## Build script for: ngrep
## Creator: kaneda@bohater.net <http://kaneda.bohater.net/slackware>
## Date: 12 Dec 04
## Builds package: Yes
## Source location: http://ngrep.sourceforge.net/
## Downloads Source: Yes
## Build script version: 1.0
## Requirements: None
##
## Notes: Any special notes the person may need to edit this file.
##

## Include the slackware-pkg conf file
if [ -a /etc/slack-package.conf ]; then
. /etc/slack-package.conf
  else
  echo "Sorry you need to have the slack-package.conf file to run these"
  echo "please install the slackbuilds package from LinuxPackages.net"
  exit
fi


## Lets set the name of the program here so we can use it later.
NAME=ngrep

## Set the versions for packages here, these must match the source file version.
PROGRAM_VER=1.44

## Set the BUILD the $MYIN comes from the global config file in /etc
BUILD=1$MYIN

## Location to download the source
SRC_LOC="http://switch.dl.sourceforge.net/sourceforge/ngrep/$NAME-$PROGRAM_VER.tar.bz2"

## Set initial variables these should be standard in most packages:
PKG=$TMP/package-$NAME

## Now we go grab the source for the user. Again global config has the wget line
## We will check if it is here and if not then download
if [ -a $CWD/$NAME-$PROGRAM_VER.tar.bz2 ]; then
echo "Source present not downloading"
else
$WGET $SRC_LOC || true
fi

## Ok time to make sure the area is clean and unarchive the file
rm -rf $PKG
mkdir -p $PKG
cd $TMP
rm -rf $NAME-$PROGRAM_VER
tar jxvf $CWD/$NAME-$PROGRAM_VER.tar.bz2


## Now from this point on we do all the package prep and building. I like to organize them in sections
## like compile, prepare, description, build like below as an example

compile() {
cd $TMP/$NAME-$PROGRAM_VER
chown -R root.root .
if [ ! -f /usr/lib/gcc-lib/i486-slackware-linux/3.2.3/include/net/bpf.h ] && \
[ ! -f /usr/include/net/bpf.h ] ; then
  ln -s /usr/include/pcap-bpf.h /usr/include/net/bpf.h
fi

export CFLAGS=$SLKCFLAGS
./configure --prefix=/usr --mandir=/man
make
make install DESTDIR=$PKG
}

## The next area I use for getting the documents set and maybe config files.

prepare() { 
mkdir -p $PKG/usr/doc/$NAME-$PROGRAM_VER
cp -fr $TMP/$NAME-$PROGRAM_VER/doc/* $PKG/usr/doc/$NAME-$PROGRAM_VER/
cp -fr $TMP/$NAME-$PROGRAM_VER/scripts/ $PKG/usr/doc/$NAME-$PROGRAM_VER/
mv -f $PKG/usr/share/man $PKG/usr/man
rm -rf $PKG/usr/share/

##Some functions from the global config to help with the cleanup
( cd $PKG 
strip_bin

# Strips the libs files reduces the size and removes unneeded cruft
strip_lib
)

# Every good package should gzip those man pages
gzip_man $PKG 

# Set group ownership for the bin directory
bin_perms $PKG

# Set group ownership for the sbin directory
#sbin_perms $PKG

}

## The next area is for the description. You can use this method or just cat a slack-desc file into
## the install area. I will use apache here as a sample

description() {
mkdir -p $PKG/install 
cat > $PKG/install/slack-desc << END

ngrep: $NAME $PROGRAM_VER (network grep)
ngrep:
ngrep: ngrep strives to provide most of GNU grep's common features, applying
ngrep: them to the network layer. ngrep is a pcap-aware tool that will allow
ngrep: you to specify extended regular or hexadecimal expressions to match
ngrep: against data payloads of packets. It currently recognizes IPv4/6, TCP,
ngrep: UDP and ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token
ngrep: Ring and null interfaces, and understands bpf filter logic in the same
ngrep: fashion as more common packet sniffing tools, such as tcpdump and
ngrep: snoop.

END
}

## The last part is the build

build() {
# Build the package:
cd $PKG
makepkg -l y -c n $TMP/$NAME-$PROGRAM_VER-$ARCH-$BUILD.tgz
mv $TMP/$NAME-$PROGRAM_VER-$ARCH-$BUILD.tgz $PKG_DIR/

echo "Your $NAME package is complete, make sure you open it up before installing it."
echo "It is located in $PKG_DIR thanks for your support The Linuxpackages.net Folks"
}

### Now we call all those functions in order
compile
prepare
description
build
