I'm trying to compile the example from the Boost Python docs without
success.
hello.cpp:
#include
char const * const greet() {
return "hello, world";
}
BOOST_PYTHON_MODULE(hello_ext) {
using namespace boost::python;
def("greet", greet);
}
I have Boost 1.48, Python 2.7, a
Hi,
I'm new to python.boost library and I'm trying to use it to wrap a third
party library. Everything else I've managed to get working - thanks to
excellent library and lot of examples I've found around a net.
Only thing I can't get working properly is instance ownership transfer

When returning a pointer, you have to tell Boost::Python what to do with
it. The most important issue is one of ownership. Once the pointer has been
returned as a Python object in
It looks like you inserted an extra const (I don't see it in the current
tutorial) ...
char const * const greet() {
It should work if you remove it.

Oops, I meant to mark the extra const with a color:

Ha! You're correct. The example program was so short that I just retyped
it, and I made the pointe

I want to do it another way around:
Instance of Owner should hold reference to data_1 and data_2 as long as
owner is alive.
Now following happens:
owner = Owner()
data_1 = Data(owner) # data_1 ownership is transferred to owner object
data_2 = Data(owner) # data_2 ownership is transferred to owner
Jani,
ok what you want to do is quite a lot more intrusive, so you need some
more involved methods, but it should be possible. I would do it by
noting the following
- data_1 is published to python as a boost::shared_ptr (default
holder type)
- usually it is difficult for a class member function,
Hi,
I'm still strugling with this whole thingy so I came up with more
concrete example I'm trying to achieve:
http://pastebin.com/dVRfT56x
And in python code I do like this:
owner = Owner()
data = Data(owner)
After script is finished I get warning message that Data destructor
shouldn't be
