Hi,
After hours of struggling in the undergrounds of configure and his friends,
I now have a long awaited compiler: cegcc on windows, cygwin free.
I did not use msys to build it, because I was unable to sort out the
libiberty problem. I did a (n in)famous canadian cross build. For those who
want to better known this monster, see [1]
The build was a success with the gcc 4.1 source, as well as the gcc 4.4
source.
The required steps are:
1 build mingw32ce for linux in /opt/mingw32ce. This step is mandatory and
made me loose a lot of time before I understand my error: I was building a
WINDOWS compiler, so linux was unable to build the target libs. ah ah ah
neebie pwnt.
1.bis drink coffee
2 install the mingw cross compiler for your distro, on my debian it was
"sudo apt-get install mingw", or else you can also build it following the
instructions from [3], by asking gcc-4.2.1 (the default settings resulted in
a malfunctional compiler, and I still have issues with a just-built mingw)
3 patch build-mingw32ce.sh with the following little patch [2]
cd (cegcc root dir)
wget
http://www.unsads.com/~squalyl/cegcc/ccbpatch.txt<http://www.unsads.com/%7Esqualyl/cegcc/ccbpatch.txt>
patch -p0 < ccbpatch.txt
this basically adds easy support of the --with-gmp and --with-mpfr for gcc
compilation
3 Add MinGW to your path
4 download gmp and mpfr, build these friends for mingw
mkdir $HOME/mingwlibs
cd $HOME/mingwlibs
wget ftp://ftp.gmplib.org/pub/gmp-4.3.1/gmp-4.3.1.tar.gz
tar zxvf gmp-4.3.1.tar.gz
mkdir build-gmp
cd build-gmp
../gmp-4.3.1/configure --host=i586-mingw32msvc --prefix=$HOME/mingwlibs
make
drink coffee
make install
wget http://www.mpfr.org/mpfr-current/mpfr-2.4.1.tar.gz
tar zxvf mpfr-2.4.1.tar.gz
mkdir build-mpfr
cd build-mpfr
../mpfr-2.4.1/configure --host=i586-mingw32msvc --prefix=$HOME/mingwlibs
--with-gmp=$HOME/mingwlibs
make
drink coffee or use a quadcore build machine and do it in 20 seconds
make install
5 add /opt/mingw32ce/bin to the path
6 build the cross cross compiler using the patched build script to support
additional gcc options:
cd
mkdir $HOME/mingw32ce-win
mkdir $HOME/build-cegcc-cross
cd build-cegcc-cross
host=i586-mingw32msvc HOSTLIBS=$HOME/mingwlibs
../src/scripts/build-mingw32ce.sh --prefix=$HOME/mingw32ce-win
6.bis stop drinking coffee, that's too much for today. Ask your friends if
they know what a canadian cross build is.
7 That's done. You can zip the $HOME/mingw/sysroot directory and unzip it on
your windows box.
Simple, isn't it?
I've attached a binary package that can be unzipped on any win32 box, also
at [2]
I've tried to build haret as a demo, but I first need python.
Regards,
Sebastien
