(Solved) Help with hybrid Slackbuild script.

Post by globetrotterdk » 5. Mar 2016, 22:54

I am hoping that some one on the forum is interested in giving me a hand with the following Slackbuild. I am trying to go for the salient points (seen from my perspective) in both the existing Slackbuild script for VueScan, as well as a Slacky build script. The first issue was of course updating to the latest file name. Secondly, I want to install the program in /usr/bin. Thirdly, install a vuescan.png file, and lastly ensure that a menu item appears in Salix64 14.1 MATE application menu. (The scrip items are listed above as per priority and not according to position in the script.)

Did I combine the scripts successfully? If not, what do I need to change?

Code: Select all

#!/bin/sh

# Heavily based on the Slackware 14.1 SlackBuild as well as an Slacky Slackbuild.
# Packager GlobetrotterDK

PRGNAM=vuescan
VERSION=${VERSION:-9.4.47}
BUILD=${BUILD:-1}
TAG=${TAG:-_SBo}

# and choose source file accordingly
if [ -z "$ARCH" ]; then
  case "$( uname -m )" in
    i?86)
	ARCH=i486
	SOURCEFILE=vuex3295.tgz ;;
    x86_64)
	ARCH=x86_64
	SOURCEFILE=vuex6495.tgz ;;
    # Other archs are unsupported:
       *) echo "ARCH $( uname -m ) is unsupported."; exit 1 ;;
  esac
fi

CWD=$(pwd)
TMP=${TMP:-/tmp/SBo}
PKG=$TMP/package-$PRGNAM
OUTPUT=${OUTPUT:-/tmp}

set -e 

rm -rf $PKG
mkdir -p $TMP $PKG $OUTPUT
cd $TMP
rm -rf $PRGNAM-$VERSION
mkdir -p $PRGNAM-$VERSION
cd $PRGNAM-$VERSION
tar xvf $CWD/$SOURCEFILE
chown -R root:root .
find -L . \
 \( -perm 777 -o -perm 775 -o -perm 750 -o -perm 711 -o -perm 555 -o -perm 511 \) \
 -exec chmod 755 {} \; -o \
 \( -perm 666 -o -perm 664 -o -perm 600 -o -perm 444 -o -perm 440 -o -perm 400 \) \
 -exec chmod 644 {} \;

Have you tried running it? If it fails, please post the output.

Thanks for the quick reply mimosa. Here is the output:

Code: Select all

$ ./vuescan.SlackBuild
bash: ./vuescan.SlackBuild: Permission denied
$ sudo ./vuescan.SlackBuild
sudo: ./vuescan.SlackBuild: command not found
Unfortunately I didn't get very far. I assume this has something to do with "sudo"?

$ chmod +x vuescan.Slackbuild 
$ sudo ./vuescan.Slackbuild 
I am curious as to why you are doing this.

Without having looked at all closely at this, I suspect moving the main executable to /usr/bin won't work, otherwise the sources you're drawing on would have done it already. For whatever reason, all the files must need to be together somewhere else.

You could probably make a symlink from /usr/bin/whatever to the appropriate file in /opt (or other location of your choice); or else add the location to your $PATH.

Thanks. I just picked up on this myself. The original Slackbuild puts the executable in /opt and then writes a script that goes into /usr/bin. In reality (believe it or not) I am just trying to make things simpler and make sure that the executable will show up in the MATE application menu -> Graphics.

After sorting out the cmod, this is what I got:

Code: Select all

]$ chmod +x vuescan.SlackBuild
$ sudo ./vuescan.SlackBuild
VueScan/
VueScan/vuescan.ds
VueScan/vuescan.svg
VueScan/vuescan
VueScan/vuescan.8ba
chmod: cannot access ‘/tmp/SBo/package-vuescan/usr/lib/VueScan/vuescan’: No such file or directory
The Slacky version of the script does it like this, which seems simpler to me:

Code: Select all

# Install the executable file.
mkdir -p $PKG/usr/bin
cat <<EOF >$PKG/usr/bin/vuescan
#!/bin/sh
exec /usr/lib/VueScan/vuescan
EOF
chmod +x $PKG/usr/bin/vuescan
chmod +x $PKG/usr/lib/VueScan/vuescan


mkdir -p $PKG/usr/share/{applications,pixmaps}
cat $CWD/vuescan.png > $PKG/usr/share/pixmaps/vuescan.png

cat << EOF > $PKG/usr/share/applications/vuescan.desktop

cat $CWD/$NAME.SlackBuild > $PKG/usr/doc/$NAME-$VERSION/SlackBuild/$NAME.SlackBuild

	echo "if [ -x /usr/bin/update-desktop-database ]; then
  /usr/bin/update-desktop-database &> /dev/null
fi" >> $PKG/install/doinst.sh
	echo "" >> $PKG/install/doinst.sh
	echo "if [ -x /usr/bin/gtk-update-icon-cache ]; then
  /usr/bin/gtk-update-icon-cache  -f -q /usr/share/icons/hicolor &> /dev/null
fi" >> $PKG/install/doinst.sh
	echo "" >> $PKG/install/doinst.sh
The executable can be run from the desktop, so there is no specific place that it resides. I am just trying to get things stowed away in their proper places the Slackware way, and make sure that the executable shows up under the proper menu sub-heading.

I agreed that there should be a desktop file so that you can launch from a menu, but the SBo slackbuild doesn't created it. However i don't think you need to move the binaries to /usr/bin.

Just let it installed the script and your desktop file that you are creating will work with it.

Actually the easiest thing to do is to create the desktop file, save it to /usr/shar/applications and install vuescan using the Slackbuild unchanged. Then in the future you can easily update vuescan using spi or slapt-src ( although it does have an issue with changing checksums so you still may need to run the Slackbuild manually)

OK. I created the vuescan.desktop file manually and copied the included the .svg image file to the correct place. I then downloaded the SBo Slackbuild script and only modified the file name to fit the downloaded file. I ran the script and installed the package. Everything seems to work fine, so I am happy despite not having learned anything more about the formulation and workings of Slackbuild scripts.

You do know that unless you pay and register vuescan, it puts watermarks on all your scanned documents.
