Matlab coder there is no enumerated value named 'rtw:lib' problem under debian

Hello,

I am having difficulties with the matlab coder when I try to convert a simple matlab function to c++ code. My function is

function [ret]=add(val1,val2)

ret=val1+val2;

end

When I try to build it as a C++ executable or static library with coder I get the the following error

there is no enumerated value named 'rtw:lib'

My compiling configuration is for X86. But there is not any problem when I build it as a mex function and get the function's corresponding c code with header and the code file.

What may cause the problem for C++ building?

Thank you.

What is the exact command you use when the error occurs?
