Because my  MinGW Cross Compiling Environment includes compiled Qt4, after successfully compiled poppler-0.6.13 (with the Poppler Qt4 interface library, libpoppler-qt4), I decided to compile the last version of DiffPDF, after some effort, the Win32 Static version is out, is only 4M an only one exe file, without any library.

Feel free to download the last version from DiffPDF Win32 binary download page.

P.S. Change log of  1.1.5,

Slightly changed the .pro file to make it a tiny bit more helpful.

Added a Help button and separated Help and About information.

Updated the README for Mac users (thanks to Dirk Loss for the info).

In my previous article, LibJpeg vs LibJpeg-turbo, libjpeg-turbo is a fork of libjpeg that uses SIMD instructions to accelerate JPEG encoding and decoding, so I decide to replace libjpeg with libjpeg-turbo on my MinGW cross compiling environment, and here is the step.


wget http://downloads.sourceforge.net/project/libjpeg-turbo/1.1.0/libjpeg-turbo-1.1.0.tar.gz
tar zxf libjpeg-turbo-1.1.0.tar.gz
cd libjpeg-turbo-1.1.0
./configure --host=i686-pc-mingw32 --enable-static --disable-shared --prefix=/opt/mingw/usr/i686-pc-mingw32
make
make install

if you have not install nasm, you will get the following message,
checking for nasm... no
checking for nasmw... no
configure: error: no nasm (Netwide Assembler) found
then you need install nasm,
apt-get install nasm
and repeat
./configure --host=i686-pc-mingw32 --enable-static --disable-shared --prefix=/opt/mingw/usr/i686-pc-mingw32
make
make install

That is all.

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):

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

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,

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.
