--------------------------



Updated: 2010-12-12



Work in progress.

1) Working

   Build 32 bit and 64bit builds of exiv2.exe (and libraries exiv2lib,expat,zlib,xmpsdk) in 32bit and 64bits.

   Builds with VS2005, 2008 and 2010.



2) TODO (in priority order)

   a) Provide support for zlib1.2.5

   b) Use .vsprop files to hold "common" project settings

   c) Build sample/test applications (exifprint etc)

1    Build Instructions

1.1  Install zlib and expat sources.

     I use the directory c:\gnu for this purpose, however the name isn't important.



     c:\gnu>dir

      Directory of c:\gnu

     2010-12-05  10:05    <DIR>             exiv2                <--- this tree

     2010-12-02  21:06    <DIR>             expat-2.0.1          <--- "vanilla" expat 2.0.1 source tree

     2010-12-02  20:58    <DIR>             zlib-1.2.3           <--- "vanilla" zlib 1.2.3 source tree

     c:\gnu>



1.2  Open exiv2\msvc64\exiv2.sln

     batch build, select all, build

     - you will build 5 projects x 2 Platforms (x64|Win32) x 4 Configurations (Debug|Release|DebugDLL|ReleaseDLL)

     = 5x2*4 = 40 builds.

     

     If you don't have the x64 compiler available, don't select the 64 bit configurations!

     

1.3  What is built

     The DLL builds use the DLL version of the C runtime libraries

     The Debug|Release builds use static C runtime libraries

     This is discussed in exiv2\msvc\README-MSVC.txt 



2    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.





zlib and expat

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

..\..\..\zlib-1.2.3\                   Source code



msvc64\expat\expat.sln expat.vcproj DevStudio Solution and Project files

..\..\..\expat-2.0.1\                  Source code



2.1  Architecture

     There are directories for every component:

     The libraries: zlib, expat, xmpsdk, exiv2lib

     Applications:  exiv2 (exifprint and other sample apps can be added on request)

     

     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

     

2.2  Changing the version of expat/zlib/xmpsdk

     The directory expat is a copy of expat, zlib is a copy of zlib

     

     As new versions of the libraries become available (eg zlib125) it will be added.

     Build instructions for zlib1.2.5 will be provided once zlib1.2.5 has been integrated.



2.3  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.

3.1  Differences between inherited project and the exiv2 projects

     There is no compatiblity.
