Use LibSVM in WEKA in an Archlinux box

I found both WEKA and libSVM in AUR, however, neither maintainer considered that a user might use them together... It seem we Archie got to work it out ourselves, so here is what I did:

Dowload WEKA tarball from AUR, and Change weka.sh to

#! /bin/sh
# Note: the '-Xmx256m' flag is used to set the maximum memory that the java
# program is allowed. When working with large data sets, this number may need
# to be increased based on how much memory you wish to allow weka to have.
# Specifying command line arguments will override the defaults shown here.
# Example: '-Xmx512m'
DEFAULT_ARGS='-Xms32m -Xmx256m'
if [ $# -gt 0 ]; then
ARGS="$@"
else
ARGS="$DEFAULT_ARGS"
fi
java -classpath
"${CLASSROOT+CLASSROOT:}/usr/share/java/weka/weka.jar:/usr/share/java/libsvm.jar"
weka.gui.GUIChooser $ARGS

Do not forget to change the MD5SUM of weka.sh in PKGBUILD file :) Modify LibSVM PKGBUILD to:

build() {
cd "$srcdir/$pkgname-$pkgver"
make || return 1
install -D -m755 svm-train $pkgdir/usr/bin/svm-train
install -D -m755 svm-predict $pkgdir/usr/bin/svm-predict
install -D -m755 svm-scale $pkgdir/usr/bin/svm-scale
install -D -m644 java/libsvm.jar $pkgdir/usr/share/java/libsvm.jar
cd "python"
python setup.py build || return 1
python setup.py install --root $pkgdir
}

Then makepgk and install, have fun.
