 Posted: Thu Feb 15, 2007 11:53 am Post subject: tovid-0.30 on Gentoo |
 |
|
As i'm the maintainer of the gentoo-ebuild of tovid i'm trying hard to keep the newest version of tovid in portage. I never had any problems with tovid before but with tovid-0.30 a big bug makes running tovid on gentoo alot harder.
the problem is related to this part of tovid-init:
| Code: |
INSTALLED_TOVIDS=$(type -a tovid 2>>/dev/null | awk '{print $NF}' | tr '\n' ' ')
NUM_INSTALLED=0
# Only count non-links
for tovid in $INSTALLED_TOVIDS; do
if ! test -L $tovid; then
let "NUM_INSTALLED=NUM_INSTALLED+1"
fi
done
# Exit when there is more than one tovid installed
if test $NUM_INSTALLED -ne 1; then
echo "Found $NUM_INSTALLED installations of tovid on your system!"
echo "I won't run until there is only one of me :)"
echo "Installed versions:"
for version in $INSTALLED_TOVIDS; do
echo " $version"
done
echo "Exiting..."
exit 1
fi

You see on Gentoo /usr/X11R6 is a symlink to /usr and thus it finds the tovid-skript twice (one time in /usr/bin and the second time in /usr/X11R6/bin)
here's the exact output when i try to execute tovid:
| Code: | tovid
Found 2 installations of tovid on your system!
I won't run until there is only one of me :)
Installed versions:
/usr/bin/tovid
/usr/X11R6/bin/tovid
Exiting...

I get your intentions of the above code (prevent troubles with different installed versions of tovid) but it's not working in the case of Gentoo. As possible solution I would suggest that you not only check for the existence of files with the name tovid but you also check for the version-number of the files.
As a workaround i hacked up the ebuild to install the executables in /usr/local/bin and patch the configure-file to install the python-scripts into /usr. I know it's not a beautiful solution but as i'm not that good with bash-scripting that was the only real solution i could think of that wasn't too time-consuming. |

Thanks for posting about this--I never encountered this problem on my Gentoo box, because (as I just discovered) /usr/X11R6/bin is not on my $PATH. Checking version number is a good idea; I'll fix it so it only complains if conflicting versions are installed.
Meanwhile, a workaround for other Gentoo users who have this problem is to take /usr/X11R6/bin out of your $PATH.

There's a fix in svn now. Can't wait till distros take the Mobius strip out of their PATHs :-)
| Code: | INSTALLED_TOVIDS=$(type -a tovid 2>>/dev/null | awk '{print $NF}' | tr '\n' ' ')
NUM_INSTALLED=0
INSTALLED_VERS=""
INSTALLED_PREFS=""
# Only count tovids that are different versions
for tovid in $INSTALLED_TOVIDS; do
tovid_PREFIX=$(dirname $tovid)
tovid_VERSION=$(grep TOVID_VERSION $tovid_PREFIX/tovid-init | \
awk -F '"' '{print $2}')
INSTALLED_VERS="$INSTALLED_VERS $tovid_VERSION"
done
UNIQ_TOVIDS="$(echo $INSTALLED_VERS | tr ' ' '\n' | uniq)"
NUM_INSTALLED="$(echo $INSTALLED_VERS | tr ' ' '\n' | uniq | wc -l)"
# Exit when there is more than one tovid installed
if test $NUM_INSTALLED -ne 1; then
echo "Found $NUM_INSTALLED versions of tovid on your system!"
echo "I won't run until there is only one of me :)"
echo "Installed versions:"
i=1
while test $i -le $(echo "$INSTALLED_TOVIDS" | awk '{print NF}'); do
tovid_ver=$(echo $INSTALLED_VERS | awk '{print $'$i'}')
tovid_path=$(echo $INSTALLED_TOVIDS | awk '{print $'$i'}')
printf " %s (%s)\n" $tovid_ver $tovid_path
let "i=i+1"
done
echo "Exiting..."
exit 1
fi |
