MINGW32 from scratch

Setting up the toolchain

I prefer to place the crosscompiler in /opt/win32

create the directory as root:

 sources$ install -d /opt/win32 -m 777

binutils-2.18.50

Build:

 sources$ tar -xf binutils-2.18.50-20080109-2-src.tar.gz 
 sources$ mkdir build
 sources$ cd build
 sources/build$ ../binutils-2.18.50/configure --target=mingw32 --prefix=/opt/win32 --disable-nls
 sources/build$ make tooldir=/opt/win32

Install as root:

 sources/build$ make tooldir=/opt/win32 install

Cleanup our mess:

 sources/build$ cd ..
 sources$ rm -frd build

To build gcc, certain headers are needed.

w32api-3.11 part 1

Unpack:

 sources$ tar -xf w32api-3.11-src.tar.gz

Install as root:

 sources$ cp -r w32api-3.11/include /opt/win32

mingw-runtime-3.14 part 1

Unpack:

 sources$ tar -xf mingw-runtime-3.14-src.tar.gz

Install as root:

 sources$ cp -r mingw-runtime-3.14/include /opt/win32

The compiler

gcc 4.3.1 needs gmp and mpfr as dependency, since I don't have these packages already on
my system I needed to install them. I use LFS and there everything is stored in /usr instead
of /usr/local so I have to use --prefix=/usr

gmp-4.2.2

Build:

 sources$ tar -xf gmp-4.2.2.tar.gz
 sources$ mkdir build
 sources$ cd build
 sources/build$ ../gmp-4.2.2/configure --prefix=/usr --enable-cxx --enable-mpbsd
 sources/build$ make

Install as root:

 sources/build$ make install

Cleanup our mess:

 sources/build$ cd ..
 sources$ rm -frd build

mpfr-2.3.1

Build:

 sources$ tar -xf mpfr-2.3.1.tar.gz  
 sources$ mkdir build
 sources$ cd build
 sources/build$ ../mpfr-2.3.1/configure --prefix=/usr
 sources/build$ make

Install as root:

 sources/build$ make install

Cleanup our mess:

 sources/build$ cd ..
 sources$ rm -frd build

gcc 4.3.1 part 1

Build:

 sources$ tar -xf gcc-4.3.1.tar.gz
 sources$ mkdir build
 sources$ cd build
 sources/build$ ../gcc-4.3.1/configure --prefix=/opt/win32 --target=mingw32 --enable-languages=c \
 --with-headers=/opt/win32/include
 sources/build$ make

Install as root:

 sources/build$ make install

Cleanup our mess:

 sources/build$ cd ..
 sources$ rm -frd build

Now we have a minimalistic cross compiler. We only need to let it be found.
So add it to our path: (You should edit your scripts to make it permanent.)

 sources$ PATH=$PATH:/opt/win32/bin:

With this compiler we can build the necessary API and runtime, which at their turn are
needed to build the complete compiler.

w32api-3.11 part 2

Build:

 sources$ mkdir build
 sources$ cd build
 sources/build$ ../w32api-3.11/configure --host=mingw32 --prefix=/opt/win32
 sources/build$ make

Install as root:

 sources/build$ make install

Cleanup our mess:

 sources/build$ cd ..
 sources$ rm -frd build

mingw-runtime-3.14 part 2

Build:

 sources$ ln -s w32api-3.11 w32api 
 sources$ mkdir build
 sources$ cd build
 sources/build$ ../mingw-runtime-3.14/configure --host=mingw32 --prefix=/opt/win32
 sources/build$ make

Install as root:

 sources/build$ make install

Cleanup our mess:

 sources/build$ cd ..
 sources$ rm -frd build

gcc 4.3.1 part 2

Build:

 sources$ mkdir build
 sources$ cd build
 sources/build$ ../gcc-4.3.1/configure --prefix=/opt/win32 --target=mingw32 --enable-languages=c,c++ \ 
 --with-headers=/opt/win32/mingw32/include --enable-threads --disable-nls --disable-shared \
 -without-x --disable-win32-registry --enable-hash-synchronization --enable-sjlj-exceptions \
 --enable- libstdcxx-debug
 sources/build$ make

Install as root:

 sources/build$ make install

Cleanup our mess:

 sources/build$ cd ..
 sources$ rm -frd build
