Just a note, since you seem to be implying that GDB *only* works with
G++.

It also works with HP aCC, as HP took the time to implement the
necessary code.
And as part of making the GCC V3 C++ ABI work properly, i'll be
abstracting this stuff a lot better.

Re: GDB on AIX 4.3.3 and C++ with native xlC

Sorry, but GDB does not support debugging xlC code.
This would be a non-trivial task and no one has volunteered yet.

 Hi !
 
 I am running GDB 5.0 on a IBM AIX 4.3.3 and have C++ code compiled with
 the native VisualAge 5.0 development environment using the xlC compiler
 to compile C++ code.
 
 I run into problems displaying member variables etc in C++ classes, it
 seems somewhat disoriented by the  'this'-pointer. 
 
 A small sample:
 class CMyClass {
 public:
 CMyClass() {
   m_Mem1 = 0;
 }
 ~CMyClass() { m_Mem1 = -1; }
 
 void Func1()
   {
   int some_var = 1;
   }
 
 void Func2(int in) {
   m_Mem1 = in;
 } 
 public:
 int m_Mem1;
 };
 
 
 int main (int argc, char **argv)
 {
 CMyClass myclass;
 
 myclass.Func2(2);
   
 return 0;
 } 
 
 
 The GDB output:
 
 0x10001170 in main (argc=1, argv=0x2ff21e10) at main.C:31
 (gdb) n
 (gdb) s
 CMyClass::Func2 (this=0x2ff20cec, in=2) at main.C:20
 (gdb) p this
 $1 = (struct unknown *) 0x2ff20cec
 (gdb) p in
 $2 = 2
 (gdb) p m_mem1
 Internal error: `this' is not an aggregate
 (gdb) p *this
 $3 = incomplete type
 (gdb) 
 
 
 Does'nt the GDB work with native AIX compiler ?
 Debugging C-code works all OK.
 
 Any hints ?
