PythonMagick-0.9.1 fails to build (and patches to fix it)

[David Sveningsson]

Hi, I'm sorry if I'm not reporting this issue at the proper place, but I
wasn't able to find any where else.

When trying to build PythonMagick-0.9.1 it failed due to a number of issues.

using:
ImageMagick-6.6.2.5
gcc-4.4.4
glibc-2.11.2
boost-1.42.0

libtool: compile: x86_64-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I.
- -I../config -I/usr/include/python2.6 -I/usr/include
- -I/usr/include/ImageMagick -march=native -Os -pipe -msse3 -g -ggdb

- -MF .deps/libpymagick_la-_DrawableText.Tpo -c _DrawableText.cpp -fPIC
- -DPIC -o .libs/libpymagick_la-_DrawableText.o
In file included from /usr/include/ImageMagick/Magick++.h:11,
from _PathMovetoAbs.cpp:14:
/usr/include/ImageMagick/Magick++/Image.h:122: error: reference to

/usr/include/ImageMagick/Magick++/Image.h:122: error: expected ',' or

[snip]

The problem seems to be the usage of "using namespace boost::python;"
before including Magick++.h. If I swap the order of those that error
goes away but I get another error instead:

_Image.cpp:114: error: address of overloaded function with no contextual

[snip]

This seems to be caused by a API change from {un,}signed int's to
{,s}size_t, so updating these fixes the problem.

So here are two patches fixing the build problems and now it seems to work.

We will apply your patches and release PythonMagick-0.9.2 by sometime
tommorrow.

Thanks.
