[CLUE-Cert] LFS build program

[Dennis J Perkins]

I've done some more thinking about how to do this.  The idea of using 
keyword/parameter pairs is good but insufficient in shell scripts.  I 
think it will work fine using XML.  But I think it is premature to 
consider XML at this time.

The reason the first approach won't work is that some packages need 
commands like sed, cp, ln, etc. applied.  In a few cases, a series of 
commands are needed.  The result starts looking like a shell script 
again.  Rock Linux uses shell scripts to build itself, so I looked at it 
to see what it does.  It also uses shell scripts, called conf files, 
that set variables.  Some variables contain functions.

Here is a quick idea on how binutils might be built.


# binutils.conf

confoptions="--disable-nls"
makeflags="LDFLAGS=--all-static"
builddir=y
patches=binutils-2.13.patch


A quick and dirty (and untested!) build function example in the build 
engine.

build() { # $1=package.conf

    source $1

    for patch in $patches
    do
        patch $patchflags $patch
    done

    if [ $builddir = "y" ]; then
        bdir=${srcdir}-build
        test -d $bdir  && rm -rf $bdir
        mkdir $bdir
        cd $bdir
    else
        cd $srcdir
    fi


    # Run preconfigure function in conf file if it exists.
    eval $preconfigure

    if [ -z $bdir ]; then
        ./configure $confoptions --prefix=$prefix
    else
        ../${srcdir}/configure $confoptions --prefix=$prefix
    fi

    # Run anything that needs to be run prior to running make.
    $premake

    make $makeflags $makeoptions

    make check

    # Run anything that needs to be done after running make.
    eval $postmake

    make install $makeinstalloptions
}
  

Some metainformation about binutils might be useful
