Hi all,
I'm an assembler/C programmer who has to convert my code over to run on C++, so with hope in my heart I changed my makefile gcc to g++. Surprisingly most seemed to compile OK, except for a series of errors all related to similar function calls, the errors are all like

common/ModelLoader.c: In function ‘void LoadLights(FILE*, MODEL*)’:
common/ModelLoader.c:116: error: invalid conversion from ‘void*’ to ‘light*’

and relate to mallocing structures inside structures

so the above error is produced from the line

model->number_of_lights=number_of_lights;
model->light = malloc (sizeof (LIGHT) * number_of_lights); THIS IS LINE 116

Can anyone advise what I need to do to make this run in C++ (g++)
I'm using etch and g++ 4.1.1 if that matters.

my C structure is
typedef struct model
{

int number_of_materials;
struct texture *material; /*list of materials used */

struct camera *camera; /*model cameras */
int number_of_lights;
struct light *light; /*light numbers positions etc*/
.....


which uses a structure

typedef struct light
{

float pos[3];
float lookat[3];
float ambient[4];
float diffuse[4];
float specular[4];

uint spotlight;

GLuint lightid;

}LIGHT;


I'm I allowed to use structures inside structures in C++.

Thanks in advance

The return value of malloc must be cast to the type in cpp. Consider using c++ code and not c in cpp ie typedefs where none are needed, struct keyword where not needed, new delete instead of malloc free, using constructors, destructors, member functions etc.
