[pygccxml-commit] string type mismatch between python and C++

[Johnson L. <joh...@op...>]

Hi:

 

I am extending an embedded python using PY++ (a great product, along
with Boost, IMHO), my problem is that the C++ function being called from
Python takes a (wstring) or wchar argument, but the corresponding
function signature assigned to Python seems to take a regular str.  So
when I try to make a call I get...

 

    ClassificationOutput.setApplicationName(ClassificationOutput, str)

did not match C++ signature:

    setApplicationName(struct ClassificationOutput_wrapper {lvalue},
class std::basic_string<unsigne

d short,struct std::char_traits<unsigned short>,class
std::allocator<unsigned short> > applicationNa

me)

    setApplicationName(class ClassificationOutput {lvalue}, class
std::basic_string<unsigned short,s

truct std::char_traits<unsigned short>,class std::allocator<unsigned
short> > applicationName)

 

And obviously that doesn't work.  The funny thing is while python can't
pass a string into C++, C++ can pass that wchar to Python just fine.
This simple string exchange seems such common place that it must have
been solved multiple times before, but I just can't get a handle on how
to deal with it.

 

Any help is greatly appreciated.
