# Ensure base ARM packages are installed first:
slackbasedeps

# Ensure required packages are installed before proceeding:
# We need this version of autoconf to rebuild configure scripts after we've
# patched gcc -- but ONLY if we're building natively.  Scratchbox already has
# this.
# However, if we're *not* applying Debian's diff then we don't need to regenerate
# the configure scripts, thus autoconf2.13 is not required.
# But I always use Debian's diff now, so autoconf-2.13 is always required.
# Note: [03-Jan-05] I think the old scripts have been tidied up, so autoconf-2.13 is
#       no longer required.  I'm not 100% sure, and since it doesn't hurt to have
#       autoconf-2.13 installed temporarily, I'll continue with this for the time being.
#if [ ! -d /scratchbox ]; then
#   slackcheckpkgdeps autoconf2.13 || installpkg $PKGSTORE/../armedslack-extra/packages/autoconf2.13-*tgz
#fi

# Ensure build dependencies.  If we are building with Debian's diff
# (which we always do now for ARMedslack) we need dpkg-architecture
# which is contained within dpkg.  Even if we aren't using Debian source it does not
# hurt to have dpkg installed.
#if [ ! -d /scratchbox ]; then
#   slackcheckpkgdeps dpkg || installpkg $PKGSTORE/../armedslack-extra/packages/dpkg-*.tgz

# Ensure the kernel headers package is installed.  These should always be installed

# headers from Linux 2.4.26.  In the past I have found 2.6 headers break building gcc.

# Compress the build log:

# Taken care of - will automatically package if it finds gcc-gnat
