I'm encountering few errors listed below. This happens when I try to run cpp code in matlab using mex command.
mesh.cpp(463) : error C2061: syntax error : identifier 'mxArray'
mesh.cpp(466) : error C2601: 'main' : local function definitions are illegal
mesh.cpp(464): this line contains a '{' which has not yet been matched
I'm doing it this way
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
int main(void)
{
<program content>
}
return;
}
Is this the right way of doing it?
Thanks in advance

Are you trying to use lcc to compile your .cpp ? lcc is strictly a C compiler that cannot be used for C++ at all. lcc also only supports the 1989 C standard and not any C introduced after that.
Also, you should not have a routine named "main": MATLAB itself is effectively the main routine. "main" is used strictly to designate the first routine called for an application, and is not used to designate routines called as library functions.
The structure should look similar to
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
<program content>
return;
}

Walter: Yes it worked. Actually I had a main cpp file and other mutilple cpp files linked to it. I didn't know that we should run all the files with 'mex'. I was trying only main cpp file.
Thanks again.

The problem with "const" went away when you removed the nested function?
