typedef struct _cuobject cuObject;
//pointers to function
typedef int (*comparefunc)(const cuObject*, const cuObject*, int);
typedef struct _cutype{
comparefunc compare;
} cuType;
__host__ __device__ int object_compare(const cuObject* a, const
cuObject* b, int op){
return -1;
}
typedef struct _cuobject{
static cuType* type;
__host__ __device__ _cuobject(){
//type = NULL;
if(type == NULL){
cuType cuobjecttype = {
object_compare,

type = &cuobjecttype;
}
}
} cuObject;
int main(){
cuObject c;
}
I didn't put all the code but only the main part.
The error correspond to the line "if(type==NULL)":
test.cu(79): error: identifier "_ZN9_cuobject4typeE" is undefined
Seems that the compiler doesn't see the static pointer.
