Cross-build Instructions

From Aleph One Wiki

Here's how to set up a cross-build environment in Linux/Mac OS X, which you can use to build a Windows version of Aleph One

[edit] Intro

• Go to libsdl to find the tool that basically made this possible and relatively easy

[edit] Cross compiler

• Download this to your /tmp directory
• Edit build-cross.sh to match the release candidate versions of mingw found here
• If you're on a Mac, change instances of wget to curl -O in build-cross.sh
• Add --disable-nls to the binutils configure in build-cross.sh
• Run build-cross.sh as root

[edit] cross-configure.sh / cross-make.sh

• Download this and this

[edit] SDL

• Download this
• cross-configure.sh --disable-shared, cross-make.sh install
• cd to /usr/local/cross-tools/i386-mingw32msvc and untar the w32api-2.3.tar.gz file from /tmp/source (this is to fix an opengl problem, I think build-cross.sh untars a couple files in the wrong order)

[edit] SDL_net

• Download, cross-configure --disable-shared and cross-make install SDL_net

[edit] JPEG

• Get the latest JPEG src
• cross-configure.sh --disable-shared --prefix=/usr/local/cross-tools/i386-mingw32msvc
• cross-make.sh install-lib

[edit] zlib

• get zlib
• cross-configure.sh --prefix=/usr/local/cross-tools/i386-mingw32msvc
• cross-make.sh libz.a, cross-make.sh install

[edit] libPNG

• Get the config-based libpng
• cross-configure.sh --prefix=/usr/local/cross-tools/i386-mingw32msvc
• cross-make.sh install

[edit] SDL_image

• get SDL_image
• cross-configure.sh --disable-shared
• cross-make.sh install

[edit] SMPEG

• get SMPEG
• LIBS="-lstdc++" cross-configure.sh --prefix=/usr/local/cross-tools/i386-mingw32msvc --disable-shared
• cross-make.sh install

[edit] SDL_sound

• get the stable SDL_Sound from subversion:

svn co svn://svn.icculus.org/SDL_sound/branches/stable-1.0/ SDL_sound-stable-1.0
cd SDL_sound-stable-1.0
./bootstrap
CFLAGS="-I/usr/local/cross-tools/i386-mingw32msvc/include/smpeg" LIBS="-lstdc++" \
/tmp/cross-configure.sh --disable-shared --prefix=/usr/local/cross-tools/i386-mingw32msvc \
--enable-smpeg --disable-midi --disable-mpglib

 sed -ie s/playsound//g Makefile

• cross-make.sh install

[edit] Speex

• Download and untar Speex
• Cross-configure speex with --prefix=/usr/local/cross-tools/i386-mingw32msvc --enable-ogg=no --disable-shared
• cross-make and install speex

[edit] Lua

• Download Lua
• Edit INSTALL_ROOT to /usr/local/cross-tools/i386-mingw32msvc in the Lua config file
• Cross-configure and cross-make install lua

[edit] Boost

• download a boost-jam executable for your native architecture
• download the boost library itself
• untar boost, put bjam in it, and

./bjam -sTOOLS="gcc" --prefix="/usr/local/cross-tools/i386-mingw32msvc" \ 
--sGXX="/usr/local/cross-tools/i386-mingw32msvc/bin/g++" --with-bind \ 
--with-function install

• ln -s /usr/local/cross-tools/i386-mingw32msvc/include/boost_1_32/boost /usr/local/cross-tools/i386-mingw32msvc/include

[edit] Building Aleph One

• in your aleph directory: sh autogen.sh
• N.B. you need SDL installed in your linux environment, so that the native configure succeeds
• cd Source_Files/Expat and make gennmtab (this is a native make; gennmtab is run to generate nametab.h so it has to be a native binary)
• cd ../.. and LIBS="-ljpeg -lpng -lz -lstdc++ -lws2_32" cross-configure.sh
• cd Source_Files/Expat and make clean
• cd .. and cross-make.sh

[edit] Done

At this point you should have a partially-stripped, static linked AlephOne.exe in your source files directory.
