I am trying to compile a simple "density variation with pressure" udf in Fluent 13 @ ubuntu 32bit
I get the following errors in the log file: (I have boldfaced the lines with error)

Hi Aditya,
I am facing the same problem which you posted in 2013. Please let me know how you could solve it. I am getting the following error:
/usr/include/time.h:226:5: error: unknown type name ‘__locale_t’

Eagerly awaiting your reply.
regards,

Hi,
I do not exactly remember how I had solved this issue. But I do remember that this PDF helped me a lot. I have attached it to this post. See if it helps you.

could I get some help with this?

The following procedure is for 64 bit Window OS. First, install Visual C++ 6, check the environment variable at the end of the installation. Then, install visual studio 2010. Finally compile you UDF. For 32 bit OS simply just use Visual C++ 6.
However, for 32 bit Linux OS you need to install C++ compiler, I am not sure that gcc/g++ will work in this case, but I am sure that you need to have C++ compiler which links correctly with your fluent for using its external compiler.
Besides, please note to your UDF capability in case you are running in parallel.
