Seems that "class" is ignored at "friend class a" within class definition
scope. This makes some code I have around not to compile. I may perhaps include
a file with all the classes available at the beginning... but it is ugly.
Nowadays I'm using gcc-3.4 instead of gcc-4.x
See below example of code that fails with gcc version >= 4.0
--8<---- demo.cpp, please do g++ -c demo.cpp -----8<--8<
class a;
//class c; // If uncommented, the code compiles. Otherwise it does not!
class b
{
friend class a;
friend class c;
a * aa;
c * cc;
private:
float p;
};
class a {
b bb;
void bp() { float f = bb.p; };
};
class c {
b bb;
void bp() { float f = bb.p; };
};
-->8---- demo.cpp, please do g++ -c demo.cpp ----->8-->8
