[Ramiro Polla]

Hi,

Here goes some stuff I had written on how to set up MSYS+MinGW.

MSYS-1.0.11-2004.04.30-1.exe
- installed to c:\msys

MSYS-1.0.11-20080821-dll.tar.gz
- extracted to c:\msys\bin
- all files overwritten

bash-3.1-MSYS-1.0.11-snapshot.tar.bz2
- extracted
    bash-3.1/bin/bash.exe
    bash-3.1/bin/sh.exe
  to
    c:\msys\bin
- bash.exe overwritten

make-3.81-MSYS-1.0.11-2.tar.bz2

MinGW
$ tar zxfv binutils-2.18.50-20080109-2.tar.gz -C /mingw
$ tar zxfv mingwrt-3.15.1-mingw32-dev.tar.gz -C /mingw
$ tar zxfv mingwrt-3.15.1-mingw32-dll.tar.gz -C /mingw
$ tar zxfv w32api-3.12-mingw32-dev.tar.gz -C /mingw
$ tar xfvj gcc-4.2.4-mingw32.tar.bz2 -C /mingw

I already had a pre-built gcc-4.2.4. You can use gcc-4.2.1-sjlj and
rename files xxx-sjlj.exe to xxx.exe (like gcc, cpp, g++, I don't
remember).

msysDTK-1.0.1.exe
- installed to c:\msys

This is the important part to get M4 working. It must be built for
MSYS, and not for MinGW, so it must use the msysDVLPR package. The
patch is attached in the e-mail.

msysDVLPR
{
    MSYS-1.0.11-2004.04.30-1.exe
    - installed to c:\msysDVLPR
    (yes, I installed it again but to a different path)

    msysDVLPR-1.0.0-alpha-1.tar.gz
    - extracted to c:\msysDVLPR

    open up recently-installed msysDVLPR system
    $ sh msysdvlpr
    close beige window and run the next part in white window

    m4-1.4.12.tar.bz2
    $ tar xfvj m4-1.4.12.tar.bz2
    $ patch -p0 < ../m4-1.4.12-MSYS.diff
    $ cd m4-1.4.12
    $ ./configure
    $ make
    $ cp src/m4.exe /c/msys/bin/m4.exe

    close msysDVLPR
}

autoconf-2.63.tar.bz2
$ tar xfvj autoconf-2.63.tar.bz2
$ cd autoconf-2.63
$ ./configure --prefix=/usr
$ make
$ make install

automake-1.10.2.tar.bz2
$ tar xfvj automake-1.10.2.tar.bz2
$ cd automake-1.10.2
$ ./configure --prefix=/usr
$ make
$ make install

libtool-1.5.26.tar.gz
$ tar zxfv libtool-1.5.26.tar.gz
$ cd libtool-1.5.26
$ ./configure --prefix=/usr
$ make
$ make install

To build gcc-4.2, I think you'll only need to add flex and bison to
the base msys/mingw install. Get them from
http://gnuwin32.sourceforge.net/packages.html and install the .exe
somewhere in your MSYS path. Then unpack the gcc tarball, and do
something like:
$ tar xfvj gcc-core-xxx.tar.bz2
$ cd gcc-xxx
$ mkdir build
$ cd build
$ ../configure --enable-languages=c --prefix=/mingw --disable-nls
--disable-win32-registry --without-x --enable-threads
$ make

I personally prefer appending a suffix to the gcc versions (with
--program-suffix=-4.2.4) so that I can keep many versions around.

Also I install them with:
$ make DESTDIR=/gcc-4.2.4-mingw32 install
so that I can
$ tar cfvj gcc-4.2.4-mingw32.tar.bz2 /gcc-4.2.4-mingw32/*
and rebuild the msys system from scratch (like it was in the
instructions to build m4).
