Dumpers not working on OSX. :(

[hackdev]

Hi,

I was trying to get the Dumpers to work on OSX Yosemite based on the information found here: http://doc.qt.io/qtcreator/creator-debugging-helpers.html
However for some reason they aren't working, and there seems to be no error.

Here's my test code:
#include <iostream>
using namespace std;

struct vec3 {
vec3(const float& x = 0.0f,
const float& y = 0.0f,
const float& z = 0.0f)
: x(x)
, y(y)
, z(z)
{}

float x, y, z;

};

int main(int, char**) {
vec3 v;
cout << v.x << ' ' << v.y << ' ' << v.z << endl;
return 0;
}

---

And here's my dumpers:
#!/usr/bin/python

def qdump__vec3(d, value):
x = value["x"]
y = value["y"]
z = value["z"]
d.putValue('(%.3f, %.3f, %.3f)' % (x, y, z))
d.putType("vec3")
d.putAddress(value.address)
d.putNumChild(0)

---

I tried to load the dumpers by putting
python execfile('/path/to/file/DebugHelpers.py')
in both ~/.gdbinit and "Additional Startup Commands".
In both cases the debugger log prints:
GdbStartupCommands: python execfile('/path/to/file/DebugHelpers.py') (default: ) ***
But the type is not printed according to the qdump__vec3.

Am I doing something wrong here?
Thank you for your time.

System: I installed Qt5.4.1 and which comes with QtCreator 3.4. Also installed X-Code 6.3.1.
