Cross compiling

After a couple of days of hard work I was able to build one cross compiler hosted on i686 Linux and targetted for Sparc Solaris.
Although it was quite straightforward in principle it required some Solaris packages to be unpacked in order to obtain all the headers and libraries I needed for compilation

The packages I used were SUNWhea, SUNWlibC, SUNWlibm.
I needed also the PThread library in order to build libgomp.
In order to get their content unpack the none.bz2 from each one with the command

$ bzcat none.bz2  cpio -C 512 -idu

I have then downloaded gcc-4.2.2 and binutils-2.17.
In order to build it I have used this script:

#!/bin/bash

export TARGET=sparc-sun-solaris2.10
export BUILD=x86_64-unknown-linux-gnu

export PREFIX=`pwd`/$TARGET
export SRC=`pwd`/src
export BINUTILS=binutils-2.17
export GCC=gcc-4.2.0

export PATH=$PREFIX/bin:$PATH

INCLUDE=`pwd`/src/$TARGET/include
LIBS=`pwd`/src/$TARGET/lib

init ()
{
        mkdir -p $PREFIX
        mkdir -p build
}

binutils ()
{
        mkdir build/$BINUTILS
        cd build/$BINUTILS
        $SRC/$BINUTILS/configure \
            --prefix=$PREFIX \
            --target=$TARGET \
            --with-gnu-as \
            --with-gnu-ld \
            --disable-nls \
            --with-headers=$INCLUDE \
            --with-libs=$LIBS
        make all install
        cd ..
}

gcc ()
{
        #export CC=$TARGET-gcc
        #export PATH=$PREFIX/$TARGET/bin:$PATH
        #export LD_LIBRARY_PATH=$PREFIX/$TARGET/lib
        mkdir build/$GCC
        cd build/$GCC
        $SRC/$GCC/configure \
            --prefix=$PREFIX \
            --target=$TARGET \
            --enable-languages=c,c++ \
            --disable-nls \
            --with-gnu-as \
            --with-gnu-ld \
            --with-headers=$INCLUDE \
            --with-libs=$LIBS
        make all install
        cd ..
}

init
binutils
gcc

Afterwards I was able to compile a simple hello world with the newly generated compiler. It felt good... Mission accomplished...

Still I am not quite okay with the size of the includes and libraries used - I had to do some tricks in order to build them. The cleanest solution would be to install a fresh system and take the files directly from there.
