BUILDING THE TOOLCHAIN

If you are only interested in using Linux/PARISC then please see the software information.

REQUIREMENTS FOR BUILDING THE TOOLCHAIN

  • GCC
  • Binutils
  • Linux
  • Glibc
If you don't want to hack the toolchain then is it easier to grab a precompiled one. See the Cross-compilers section of the software page for info on how to get that.
 
HOW TO BUILD THE TOOLCHAIN
 
The source trees of all of these are available through CVS but we also make available nightly snapshots from here. It is best to get a snapshot the first time you want to build a tree and update from CVS from then on.
  1. Fetch GCC, Binutils, Glibc, Linux:
    cd
    mkdir source
    mkdir build
    cd source
    wget http://cvs.parisc-linux.org/download/binutils-latest.tar.gz
    wget http://cvs.parisc-linux.org/download/get gcc-latest.tar.gz
    wget http://cvs.parisc-linux.org/download/linux-latest.tar.gz
    wget http://cvs.parisc-linux.org/download/glibc-latest.tar.gz
    
    Determine the host system setup:
     
    In the next few steps, you'll be configuring and building the toolchain. It needs to be told the system you'll be hosting (running) the tools on. For Intel-based Linux machines, the name is i386-linux. For HPUX machines with PA-RISC processors, the name is hppa-hpux. For Alpha-based Linux machines, the name is alpha-linux. If you want to host your tools on a different architecture, and can't determine your machine name, let us know. In the instructions which follow, we use $MACH to represent this machine name. You can set this as a shell variable with MACH=i386-linux (in sh) or set MACH i386-linux (in csh). You also need to determine where you want to install it. DEST=/usr/parisc or perhaps DEST=/opt/puffin seem to be popular alternatives. You might also want to leave off the --disable-nls option to configure if you are not a native English speaker.
     
  2. Configure and build Binutils:
    cd ~/source
    zcat binutils-latest.tar.gz | tar -xf -
    cd ~/build
    mkdir binutils
    cd binutils
    ~/source/binutils/configure --host=$MACH --prefix=$DEST --target=hppa-linux\
     --enable-targets=hppa64-linux --disable-nls
    make
    make install
    
  3. Configure and partially build GCC:
    cd ~/source
    zcat gcc-latest.tar.gz | tar -xf -
    cd gcc
    contrib/gcc_update --touch
    cd ~/build
    mkdir gcc
    cd gcc
    # Only build the C compiler at this stage.  We build the rest after glibc.
    ~/source/gcc/configure --host=$MACH --prefix=$DEST --target=hppa-linux\
     --enable-shared --disable-nls --enable-languages=c
    make
    make install
    
  4. Unpack and configure the kernel:
    cd ~/source
    zcat linux-latest.tar.gz | tar -xf -
    cd linux
    make oldconfig
    # This step is necessary to build header files that glibc needs.
    make dep
    
  5. Configure and build glibc
    cd ~/source
    zcat glibc-latest.tar.gz | tar -xf -
    cd ~/build
    mkdir glibc
    cd glibc
    # Yes, --host and --prefix options are different here.  That's because we are
    # compiling glibc for our target machine.  This glibc "runs on" hppa-linux.
    # BEWARE, I had problems with --with-headers and had to specify a full path
    # rather than using '~'.
    ~/source/glibc/configure --host=hppa-linux --build=$MACH\
     --prefix=$DEST/hppa-linux --with-headers=$HOME/source/linux/include\
     --disable-profile --without-cvs --enable-add-ons
    make
    make install
    cd $DEST/hppa-linux/include
    ln -s ~/source/linux/include/linux .
    ln -s ~/source/linux/include/asm .
    
  6. Reconfigure and fully build GCC:
    cd ~/build/gcc
    ~/source/gcc/configure --host=$MACH --prefix=$DEST --target=hppa-linux\
     --enable-shared --disable-nls
    make
    make install
    

That's it!
