Hi,

when I convert my .c file in a .mex file I have these errors:

Error treevalc.c: 92 illegal statement termination
Error treevalc.c: 92 skipping `int'
Error treevalc.c: 92 undeclared identifier `var'
Error treevalc.c: 92 type error: pointer expected
Error treevalc.c: 92 operands of = have illegal types `int' and `pointer to int'

The command line 92 is as follows:

int* var = (int*)mxGetPr(prhs[0]);

What should I change?


Thanks in advance

Andrea

Dear Andrea!

There is no error in this line. Please look in the line 91.

Kind regards, Jan

This is the code of my function, the errors that I have are in the last four rows

void mexFunction(int nlhs, mxArray *plhs[],
int nrhs, const mxArray *prhs[])
{
if (nrhs != 6) {
printf("Error: wrong number of input arguments: %d.\n", nlhs);
printf("Syntax: node_ids = treevalc(var, cut, left_child, right_child, catsplit, attributes)\n");
}
int* var = (int*)mxGetPr(prhs[0]);
double* cut = mxGetPr(prhs[1]);
int* left_child = (int*)mxGetPr(prhs[2]);
int* right_child = (int*)mxGetPr(prhs[3]);


Maybe the errors are caused by the fact that I use Windows and the code has been written for Linux?

I discovered that the problem is the IF but I do not know why

If this is C code, declaring new variables in the body of a code block is illegal. They must be declared at the top of the block only. C++ relaxes this rule. Your compiler may be using strict C rules.
