Hi,
I'm using an UDF in my analysis, the code works properly in a Windows system, the UDF is interpreted and I can use it inside my analysis.

/define/user-defined/interpreted-functions
"userdefined_6.c"
"cpp"
10000

no

However, when I try to do the same in a Linux environment, the UDF is not interpreted. I get this error:

Error: "userdefined_6.c": line 1: syntax error.
sh: /mypc/prod/applications/ansys/171/binary/v171/fluent/contrib/lnamd64/cpp: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

The line 1 contains:

#include "udf.h"

What could the problem be?
Thanks,
WhiteW

I have no experience with Linux
from google i found that most likely your problem is in compiler: conflict in x32 and x64 versions
try

yum install glibc.i686

or

yum install glibc.i386

I recommend you to compile your UDF not interpritate

best regards

Thanks AlexanderZ!

Hi, WhiteW!
Recently, I encountered the same problem with you about interpreting udf on linux system. The udf also runs well on windows using the command like you. Unfortunately, when i do the same in a Linux environment, the same error occurs:

sh: /opt/software/ansys_inc/v190/fluent/contrib/lnamd64/cpp: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
Error: "plate.c": line 1: syntax error.
sh: /opt/software/ansys_inc/v190/fluent/contrib/lnamd64/cpp: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

The first line of my udf code is " #include "udf.h"".

Could you please teach me how you handled the problem?
Thanks in advance.

Yours,
HC Yu
