WINDOWS

Cross-compiling from Linux to Windows 32bit and 64bit is possible. The following is tested on (amd64) Debian Wheezy with some packages from Jessie. These pacakges are needed for sure, but others might be too: 

sudo aptitude install \
  mingw-w64 \
  mingw-w64-tools

For testing in wine, I installed libgl1-nvidia-glx:i386 as well (depends on your system if this is appropriate).

The build system assumes all your win32 and win64 stuff is in ~/win32 and ~/win64 so first that needs to get set up: 

mkdir ~/win32 ~/win32/bin ~/win32/src ~/win64 ~/win64/bin ~/win64/src

Then you need to install the dependencies:

GMP

GMP cross-compiles without any problems: 

cd ~/win32/src
wget https://gmplib.org/download/gmp/gmp-6.0.0a.tar.lz
tar xf gmp-6.0.0a.tar.lz
cd gmp-6.0.0
./configure --prefix=${HOME}/win32 --host=i686-w64-mingw32 --enable-cxx
make -j6
make install
cd ~/win64/src
cp -ai ~/win32/src/gmp-6.0.0a.tar.lz .
tar xf gmp-6.0.0a.tar.lz
cd gmp-6.0.0
./configure --prefix=${HOME}/win64 --host=x86_64-w64-mingw32 --enable-cxx
make -j6
make install

MPFR

MPFR also cross-compiles without any problems after you have GMP built: 

cd ~/win32/src
wget http://www.mpfr.org/mpfr-current/mpfr-3.1.2.tar.xz
wget http://www.mpfr.org/mpfr-current/allpatches
cp -ai allpatches mpfr-3.1.2.patch
tar xf mpfr-3.1.2.tar.xz
cd mpfr-3.1.2
patch -N -Z -p1 < ../mpfr-3.1.2.patch
./configure --prefix=${HOME}/win32 --host=i686-w64-mingw32 --with-gmp-build=${HOME}/win32/src/gmp-6.0.0
make -j6
make install
cd ~/win64/src
cp -ai ~/win32/src/mpfr-3.1.2.tar.xz .
cp -ai ~/win32/src/allpatches mpfr-3.1.2.patch
tar xf mpfr-3.1.2.tar.xz
cd mpfr-3.1.2
patch -N -Z -p1 < ../mpfr-3.1.2.patch
./configure --prefix=${HOME}/win64 --host=x86_64-w64-mingw32 --with-gmp-build=${HOME}/win64/src/gmp-6.0.0
make -j6
make install

GLEW

GLEW has binaries for windows, but the download page has a countdown with lots of annoying adverts:

http://sourceforge.net/projects/glew/files/glew/1.11.0/glew-1.11.0-win32.zip/download

Download it to ~/win32/src, then: 

cd ~/win32/src
unzip glew-1.11.0-win32.zip
cd glew-1.11.0
cp -ai lib/*/Win32/*.lib ~/win32/lib
cp -ai bin/*/Win32/*.dll ~/win32/bin
cp -ai bin/*/Win32/*.exe ~/win32/bin
cp -ai include/GL ~/win32/include
cd ~/win64/src
cp -ai ~/win32/src/glew-1.11.0-win32.zip .
unzip glew-1.11.0-win32.zip
cd glew-1.11.0
cp -ai lib/*/x64/*.lib ~/win64/lib
cp -ai bin/*/x64/*.dll ~/win64/bin
cp -ai bin/*/x64/*.exe ~/win64/bin
cp -ai include/GL ~/win64/include

GLFW

GLFW also has windows binaries, also with countdown and annoying adverts:

http://sourceforge.net/projects/glfw/files/glfw/3.0.4/glfw-3.0.4.bin.WIN32.zip/download

http://sourceforge.net/projects/glfw/files/glfw/3.0.4/glfw-3.0.4.bin.WIN64.zip/download

Download them to ~/win32/src and ~/win64/src respectively, then: 

cd ~/win32/src
unzip glfw-3.0.4.bin.WIN32.zip
cd glfw-3.0.4.bin.WIN32
cp -ai lib-mingw/* ~/win32/lib
cp -ai include/GLFW ~/win32/include
cd ~/win64/src
unzip glfw-3.0.4.bin.WIN64.zip
cd glfw-3.0.4.bin.WIN64
cp -ai lib-mingw/* ~/win64/lib
cp -ai include/GLFW ~/win64/include

Building mightymandel.exe

Now you can build mightymandel.exe. To build the 32bit version: 

cd ~/code/mightymandel # or where you downloaded mightymandel
cd src
make -f Makefile.win32 clean
make -f Makefile.win32

To build the 64bit version: 

cd ~/code/mightymandel # or where you downloaded mightymandel
cd src
make -f Makefile.win64 clean
make -f Makefile.win64

If you installed the dependencies in a different location, you can: 

make -f Makefile.win32 WIN32PREFIX=/some/path

or 

make -f Makefile.win64 WIN64PREFIX=/some/path

If wine is set up correctly, you should be able to run it: 

./mightymandel.exe

Bugs in mightymandel.exe

  • localtime_r() isn't working, so I ifdef'd that out. All saved files have the same stem, so be aware that each mightymandel session will overwrite PPM saved from a previous session: 
    NOTICE  saved: mightymandel_1900-01-00_00-00-00_0000_00_00.ppm
  • I don't know what happens on real windows wrt stderr or stdout messages.
  • I don't know what happens on real windows wrt current working directory of a program started by a double click on an icon. So images could get saved to strange places (or saving could fail due to permission issues).
  • 1926 lines of error messages are printed on stderr at launch (this may be an issue with wine instead of mightymandel.exe). 
    err:wgl:is_extension_supported No OpenGL extensions found, check if your OpenGL setup is correct!
