I have encountered some problems in learning acusolve acu-4002, and I have been unable to run gravity.c file. My compiler software has been installed (VS2013), and the environment configuration has been completed according to the relevant information (Figure 1). However, the following problem was encountered in operation (Figure 2). The gravity. obj file cannot be found, nor can the. Dll file be generated.


I also tried to run gravity. C program separately in VS2013, but I also found many errors. (Fig. 3)

1. error LNK2019: Unparsable external symbol _udfCheckNumUsrVals, which is referenced in function _usrGravity

2. error LNK1120: Three unresolved external commands

3. IntelliSense: Undefined identifier "Integer"

4. IntelliSense: Undefined identifier "String"

5. IntelliSense: Undefined identifier "Void"

6. IntelliSense: Undefined identifier "Real"

I hope you can help me. Thank you very much.

Hello, do you know how to call UDF library? Error LNK 2019: An unrecognizable external symbol XX, which is referenced in function XX, has been appearing all the time. It seems to be due to the lack of Library files.

If you're issuing the acuMakeDll command from the AcuSolve Command Prompt, the libraries should all be readily available.  Please describe the process you used, and share any images of the window showing the errors and your process.
