1    Build Instructions



1.1  Tools

     This has been tested with the "Pro" versions of VS 2005/08/10/12

     Some Express editions don't support 64 bit builds

     however it is  possible to build 32 bit libraries with "Express".

     See notes below about DevStudio Express and building only Win32 or x64 builds

     

     You need a DOS version of perl to build openssl.  Not the cygwin version.  I use ActiveState Perl.

     

     You need Cygwin to run the test suite because it is written in bash.



1.2  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

     2012-05-04  23:35     <DIR>    expat         <--- "vanilla" expat   2.1.0  source tree

     2012-05-04  23:35     <DIR>    zlib          <--- "vanilla" zlib    1.2.7  source tree

     2012-05-04  23:35     <DIR>    curl          <--- "vanilla" curl    7.39.0 source tree

     2012-05-04  23:35     <DIR>    openssl       <--- "vanilla" openssl 1.0.1j source tree

     2012-05-04  23:35     <DIR>    libssh        <--- "vanilla" libssh  0.5.5  source tree

     c:\gnu>

     

     You can obtain the libraries from http://clanmills.com/files/exiv2libs.zip (20mb)

     I copy those to the directory c:\exiv2libs

     The script msvc2005/copylibs.bat will copy them from c:\exiv2libs to the correct location

     

     11/05/2014  07:26 AM  <DIR>  curl-7.39.0

     12/07/2014  09:18 AM  <DIR>  expat-2.1.0

     12/17/2014  09:40 AM  <DIR>  libssh-0.5.5

     12/17/2014  09:38 AM  <DIR>  openssl-1.0.1j

     12/07/2014  09:18 AM  <DIR>  zlib-1.2.7

     

     The following directories are also in the archive for use by msvc2003

     01/07/2015  11:11 AM    <DIR>          expat-2.0.1

     01/07/2015  11:10 AM    <DIR>          zlib-1.2.3



     The URLs from which to obtain zlib and expat are documented in exiv2\msvc2003\ReadMe.txt

     expat-2.1.0 is available from http://voxel.dl.sourceforge.net/sourceforge/expat/expat-2.1.0.tar.gz

     zlib-1.2.7  is available from http://zlib.net/zlib-1.2.7.tar.gz

     curl        is available from http://curl.haxx.se/download.html

     openssh     is available from https://www.openssl.org/source/

     libssh      is available from https://www.libssh.org/get-it/



1.3  Open exiv2\msvc2005\exiv2.sln

     Projects are zlib, expat, xmpsdk, exiv2lib, exiv2, addmoddel etc...

     Build/Batch build...  Select All, Build

     - 36 projects      (zlib, expat, xmpsdk, exiv2lib, exiv2, addmoddel etc)

     x 2 Platforms      (x64|Win32)

     x 4 Configurations (Debug|Release|DebugDLL|ReleaseDLL)

     = 36x2x4 = 288 builds.

     

     When building with webready, you add 5 libraries for a total of 328 builds.



     If you haven't installed the x64 compiler, don't select the 64 bit configurations!

     You may have to hand-edit the vcproj and sln files to hide the 64 bit information.

     See the notes about DevStudio Express for more information about this.



     Build time is 20 minutes on a 2.2GHz Duo Core and consumes 3.0 gBytes of disk space.

     Build time with webready is of the order of one hour as we add 5 libraries.

     (libcurl, libeay32, ssleay32,libssh,openssl)



1.4  Building with and without webready

     Building the complete library with webready support requires building

     5 additional libraries.  This is time consuming.  The build time

     increases from 5 to 20 minutes.

     

     By default, you will not build with webready.

     

     To build with webready:

     1 copy include\exiv2\exv_msvc-webready.h include\exiv2\exv_msvc.h

     2 open msvc2005\exiv2-webready.vcproj      



1.5  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\msvc2003\ReadMe.txt 



1.6  Express editions of DevStudio (or 32 bit only builds, or 64 bit only builds)

     Some Express Editions do not provide a 64 bit compiler.

     You can build 32 bit libraries with DevStudio Express (with a little effort)



     Before loading the project, use the python script setbuild.py to select Win32:



        c:\gnu\exiv2\msvc2005>setbuild.py Win32



     setbuild.py is none destructive.  If you have a 64 bit compiler, you can:

     1) Restore the build environment with:   setbuild.py all

     2) Select x64 bit builds only with:      setbuild.py x64



     If you don't have python available (it's a free download from ActiveState.com), 

     you can "doctor" to project files manually to remove mentiosn of X64 using an editor:



     Cleanup your tree and edit the files.

     cd exiv2\msvc2005

     call cleaner.bat

     for /r %f in (*.vcproj) do notepad %f

     for /r %f in (*.sln)    do notepad %f



     I personally don't recommend notepad for any purpose at all.

     I use TextPad http://www.textpad.com/  Notepad++ is also good.



     DevStudio Express 2010 does not have the "Batch Build" feature.

     Select "exiv2" right-click "Set as Startup Project" and

     Select Platform="Win32" Configuration="Debug|DebugDLL|Release|ReleaseDLL"  Build.

     Build the Configurations you need.  Build time is about 2 minutes/Configuration.



     To remove the "memory" of old configurations:

     setbuild.py reset



2    Design



     expat and zlib1.2.5 (and earlier) do not provide 64 bit builds for DevStudio.

     

     The projects provided for zlib1.2.7 support 64 bit builds, however it didn't

     work cleanly for me.  They use different projects for VC9 and VC10.

     They don't provide support for VC8 or 11beta.

     

     I have created build environments for zlib and expat within exiv2/msvc2005.

     I 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-2.1.0 and zlib-1.2.7 that matter.

     The names expat-2.1.0 and zlib-1.2.7 are fixed (and used by the .vcproj files)



     zlib and expat

     exiv2\msvc2005\zlib\zlib.vcproj                          DevStudio files

     ..\..\..\zlib                                            Source code



     exiv2\msvc2005\expat\expat.vcproj                        DevStudio files

     ..\..\..\expat                                           Source code



2.1  Architecture

     There are directories for every component:

     The libraries: zlib, expat, xmpsdk, exiv2lib

     Applications:  exiv2.exe

     Sample Apps:   exifprint.exe, addmoddel.exe and many more (used by test suite)



     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



     Final builds and include directories (for export to "foreign" projects)

     bin\{win32|x64}\Win32\{Debug|Release|DebugDLL|ReleaseDLL} 



2.2  Relationship with msvc2003 build environment

     msvc2005 is similar to msvc2003.

     However there are significant differences:

     1) msvc2005 supports 64 bit and 32 bit builds

     2) msvc2005 provides projects to build expat, zlib, curl, libssh and openssl

     3) msvc2005 is designed to accomodate new versions of expat and zlib when they become available.

     4) msvc2005 supports DevStudio 2005 and later (no support for 2003)

     5) msvc2005 does not require you to build 'vanilla' expat and zlib projects in advance

     6) msvc2005 does not support the organize application

     7) msvc2005 supports building with zlib1.2.7 or 1.2.8 

     7) msvc2005 supports building with expat2.1.0



     msvc2003 will continue to be supported for 32 bit builds using DevStudio 2003/05/08,

     however there is no plan to enhance or develop msvc2003 going forward.



3    Batch builds and tests



3.1  buildall.bat

     This was intended to be a "throw away" kind of script and it's grown to be quite useful.

     You will have to run vcvars32.bat for the compiler you intend to use to ensure devenv is

     on your path.



     It doesn't know anything about building only x64 or only Win32. Change the script if you

     want something special.



3.2  Running the test suite

     You will need to install cygwin to run the test suite.

     

     This is a two stage process:

     Step1:  Build exiv2 for cygwin and run the test suite

             Typical Unix type build:

             make config

             ./configure --disable-visibility

             export PKG_CONFIG_PATH=$PWD/config

             make clean ; make ; make samples ; make install ; cd test ; make test

             

     Step2:  set the environment variable EXIV2_BINDIR appropriately and rerun make test

             export EXIV2_BINDIR=<path-to-directory-with-exiv2.exe>



             I find the following little bash loop very useful.  You should test

             against all the directories in the msvc2005/bin directory:

             for d in $(find /c/gnu.2005/exiv2/msvc2005/bin -name exiv2.exe -exec dirname {} ";"); do

                export EXIV2_BINDIR=$d

                echo ---------------------------------

                echo ---- $d ----

                echo ---------------------------------

                make test

            done

            

     Free gift: (you get what you pay for)

            The script testMSVC.sh to runs this loop for you.

            The script verifyMSVC.sh validates the output of testMSVC.sh

            I've added those for my convenience and I hope you'll find them useful.



     And to pass the time (the test suite takes about an hour to run)

            I recommend running listdlls exiv2.exe occasionally during testing to be confident

            that the test suite is running the MSVC built versions of exiv2 and libraries.

            

            From cygwin:

            while sleep 1 do; listdlls exiv2.exe ; done

            or

            while sleep 10 do ; listdlls exiv2.exe | grep exiv2.exe ; done

            

     Note: Cygwin currently ships diff-utils 2.9.2 which treats binary files differently

     from 2.8.7 (on Mac) and 3.2 (on Ubuntu 12.04).  For this reason, the executable (and

     support dlls) for GNU diff.exe 2.8.7 is provided in msvc2003/diff.exe.

     The test suite has been "doctored" on cygwin to modify the path appropriately to

     use this preferred version of diff.exe.
