Fix: Having GCC generate the correct debugging info would be a good first step. From: David Carlton <carlton@kealia.com> To: gdb-gnats@sources.redhat.com Cc: Subject: Re: gdb/830: GDB doesn't know about namespace aliases Date: Wed, 17 Mar 2004 12:16:06 -0800 On 15 Nov 2002 21:51:26 -0000, carlton@math.Stanford.EDU said: > Having GCC generate the correct debugging info would be > a good first step. I believe GCC does now generate the appropriate debugging info. (I think GCC 3.4, maybe GCC 3.5 instead.)

Here's another testcase.
namespace foo
{
int x = 42;
void baz () {}
}
namespace bar = foo;
int
main ()
{
bar::baz ();
return 0;
}
printing bar::x works, but setting a breakpoint on bar::baz() doesn't work.

[Converted from Gnats 830] GDB doesn't know about namespace aliases in C++. Release: GNU gdb 2002-11-15-cvs Environment: any How-To-Repeat: Compile this file: namespace A { int x = 1; } namespace B = A; int main() { B::x; return 0; } Then run GDB on it and try to print out B::x.
