Re: Qt 4.2.0 Now Available


Message 1 in thread

Hi,

I'm excited about the new Qt 4.2. But I'm wondering when/if this problem 
of supporting Mac OS X version 10.2 will be fixed.

Never?

10.3.9 seems to be the earliest version everyone else is supporting. And
that is all I care about. Why would you need to support earlier (and less
reliable, less secure) versions?

There are valid reasons to support older versions. Perhaps you have a  
customer requirement to support it. Perhaps you simply can't ask your  
customers to buy an upgrade that costs over $100, but you still need  
to be able to deliver new versions of your app?

I just recently dropped support for 10.2 and it wasn't that long ago  
I was supporting 10.1.5.

The reason why they dropped 10.2 has to do with GCC 3 vs. GCC 4. In  
order to support 10.2 or earlier, you would have to be able to  
compile Qt with GCC 3.3 which maybe is possible.

I'm working on 10.3.9 and it still uses gcc-3.3.  gcc-4.* wasn't until 
Tiger.
I hope they aren't dropping 10.3!

I did try a bootstrapped gcc-4.1 once and it didn't work.  You have to 
have Apple's compilers.

OTOH, I used a stock mainline gcc.  Maybe if I downloaded off the Apple 
branch it would work.  hmmm...

There actually several reasons why we dropped 10.2 support, compiler 
really wasn't that much of an issue. The list that springs off the top 
of my head was

* being able to put widgets in the menu (only possible in 10.3 and up).
* Using HITheme throughout instead of maintaining two version of the style
* Using CoreGraphics throughout instead of maintaining two painting 
engines (one of which was deprecated before 4.0 was out)
* Using the newer pasteboard APIs (again only available on 10.3 and up).
* We didn't test on Jaguar as much as we would have liked (no one
develops on it here, for many obvious reasons, not the least of which 
that any new machine manufactured after the 10.3 (2003) release can only 
run 10.3 or better
* There just are not that many new applications out there supporting 10.2

The argument that Apple usually gives for considering to drop support is 
that "if they aren't willing to buy an upgrade, they probably aren't 
willing to spend money on new software". Whether or not this follows in 
a developers case is, of course up to debate.

We discussed it here and we figured that, in order to use newer features 
and assure some sort of parity between OS versions, we needed to cut 
support of 10.2. In general, we're happy with our decision.

Hmm...the last update to 10.2 was in December of 2004.  I would have trouble 
(from a security stand point) supporting anyone using 10.2.  10.3 had a 
security update released on September 29, so seems to be still fully 
supported by Apple.
