# Heavily based on the original Slackware build scripts,
# Modified by Stuart Winter <mozes@slackware.com>
# Please see changelog.txt for revisions to this package's build script history.

# Record toolchain & other info for the build log:

# Paths to skeleton port's source & real Slackware source tree:

# Temporary build locations:
export TMPBUILD=$TMP/build-$PKGNAM
export PKG=$TMP/package-$PKGNAM
mkpkgdirs # Delete & re-create temporary directories then cd into $TMPBUILD

# Determine the CFLAGS for the known architectures:
case $ARCH in
   arm)     export SLKCFLAGS="-O2 -march=armv5te"
            export LIBDIRSUFFIX="" ;;

# Build:
# On ARM and any other arch for which svgalib cannot be built (thus not installed)
# you'll see: ppmsvgalib.c:14:17: vga.h: No such file or directory
# But ARMedslack now uses the svgalib-dummy package from Debian as a work-around.

# Install into package:
rm -rf $PKG # otherwise the installation fails; it likes to make the directory itself

# Put things in proper directories:
( cd $PKG
  rm README

  mv VERSION bin/doc.url doc/netpbm-$VERSION

# Even out-of-date manpages are better than nothing.  IMHO.
#( cd $PKG/usr

# Add a documentation directory:

# Apply generic Slackware packaging policies:
cd $PKG
slackstripall   # strip all .a archives and all ELFs
slackgzpages -i # compress man & info pages and delete usr/info/dir
slackslack      # chown -R root:root, chmod -R og-w, slackchown, slack644docs
slackdesc       # install slack-desc and doinst.sh
slackmp         # run makepkg

# Perform any final checks on the package:
cd $PKG
slackhlinks     # search for any hard links
