D2 and gdb issue - gdb

Question

Short question: Is there any support of D2 in gdb (I have gdb 7.2) ?
Long story: I compiled next little application ...
// file main.d
int glVar = 0xAAAAAAAA;
void main()
{
glVar = 0xBBBBBBBB;
}
... using command "dmd -gc -debug main.d";
then I load it to gdb and trying to debug it:
vnm#vnm:~/proj/d_gdb_test$ gdb main

Why gdb can't show line information and why it shows symbols in mangled form ? Is this software issues or I'm doing something wrong ?

Answer 1

gdb has support for D starting with version 7.2. So, you can debug D programs with gdb 7.2.
Now, that doesn't mean that support is perfect - far from it in fact. For instance, I'm not sure that you can get it to print strings properly. And it's not at all surprising if it doesn't demangle D symbols. So, it works, but it's far from perfect.
