[pygccxml-development] Boolean operator == with std::vector

[Romain C. <rom...@gm...>]

Hi,

I am using Py++ to generate the bindings for a C++ class using a vector of
objects (i.e std::vector<MyObject>)

I got this error:

"the next line of code will not compile, because "::MyObject" does not have
operator== !"

Could anyone tell me why I need to define this boolean operator?

Cheers,

Romain

Do you use indexing suite, that comes with boost? If so, you need this
operator for "contains", "index" and other functionality.
You can switch to indexing suite v2 and than you will not have to
define the operator.

Oh ok. Thank you for this hint.

However, I changed to indexing suite version 2 and I got the following lines
at the beginning of the generated files:

// This file has been generated by Py++.

#include "boost/python.hpp"

#include "boost/python/suite/indexing/value_traits.hpp"

#include "boost/python/suite/indexing/container_suite.hpp"

#include "boost/python/suite/indexing/vector.hpp"

"value_traits.hpp" is not part of the Boost Python library and should be
provided by Py++ (cf.
http://www.language-binding.net/pyplusplus/documentation/containers.html#indexing-suite-version-2-installation
).

Did I miss something??

I don't understand you. Anyway I suggest you to try to use SVN
version, as it doesn't require boost directory modification.

HTH

I was using the version 1.0.0 from SourceForge. Why the version 1.1 is not
on SourceForge? (cf. http://sourceforge.net/projects/pygccxml/files/)

I will get the SVN version and try again.

Thank you!
