Question

I have a struct like this in “parser.h”

struct obj{
        char *filename;
        unsigned long nverts;
        unsigned long curvert;
        double (*verts)[3]; 
        unsigned int *faces[3]; 
};

typedef obj obj;

and in parser.cpp

I am declaring

  obj objmesh;

    objmesh.filename="c://temp//wings.obj";
    objmesh.nverts = 20;
    objmesh.verts = (double (*)[3]) malloc( objmesh.nverts *  sizeof(double[3]) );
    objmesh.curvert = 0;

When I do these assigments at the top of the parser.cpp I get “‘objmesh’ does not name a type” error.

But when I put all these assignments in a function in parser.cpp (while obj objmesh; has global scope) , I get no error and compiles fine.

Can anyone think of a reason why that is the case? I am using Mingw Gnu 4.6 C++ compiler

You need your assignments inside a function, e.g:

obj objmesh;

... 

int main(int argc, char **argv)
{
... possibly other stuff here... 
    objmesh.filename="c://temp//wings.obj";
    objmesh.nverts = 20;
    objmesh.verts = (double (*)[3]) malloc( objmesh.nverts *  sizeof(double[3]) );
    objmesh.curvert = 0;
... More code here ... 
}

By the way:
double (*)[3]) begs for a typedef…
