RE: How to skip the installation when install a lower version. (PackageMaker3.02)

(PackageMaker3.02) Hi David, The package version I mean is the "Package Version:" string in "Configuration" tab of the Package's "Contents". I suppose this version info should effect in the way of preventing down-grade. (But, it doesn't work. I searched a.receiptdb, the version sting was recorded, but it seems that the installer won't compare it.)
This script should be put into the preinstall section of your installer or so. I think I can try this method by installing a file which stores the version info. But what can I do in the bash script to stop/skip the process of installation if I find that I am installing a lower version?
Best Regards, Kevin Gu

hi Kevin,
there is a file called "My.pkg/Contents/Resources/package_version <cid:part1.07070707.01050206@Native-Instruments.de>" contained in the package. I dont know in which way it differs from the version number of the app, but maybe it helps...

Hi David,
Thank you very much for your reply.
What I really want is to compare the version of install packages. (Not the version of my application, because I install not only bundle but also other related files.)
Anyway, I have made a small test to try the script and my test result is below: /private/tmp/scripts.IXRi/./preinstall[688] Version_Now(1.49.001) < Version_Old(1.51.001) That means I do have installed a low version and replace the higher one.
So, do you have the second suggestion...?
Best Regards, Kevin Gu

Hi Kevin,
my fist suggestion would be to write a little bash script that compares two version numbers. This script should be put into the preinstall section of your installer or so.
The script should look something like this (it is only example code!!!):
#!/bin/sh #Script is checking if VERSION_B is higher, lower or equal to Version_A
#This is how my Version number looks like: VERSION_A="0.5.0.002"
#Read it out the plist VERSION_B=`defaults read "/Applications/my.app/Contents/Info" "CFBundleShortVersionString"`
echo "echo1:" $VERSION_B echo "echo2:" $VERSION_A
#Reading String VERSION_A to array and writing it to Val_A without "."
V1[1]=${VERSION_A:0:1} echo ${V1[1]} V1[2]=${VERSION_A:2:1} echo ${V1[2]} V1[3]=${VERSION_A:4:1} echo ${V1[3]} V1[4]=${VERSION_A:6:3} echo ${V1[4]}
#put serial back together without dots Val_A=${V1[1]}${V1[2]}${V1[3]}${V1[4]} echo $Val_A
#Reading String VERSION_A to array and writing it to Val_B without "." V2[1]=${VERSION_B:0:1} echo ${V2[1]} V2[2]=${VERSION_B:2:1} echo ${V2[2]} V2[3]=${VERSION_B:4:1} echo ${V2[3]} V2[4]=${VERSION_B:6:3} echo ${V2[4]}
#put serial back together without dots Val_B=${V2[1]}${V2[2]}${V2[3]}${V2[4]} echo $Val_B
#-Comparing here: #-instead of echo there should be something like return 0 in case of success or anything higher starting at 64 #will stop the isntallation.
if [ $Val_A -gt $Val_B ] then echo "V1 > V2" fi
if [ $Val_A -lt $Val_B ] then echo "V1 < V2" fi
if [ $Val_A = $Val_B ] then echo "V1 = V2" fi
Greetings
David

Hi all,
I know this might be a very simple question, but I tried and failed many times
and have to write this mail.
What I want is very simple: 1. Installation runs when install an initial version or install a higher
version.
2. Installation skips when install an lower version.
I have tried the "Package Version", but it doesn't work. I use PackageMaker 3.02 on Leopard.
Any help will be highly appreciated. Thanks in advance.
Best Regards, Kevin
