# libjpeg.SlackBuild
# by Stuart Winter <stuart@armedslack.org> for the Slackware porting Project.
# Heavily based on the original Slackware build script.
# 14-Jun-2004

# Paths to skeleton port's source & real Slackware source tree:
export CWD=$SLACKSOURCE/l/libjpeg
export PORTCWD=$PWD

# Package meta-data:
export PACKAGE=libjpeg
export PKGSERIES=l
export ARCH=${ARCH:=$PORTARCH}
export VERSION=${VERSION:=6b}
export BUILD=${BUILD:=1}

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

# Determine the CFLAGS for the known architectures:
case $PORTARCH in
   armv3)   ARCH_CFLAGS="-O2 -march=armv3 -mtune=xscale" ;;
   powerpc) ARCH_CFLAGS="-O2" ;;
   sparc)   ARCH_CFLAGS="-O2" ;;
   *) ARCH_CFLAGS="-O2" ;;

# Untar source:
tar zxvf $CWD/jpegsrc.v${VERSION}.tar.gz
cd jpeg*

# House keeping:

# Apply patches:
zcat $CWD/jpeg-6b.diff.gz | patch -p0 -E

# Make package framework:
mkdir -p $PKG/usr/{man/man1,include,bin,lib,doc/$PACKAGE-$VERSION}

# Configure & build:
./configure || failconfig
make || failmake

# Install binaries:
install -m755 cjpeg djpeg jpegtran rdjpgcom wrjpgcom \
              $PKG/usr/bin

# Install man pages:
install -m644 cjpeg.1 djpeg.1 jpegtran.1 rdjpgcom.1 wrjpgcom.1 \
              $PKG/usr/man/man1

# Install libraries:
install -m755 libjpeg.so.62.0.0 $PKG/usr/lib
install -m644 libjpeg.a $PKG/usr/lib

# Install headers:
install -m644 jconfig.h jpeglib.h jmorecfg.h jerror.h \
              $PKG/usr/include

# Install docs:
cp -a README *.doc $PKG/usr/doc/$PACKAGE-$VERSION

# Enter the package's root:
cd $PKG

# Slackware policies:
slackstripall   # strip all .a archives and all ELFs
slackgzpages -i # compress man & info pages and delete usr/info/dir
slackslack      # set all files to root.root, chmod -R og-w, slackchown, slack644docs
slackdesc       # install slack-desc and doinst.sh

# Build the package:
if [ $PORTARCH = armv3 ]; then
   . $PORTCWD/arm/pkger
 else
   makepkg -l y -c n $PKGSTORE/$PKGSERIES/$PACKAGE-$VERSION-$ARCH-$BUILD.tgz
fi

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