[pacman-dev] Split installs for makepkg

[Mark Constable]

I'd like any opinion about doing split installs using the
method outlined below. Is this a reasonable approach or am
I missing something obvious?

It seems to work okay and does not involve any hacking or
patching of /usr/bin/makepkg. This example is for building
qt-copy and qt-copy-doc from KDE4 svn trunk using
qt-copy/PKGBUILD as the "parent" PKGBUILD and removing the
build() function from the "child" PKGBUILD.qt-copy-doc and
putting that logic into the parent build_doc() function...

pkgname=qt-copy
pkgver=4.3.3
pkgrel=7
_pkgfqn=qt-x11-opensource-src-$pkgver
... other typical pre build variables

build()
{
  ... pre make instructions

  make || return 1
  build_doc
  ## ie; requires build_examples() + PKGBUILD.qt-copy-examples
  #build_examples
  make INSTALL_ROOT=$startdir/pkg install || return 1

  ... post make instructions
}

build_doc()
{
  mkdir -p $pkgdir/usr/share/doc/qt
  cp -r $srcdir/$_pkgfqn/doc/html/* $pkgdir/usr/share/doc/qt

  cd $startdir
  makepkg --asroot -R -p PKGBUILD.qt-copy-doc
  rm -rf $pkgdir/*
  cd $srcdir/$_pkgfqn
}
