It's complex, ha? In the stateflow, I use a m file. And I want to generate the C code. So first I generate the m file to C code, which has been done successfully. But there are several C code files there. Then I want to use coder.ceval to call the C code but errors like this:
comtradeTest_sfun.c c:\code\project\scientific model\codegen\lib\fnmypronylast\rt_nonfinite.h(20) : error C2059: syntax error : '-' c:\code\project\scientific model\codegen\lib\fnmypronylast\rt_nonfinite.h(26) : error C2059: syntax error : 'type' c:\code\project\scientific model\codegen\lib\fnmypronylast\rt_nonfinite.h(28) : error C2059: syntax error : 'type' comtradeTest_sfun.c(13) : error C2143: syntax error : missing '{' before '.' comtradeTest_sfun.c(13) : error C2059: syntax error : '.' NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\Bin\amd64\cl.exe"' : return code '0x2' Stop.
Any ideas?

Hey,
To resolve the syntax errors when compiling the generated C code, follow these steps:
1. Inspect the Generated Code: Check the `rt_nonfinite.h` file at the specified lines for any syntax issues.
2. Ensure Compatibility: Verify that the generated code is compatible with your compiler.
3. Update Compiler: Consider using a more recent version of the compiler if you are using an outdated one.
4. Correct Errors: Address specific syntax errors related to misplaced characters or incorrect type declarations.
5. Simplify the Code: Break down the code into smaller parts to isolate and identify the problematic areas.
6. Use MATLAB Coder: Ensure that function signatures and data types match between MATLAB and the generated C code.
7. Consult Documentation and Support: Refer to MATLAB and Simulink documentation or contact MathWorks support for further assistance.
By following these steps, you can troubleshoot and resolve the compilation errors effectively.
