Interesting. I would like to investigate the problem. Is this an open
source project?

Unfortunately the project is proprietary in-house software.&nbsp; Using the
single header rather than passing all of the headers to module_builder
seems to solve the memory issue.&nbsp; It was the fact that classes are
included by default when you pass headers in individually, and not
included by default when included into a single header, that was
throwing me off.<br>
<br>
Now I just have to solve the multi-module dependency errors that have
started to show up, although I didn't get them when I was using the
method of passing all headers individually.&nbsp; I'll be sure to ask more
questions if I hit another roadblock.&nbsp; <br>
<br>
The Py++ project is quite nice, by the way.&nbsp; Thanks for providing it,
and offering help.<br>

    <pre wrap="">I read the section of documentation that said putting all of the headers
into a single header is the way to go. &nbsp;This is where I'm stuck, and I
don't have a lot of time to try and figure it out.

Here's a greatly simplified version of what I'm currently doing. &nbsp;Can
anyone tell me what I need to be doing instead?

Foo.h:
class Foo {
public:
&nbsp; &nbsp;Foo(void) { }
&nbsp; &nbsp;void test(void) { }
};

headers.h:
#include "Foo.h"

generate.py:
from pyplusplus import module_builder
GCCXML = '/path/to/gccxml'
mb = module_builder.module_builder_t(files=['headers.h'],
gccxml_path=GCCXML)
mb.build_code_creator(module_name='_test')
targets = mb.split_module('build')

When I run generate.py, it produces _test.main.cpp:
#include "boost/python.hpp"
#include "headers.h"
namespace bp = boost::python;
BOOST_PYTHON_MODULE(_test){
}

If instead of headers.h I pass Foo.h to module_builder_t, then it builds
fine, except this is the case where in my large project it consumes far
too much memory and takes too long. &nbsp;I tried having the pygccxml parser
generate an xml for headers.h and passing that to module_builder, but
that didn't work either. &nbsp;Looking at the xml file I do see the Foo
declarations though, so it's just module_builder that's ignoring them.

Any ideas would be greatly appreciated. &nbsp;I'm using the SVN version, on
Linux (if that matters).

The following documents should help you:
* <a class="moz-txt-link-freetext" href="http://language-binding.net/pyplusplus/documentation/tutorials/module_builder/module_builder.html">http://language-binding.net/pyplusplus/documentation/tutorials/module_builder/module_builder.html</a>
* <a class="moz-txt-link-freetext" href="http://language-binding.net/pygccxml/query_interface.html">http://language-binding.net/pygccxml/query_interface.html</a>

In general you can write:

mb.class_( 'Foo' ).include()
