Thread-topic: One Package, 2 platforms

Something like this should work:

<?xml version="1.0" encoding="utf-8"?>
<installer-script minSpecVersion="1.000000"
authoringTool="com.apple.PackageMaker" authoringToolVersion="3.0.1"
authoringToolBuild="172">
	<title>Title</title>
	<options customize="allow" allow-external-scripts="no"/>
	<script type="text/javascript">

	function check_osver(osver)
	{
		var myVer = System.version['ProductVersion'];
		if(check_version(myVer, osver))
			return false;
		else
			return true;
	}

	function is_higher(ver1, ver2)
	{
		ver1 = ver1.split(".");
		ver2 = ver2.split(".");

		for(var i=0;i<2;i++)
		{
			if(parseInt(ver1[i]) > parseInt(ver2[i]))
			{
				return true;
			}
			else if(parseInt(ver1[i]) <
parseInt(ver2[i]))
			{
				return false;
			}
		}
		return false;
	}

	</script>

	<choices-outline>
		<line choice="choice0" />
		<line choice="choice1" />
	</choices-outline>
	<choice id="choice0" title="Package 10.5" description="This
package is for 10.5 only." start_visible="check_osver('10.5')"
start_selected="check_osver('10.5')">
		<pkg-ref id="com.smarttech.notebook10" />
	</choice>
	<choice id="choice1" title="Package 10.4" description="This
package is for 10.4 only." start_visible="check_osver('10.4')"
start_selected="check_osver('10.4')">
		<pkg-ref id="com.smarttech.notebookTools" />
	</choice>
	<pkg-ref id="com.test.pkg" installKBytes="126656"
version="10.0.246.1"
auth="Root">file:./Contents/Packages/10.5.pkg</pkg-ref>
	<pkg-ref id="com.test.pkg" installKBytes="40576"

</installer-script>

I have not tested this though but should get you moving in the right
direction (this is a distribution.dist file.)

Hi Pradeep,

Awesome information, do you have an example on meta packages? I dont
quite know what I should about them.

Thanks,

-Jason

Hi Jason
You can install the files in a temporary location and then move them
to the
OS specific location using postinstall or postupgrade scripts. Of
course in
this case the BOM will not contain the location where the files
really end
up, but if that's not a problem then the above mentioned method
should work.
Another alternative is to create 2 pkgs and then wrap them into a meta
package and have the OS based version check in the InstallationCheck
script
that will block the installation of one pkg or the other depending
on the OS
the mpkg is installed on.

Hi All,
I want to create a package installer that works on both Tiger and
Leopard. My issue is that 10.4 and 10.5 keep system Python files in a
different location.
Is it possible to create an installer that can put files in a
different location depending upon platform version? I have tried
and I
am not seeing what I can do.
Thoughts?
Thanks,
-Jason
