Today, I heard from Mark Summerfield

Hi Steven,

I’ve just released DiffPDF 1.2.0.

There are small improvements in the user interface plus a tiny bug fix
of one setting that wasn’t saved/restored correctly.

I am hoping that this will be the last release for quite a while!

I’d be very grateful if you’d create a statically built Windows version:
your build for 1.1.5 is proving very popular!

Thanks:-)

So I compiled and released it in the first time, feel free to download it here

P.S. Change logs

On November 18, 2010, I recommend diffpdf-an open source PDF compare software

On March 19, 2011, Diffpdf 1.1.4 Dev Test 1 released by Simeon

and Today, Mar 31 ,2011, New: Diffpdf Portable 1.1.4 (PDF file comparison) Released

Many thanks to

Mark Summerfield, he develops such a great software

Simeon, he made the portable version

btw, DiffPDF 1.1.5 Win32 version is also out, looking forward the portable version.

DiffPDF Portable Release News Screen shot

I tried many times to compile Podofo 0.9 and svn trunk under Windows 7 + MinGW32, but always failed(I have successfully compiled static and shared version PoDoFo 0.84 under the same environment). So I decided to do the job under Linux with MinGW cross compiling environment.
After the job, Build MinGW Cross Compiling Environment under Debian Lenny, very first time, I tried to compile PoDoFo 0.9 and svn trunk(r1445), and finally both succeed.
download and unpack
wget http://ncu.dl.sourceforge.net/project/podofo/podofo/0.9/podofo-0.9.0.tar.bz2
tar jxf podofo-0.9.0.tar.bz2
Compile Win32 Static Version
mkdir podofo-0.9.0-win32-static
cd podofo-0.9.0-win32-static
cmake -DCMAKE_TOOLCHAIN_FILE=/opt/mingw/usr/i686-pc-mingw32/share/cmake/mingw-cross-env-conf.cmake ../podofo-0.9.0 -DFREETYPE_INCLUDE_DIR_FT2BUILD:PATH=/opt/mingw/usr/i686-pc-mingw32/include/freetype2 -DFREETYPE_INCLUDE_DIR_FTHEADER:PATH=/opt/mingw/usr/i686-pc-mingw32/include -DFREETYPE_LIBRARY_RELEASE:FILEPATH=/opt/mingw/usr/i686-pc-mingw32/lib/libfreetype.a -DWIN32=1 -DCMAKE_INSTALL_PREFIX:PATH=/root/podofo-0.9.0-win32-static
make
make install

Maybe because of the bug of the podofo-0.9.0/cmake/modules/FindFREETYPE.cmake, I had to explicit add the freetype info to cmake, if you execute the following command,
cmake -DCMAKE_TOOLCHAIN_FILE=/opt/mingw/usr/i686-pc-mingw32/share/cmake/mingw-cross-env-conf.cmake ../podofo-0.9.0-win32-static -DWIN32=1 -DCMAKE_INSTALL_PREFIX:PATH=/root/podofo-0.9.0-win32-static
you will get the following error message, even though you have already installed FreeType correctly,

CMake Error at /usr/share/cmake-2.6/Modules/FindPackageHandleStandardArgs.cmake:52 (MESSAGE):

Call Stack (most recent call first):

CMakeLists.txt:354 (FIND_PACKAGE)

and because Linux is case sensitive, so I got the following two error messages,

from the message, I know it need Jpeg library, checking podofo-0.9.0-win32-static/tools/podofoimg2pdf/CMakeFiles/podofoimg2pdf.dir/link.txt

it already includes libjpeg.a, I do not know why, but have to append some code to let it works, and finally the content of link.txt is as following,
/opt/mingw/usr/bin/i686-pc-mingw32-g++ -O3 -DNDEBUG CMakeFiles/podofoimg2pdf.dir/podofoimg2pdf.cpp.obj CMakeFiles/podofoimg2pdf.dir/ImageConverter.cpp.obj -o podofoimg2pdf.exe -Wl,--out-implib,libpodofoimg2pdf.dll.a -Wl,--major-image-version,0,--minor-image-version,0 -L/opt/test/podofo-win32/src -lpodofo /opt/mingw/usr/i686-pc-mingw32/lib/libz.a /opt/mingw/usr/i686-pc-mingw32/lib/libjpeg.a -lpthread -lkernel32 -luser32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 -lole32 -loleaut32 -luuid -lWS2_32 /opt/mingw/usr/i686-pc-mingw32/lib/libfreetype.a /opt/mingw/usr/i686-pc-mingw32/lib/libpng.a /opt/mingw/usr/i686-pc-mingw32/lib/libz.a /opt/mingw/usr/i686-pc-mingw32/lib/libjpeg.a -lpthread -lkernel32 -luser32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 -lole32 -loleaut32 -luuid -lWS2_32 /opt/mingw/usr/i686-pc-mingw32/lib/libfreetype.a /opt/mingw/usr/i686-pc-mingw32/lib/libpng.a -L/opt/mingw/usr/i686-pc-mingw32/lib -ltiff -ljpeg -lz .
and now, the Win32 static version PoDoFo 0.9.0 created and installed into /root/podofo-0.9.0-win32-static folder.
To compile shared version, we need do some modification, by default, /opt/mingw/usr/i686-pc-mingw32/share/cmake/mingw-cross-env-conf.cmake has set BUILD_SHARED_LIBS option as OFF, so you need set it ON
mkdir podofo-0.9.0-win32-shared
cd podofo-0.9.0-win32-shared
cmake -DCMAKE_TOOLCHAIN_FILE=/opt/mingw/usr/i686-pc-mingw32/share/cmake/mingw-cross-env-conf.cmake ../podofo-0.9.0 -DFREETYPE_INCLUDE_DIR_FT2BUILD:PATH=/opt/mingw/usr/i686-pc-mingw32/include/freetype2 -DFREETYPE_INCLUDE_DIR_FTHEADER:PATH=/opt/mingw/usr/i686-pc-mingw32/include -DFREETYPE_LIBRARY_RELEASE:FILEPATH=/opt/mingw/usr/i686-pc-mingw32/lib/libfreetype.a -DWIN32=1 -DCMAKE_INSTALL_PREFIX:PATH=/root/podofo-0.9.0-win32-shared -DBUILD_SHARED_LIBS:BOOL=TRUE -DPODOFO_BUILD_SHARED=1
make
make install

and when Creating library file: libpodofo.dll.a will get the same error as podofoimg2pdf, and the solution is also same.
