Hi! :)
I'm on the best way to become completely insane.
I'm trying to set up VS2005 to run Boost Python in debug mode.
Sorry for the long text...
Problem summary:
- applications crash in debug mode
- dependencies to python25_d.dll AND python25.dll in
boost_python-vc80-mt-gdy-1_35.dll - normal??
Only today I found out that I have to pass a special parameter to REALLY get
a debug version.
So I went into .\boost_1_35_0\libs\python\example\quickstart
and called bjam with:
bjam toolset=msvc --verbose-test test python-debugging=on
Finally I got my boost_python-vc80-mt-gdy-1_35.dll & .lib files.
Yet, simply defining BOOST_DEBUG_PYTHON & BOOST_ALL_NO_LIB in the header
didn't work out.
Had to put them in the preprocessor to make VC8 use the ...-gdy-... lib
instead of the ...-gd-... lib.
And to make him stop importing Python25.lib instead of python25_d.lib when
building my .pyd C extension.
Finally I found out that I have to add a _d to my extension filename as well
so that python_d.exe finds the class I want to import.
But now... my application crashes right after starting.
Even the HelloWorld application from the tutorial crashes instantly:
Unhandled exception at ... in python_d.exe
And the debugger points to boost_1_35_0\libs\python\src\object\class.cpp's:
[...]
BOOST_PYTHON_DECL type_handle class_type()
{
if (class_type_object.tp_dict == 0)
{
class_type_object.ob_type = incref(class_metatype().get());
class_type_object.tp_base = &PyBaseObject_Type;
=>!!! if (PyType_Ready(&class_type_object))
return type_handle();
// class_type_object.tp_setattro = class_setattro;
}
return type_handle(borrowed(&class_type_object));
}
[...]
Additionally, when putting boost_python-vc80-mt-gdy-1_35.dll in dependency
walker I find dependencies to python25_d.dll AND python25.dll in it.
I temporarily deleted python25.lib for testing ... and indeed, bjam demands
python25.lib when building.

I hope someone with more experience got a clue...
I'm lost. :(
Thanks,
Martin
