Summary: "friend class" implies forward declaration "class"?
Product: clang
Version: trunk
Platform: Macintosh
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
The following example will compile in g++ but not in clang++:
#include <stdio.h>
/* If you uncomment the forward declaration, then this compiles OK
(but g++ does not require the forward declaration):
*/
// class FooImpl;
class Foo_connection {
private:
friend class FooImpl;
Foo_connection(FooImpl&);
};
int main() {
int i = 1;
printf("%d \n",++i);
}
