Default open_udf_library: The system cannot find the file

I am trying to compile a UDF. I put the .c file and udf.h file in the same directory as the .cas file. there is no other .h file created by myself. When I clikc "build", it did create the directory and copy a few files in that directory, but when click "load" it gave me an error message say "Error: open_udf_library: The system cannot find the file specified."

Did you solve this issue? I have the same problem with my UDF files. Thanks.

This is very common issue and it caused if due to any reason the library is not compiled. Compilation generates a library with extension .so (.dll in case of Windows). If compilation fails then this file is not generated. The existence of other files are not useful in the end. Check for errors during compilation.

Hey Vinerm,

Thanks for your reply. I used Fluent 6.3.26 32 bit version and visual studio 2012 ultimate. My operation system is 64 bit. I tried to use the visual studio command prompt to compile the UDF file. When I clicked the load buttom, it gives me errors Opening library "libudf"...
Error: open_udf_library: The system cannot find the file specified.


So I am not sure if visual studio 2012 ultimate is compatible with my fluent or not. Because when I opened the visual studio command prompt, the name of it is "VS2012 X64 Cross Tools Command Prompt". In such way, this version of visual studio is 64 bit. However, I searched online and found that Microsoft didn't release 64 bit VS2012 (https://stackoverflow.com/questions/...io-2012-64-bit).

Any suggestions of how to solve this problem?

Thanks a lot,
mcc007

During compilation, it generates a log in the same directory where you have case files. Could you copy that log in the post?

Hey Vinerm,

Thank your reply. I solved this problem by reinstalling the VS.
