Updated: 2010-12-07
This is "work in progress". At this time, you can build the libraries and the exiv2.exe application.
You cannot build the test applications such as exifprint.exe

1 Design
expat and zlib do not provide 64bit builds for DevStudio, so it has been necessary to create the build environments for exiv2. However, we don't include the source code for zlib or expat - only the build environment. You are expected to install the "vanilla" expat and zlib libraries in a directory at the same level as exiv2. I personally always build in the directory c:\gnu - however the name/location/spaces of the build directory are all irrelevant, it's only the relative position of expat-2.0.1 and zlib-1.2.3 which matter. The names expat-2.0.1 and zlib-1.2.3 are fixed.

msvc64\zlib123\zlib.{sln|vcproj} DevStudio Solution and Project files

msvc64\expat201\expat.sln expat.vcproj DevStudio Solution and Project files
..\..\..\expat-2.0.1\ Source code
1.1 Architecture
There are directories for every component:
The libraries: zlib123, expat201, xmpsdk, exiv2lib
Applications: exiv2, exifprint etc......
For each component, there are three build directories:
exiv2lib\build intermediate results
exiv2lib\Win32\{Debug|Release|DebugDLL|ReleaseDLL} 32 bit builds
exiv2lib\x64\{Debug|Release|DebugDLL|ReleaseDLL} 64 bit builds
1.2 Changing the version of expat/zlib/xmpsdk
The directory expat is a copy of expat201, zlib is a copy of zlib123
As new versions of the libraries become available (eg zlib125) it will be added.
To build exiv2 with zlib125, the directory zlib125 should be copied to zlib.
1.3 Relationship with msvc build environment
This environment is similar to msvc (same build engineer). However there are significant differences:
1) Support 64bit and 32bit builds
2) Provides projects to build expat and zlib
3) Is designed to accomodate new versios of expat and zlib when they become available.
4) Does not require you to build 'vanilla' expat and zlib projects in advance
5) Does not support the organize application
6) Supports DevStudio 2008 and 2010 (no support for 2003 and 2005)
msvc will continue to be supported for 32 bit builds using DevStudio 2003 and 2005,
however there is no plan to enhance or develop that environment going forward.

I recognise and respect the work performed by those individuals.
2.1 Differences between inherited project and the exiv2 projects
There is no compatiblity.
3 Build Instructions
1) Install zlib and expat sources
2) Open exiv2.sln, batch build, select all, build
If you don't have the x64 compiler available, don't select the 64 bit configurations!
# That's all Folks!
