Hello everyone!
I am working to write a UDF that uses external functions to parse a .json file and read velocity data to impose at a domain boundary.
The UDF uses a DEFINE_PROFILE macro. All the headers needed (such as json.h) are included at the beginning of the file.
I launch fluent through Visual Studio as per regular UDF compilation.
However, I get this error:
udf.obj: error LNK 2019: unresolved external symbol

The error refers to the symbols I’m using to parse the .json file and its structure.
It is definitely a linker/compilation error but I can’t figure out how to fix it or if I am missing a compilation step.

Does anyone know how to solve this issue or have experience with a similar error?

Thank you in advance for any suggestion or help!
