HOWTO build i386-linux toolchain for Generic i386/Linux
-------------------------------------------------------


1. Packages used:

    binutils-2.17.tar.gz
    gcc-4.2.1.tar.gz
    glibc-2.3.6.tar.gz


2. binutils-2.17

   tar xvzf binutils-2.17.tar.gz
   cd binutils-2.17
   mkdir i386-linux
   cd i386-linux
   ../configure --target=i386-linux
   make
   make install


3. gcc-4.2.1

   tar xvjf gcc-4.2.1.tar.bz2
   cd gcc-4.2.1
   cp $(ATTACHED t-linux file) gcc/config/
   mkdir i386-linux
   cd i386-linux
   ../configure --target=i386-linux --disable-shared --disable-threads \
	--disable-libmudflap --disable-libssp --prefix=/usr/local \
	--with-headers=<path>/linux-2.6.x/include \
	--enable-languages=c
   make
   [ ignore final build error ]
   make install

4. glibc-2.3.6

   tar xvzf glibc-2.3.6.tar.gz
   cd glibc-2.3.6
   tar xvzf glibc-linuxthreads-2.3.6.tar.gz
   rm -rf nptl
   mkdir i386-linux

   vi Makeconfig
      - remove any usage occurrances of -lgcc_eh
   vi sysdeps/unix/sysv/linux/bind.S
      - comment out line 5 "weak_alias (bind, __bind)"
   vi sysdeps/unix/sysv/linux/getsockname.S
      - comment out line 5 "weak_alias (getsockname, __getsockname)"
   vi sysdeps/unix/sysv/linux/listen.S
      - comment out line 5 "weak_alias (listen, __listen)"
   vi sysdeps/unix/sysv/linux/setsockopt.S
      - comment out line 5 "weak_alias (setsockopt, __setsockopt)"

   cd i386-linux

   CC=i386-linux-gcc \
   AS=i386-linux-as \
   LD=i386-linux-ld \
   ../configure --host=i386-linux --build=i686-pc-linux-gnu \
	--with-headers=<path>/linux-2.6.x/include \
	--enable-add-ons --with-tls --without-__thread \
	--enable-shared --prefix=/usr/local/i386-linux
   make
   make install

5. gcc-4.2.1 (c++, etc)

   tar xvjf gcc-4.2.1.tar.bz2
   cd gcc-4.2.1
   cp $(ATTACHED t-linux file) gcc/config/

   vi gcc/config/t-linux
     - remove "-Dinhibit_libc" -- all occruances
   perl -pi -e 's/int namelen/unsigned int namelen/' ../libjava/java/net/natInetAddressPosix.cc

   mkdir i386-linux
   cd i386-linux
   ../configure --target=i386-linux --disable-shared --prefix=/usr/local \
	--with-headers=<path>/linux-2.6.x/include
   make
   make install


6. packaging

   cd /
   find /usr/local/i386-linux -name CVS -type d | xargs rm -rf
   strip /usr/local/i386-linux/bin/*
   strip /usr/local/bin/i386-linux-*
   strip /usr/local/libexec/gcc/i386-linux/4.2.1/*
   tar cvzf /tmp/i386-linux-tools-xxxxxxxx.tar.gz
        /usr/local/i386-linux \
        /usr/local/lib/gcc/i386-linux \
        /usr/local/libexec/gcc/i386-linux \
        /usr/local/bin/i386-linux-* \
        /usr/local/bin/genext2fs
