Hello,
I'm trying to use `gdb` to debug D binaries, but I'm having
trouble accessing the methods of a struct or class. It seems that
`gdb` doesn't see them.
Given the following simple example
```
// test.d
struct S
{
int x;
void myPrint() { writefln("x is %s\n", x); }
}
void main(string[] args)
{
S s;
}
```
Compile the source file with debug simbols (`dmd -g test.d
-of=test`) and open the binary with gdb (`gdb test`) and run the
following
```
break _Dmain # break at D entry point
run
ptype s
type = struct test.S {
int x;
}
print s.myPrint()
Structure has no component named myPrint.
```
As you can see, when I try to access the `myPrint()` method I get
the error
"Structure has no component named myPrint."
Looking up gdb's bugzilla, I've found this issue [0] that
basically says that gdb treats D as C code (and that would
explain why it doesn't look for function definitions inside D
structs).
A simple "fix"/"hack" to this problem is to define a helper
function that will take my symbol as a parameter and internally
call the function that I need, like below:
```
extern (C) void helper(ref S s) { s.myPrint(); }
```
While this does the job for this trivial example, it doesn't
scale for a real project.
Are there any solutions to this problem?
Looking forward to your answers,
Edi
