Exiv2

Hi Olivier,

I use the attached script to cross-compile the exiv2 windows executable that is available on exiv2.org on my Debian system.
The libraries and header files that I use here are also attached, although I recommend you build or otherwise get your own - I don't remember where I have these from.

Thanks a lot Andreas, I'll experiment with your script and write about my findings (I'll probably document the full build process for pyexiv2 on windows anyway).

I finally found the time to experiment with cross-compilation, and with the help of your script I found it pretty straightforward to cross-compile libexiv2 statically, which is what I want for pyexiv2.
Getting the other dependencies to compile (in particular boost_python) was much more of a hairy problem, but that's off topic here.

I wrote a very basic shell script that retrieves the dependencies and compiles them, here is how it looks, up to compilation of libexiv2:

#!/bin/sh

BASE=$HOME/dev/win32
mkdir -p $BASE
cd $BASE

PLATFORM=i586-mingw32msvc
COMPILER=$PLATFORM-g++
ARCHIVER=$PLATFORM-ar

# zlib (for exiv2)
wget http://gnuwin32.sourceforge.net/downlinks/zlib-lib-zip.php
unzip -d zlib zlib-*.zip

# iconv (for exiv2)
wget ftp://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
tar xzf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1
./configure --enable-static --disable-visibility --target=$PLATFORM --host=$PLATFORM --build=i586-linux --prefix=$BASE/libiconv
make
make install
cd ..

# expat (for exiv2)
wget http://sourceforge.net/projects/expat/files/expat/2.0.1/expat-2.0.1.tar.gz/download
tar xf expat-2.0.1.tar.gz
cd expat-2.0.1
./configure --disable-shared --disable-visibility --target=$PLATFORM --host=$PLATFORM --build=i586-linux --prefix=$BASE/expat
make
make install
cd ..

# exiv2
wget http://exiv2.org/exiv2-0.19.tar.gz
tar xzf exiv2-0.19.tar.gz
cd exiv2-0.19
./configure --disable-shared --disable-visibility --target=$PLATFORM --host=$PLATFORM --build=i586-linux --disable-nls --with-zlib=$BASE/zlib --with-libiconv-prefix=$BASE/libiconv --with-expat=$BASE/expat --prefix=$BASE/exiv2
make
make install
cd ..

And voilà, the result is located in $HOME/dev/win32/exiv2/.

Have you an updated version of your script that reflects new versions of all that libs?
I would like to compile my patched version of exiv2 for win32 (maybe 64) using linux.
Or is there a new way for cross-compiling?

The latest version of the script above can be found in pyexiv2's trunk branch: http://bazaar.launchpad.net/~osomon/pyexiv2/pyexiv2-0.3/view/head:/cross-compile.sh

It currently only works for win32 (64 bits support is not there yet). I hope this helps.
