Building Cygwin cross compilation tools for Linux 
Edit
Cygwin as cross platform is currently not usable. Version 0.6.3 and later use mingw32 on Linux. Please read doc/building in source, and run the Linux typical commands ./configure && make
Even though Cygwin isn't the proper build environment for coLinux anymore, it's can still be useful for other purposes and these were some of the best directions around to setup this environment, so I've updated them to use current versions.
First, choose an installation directory, for example: /usr/local/cygwin. I'd refer to that directory as $PREFIX from this point in the document. You'll also need a temporary directory to execute this procedure (e.g. /tmp/cygbuild).
Download the Cygwin tarballs listed below from cygwin.com, or from http://mirrors.xmission.com/cygwin/release/cygwin. NOTE: the version numbers of the various downloaded tarballs below are for example only. You'll find that newer versions of these files are now available.
cygwin-1.7.7-1.tar.bz2 w32api-3.15-1.tar.bz2 libiconv-1.13.1-2.tar.bz2
Extract the tarballs in your build directory in this manner and move them into $PREFIX:
tar xjf cygwin-1.7.7-1.tar.bz2 usr/lib usr/include usr/bin
tar xjf w32api-3.15-1.tar.bz2 usr/lib usr/include
tar xjf libiconv-1.13.1-2.tar.bz2 usr/lib usr/include
mkdir -p $PREFIX
mv usr $PREFIX/i686-pc-cygwin
Now you have a ready $PREFIX/i686-pc-cygwin directory.
Download the source of the latest binutils: http://ftp.gnu.org/gnu/binutils/. Extract, configure, build, install.
tar -xzf binutils-2.21.tar.gz cd binutils-2.21 ./configure --target=i686-pc-cygwin --prefix=$PREFIX make make install
Download the latest gcc sources from ( http://gcc.gnu.org/mirrors.html ). Extract them and build gcc using this procedure:
tar xjf ~/dload/cygcross/gcc-4.5.2.tar.bz2
mkdir obj-gcc
cd obj-gcc
../gcc-4.5.2/configure --target=i686-pc-cygwin --prefix=$PREFIX --with-newlib --enable-languages=c,c++
make
make install
Here's the previous version of these directions, using GCC 3.3.4:
First, choose an installation directory, for example: /usr/local/w32build. I'd refer to that directory as $PREFIX from this point in the document.
Download the latest base cygwin tarball from cygwin.com, or from http://mirrors.xmission.com/cygwin/release/cygwin. NOTE: the version numbers of the various downloaded tarballs below are for example only. You'll find that newer versions of these files are now available.
Extract that tarball to the installation directory in this manner:
tar -xjf cygwin-1.5.7-1.tar.bz2
mv usr i686-pc-cygwin
Now you have a ready $PREFIX/i686-pc-cygwin directory.
Download the source of the latest binutils: http://ftp.gnu.org/gnu/binutils/. Extract, configure, build, install.
tar -xzf binutils-2.15.tar.gz cd binutils-2.15 ./configure --target=i686-pc-cygwin --prefix=$PREFIX make make install
Download the w32api package from www.mingw.org ( http://www.mingw.org/download.shtml ), and install it under $PREFIX in this manner:
mkdir w32api tar -C w32api -zxf w32api-2.3.tar.gz mv w32api/include i686-pc-cygwin/include/w32api mv w32api/lib i686-pc-cygwin/lib/w32api rmdir w32api
Download the latest gcc sources, both the gcc-core and gcc-g++ parts ( http://gcc.gnu.org/mirrors.html ). Extract those in a separate directory, and build gcc using this procedure:
tar -jxf gcc-core-3.3.4.tar.bz2 tar -jxf gcc-g++-3.3.4.tar.bz2 cd gcc-3.3.4 ./configure --prefix=$PREFIX --target=i686-pc-cygwin --enable-languages=c,c++ make make install
