_ID 8

User_Particle_Vars *user_particle_vars;


DEFINE_DPM_SCALAR_UPDATE(particle_coords, c, ct, initialize, p)
{
real A[ND_ND];
int n;
face_t f;
Thread *ft;
c_face_loop(c, ct, n)
{
f=C_FACE(c, ct,n);
ft=C_FACE_THREAD(c, ct, n);
if (NNULLP(ft))
{
if (THREAD_ID(ft)== WALL_ID)
{
p->user[0] = p->state.pos[0];
p->user[1] = p->state.pos[1];
p->user[2] = p->state.pos[2];

}
}

}
}

DEFINE_DPM_OUTPUT(Particle_coords_output, header, fp, p, thread, plane)
{
char name[100];
if (header)
{
if (NNULLP(thread))
cxprintf(fp,"(%s %d)\n",thread->head->dpm_summary.sort_file_name,8);
else
cxprintf(fp,"(%s %d)\n",plane->sort_file_name,8);

cxprintf(fp,"\n %10s %10s %10s",
"X", "Y", "Z");
}
else
{
sprintf(name,"%s:%d",p->injection->name,p->part_id);
cxprintf(fp,
"%10.6g %10.6g %10.6g\n", p->user[0], p->user[1], p->user[2]);
}
}

Line 12 is

User_Particle_Vars *user_particle_vars;

I don't know why you add this. You never use this pointer. It looks to me like you can simply delete this line...

Line 45 is

cxprintf(fp,"(%s %d)\n",thread->head->dpm_summary.sort_file_name,8);

The problem is in "thread->head->dpm_summary". How did you come to this? The structure is apparently not correct, but I don't know how you came to this structure, so I don't know what you want this part of the code to do.

Ok, I got the point and trying to fix it........

Thank you.
