# MinGW DOSBox-X Build Notes
#
# * MinGW redistributable files must be in the PATH while compiling and while
# running a MinGW DOSBox-X. (SDL.dll, libpng.dll, zlib1.dll, etc.)
#
# * The MinGW PNG package does not currently bundle the libpng.dll.a static
# library, which means that a MinGW DOSBox-X cannot be statically compiled using
# distro packages.
#
# Use this environment for building a 64-bit MinGW DOSBox-X on Cygwin:

TRIPLET=x86_64-w64-mingw32
export PATH="/usr/$TRIPLET/sys-root/mingw/bin:$PATH"
export CC="$TRIPLET-gcc"
export CXX="$TRIPLET-g++"

# autoreconf && ./configure && make

# Alternatively install MSYS2 on Windows,
# Open the MSYS2 MinGW 64-bit prompt,
# then run:
pacman -Syu # Keep up to date!
pacman -S base-devel gcc mingw-w64-x86_64-toolchain mingw-w64-x86_64-SDL2 mingw-w64-x86_64-libpng --needed
cd /path/to/dosbox-code
./build-mingw-sdl2
