Qt 5.x and OS X 10.6

[Ken Cunningham]

Thanks,

I tried 10.7 first, but 5.4.2 would not install due to this message. Ergo moved up the chain to the next machine I had in line.

aha ; of course. Good clue, and should have done that myself naturally... Leads me somewhere...

$ ./analogclock
This application failed to start because it could not find or load the Qt platform plugin "cocoa".

$ otool -L analogclock

Hey - why is it linked against libstdc++ ??? It was installed on 10.11 from a 5.4.2 binary. Would've thought it would link against libc++. 

That might be a dealbreaker...

Later on I'll check the linking for the for QT components... bet I find they are somehow all messed up too.

Agreed. Sigh. I have several machines with EFI32 boot architectures that are stuck in the time warp... unless I can figure out how to do that bootloader hack with them I've seen on the 'net.

Besides 10.6 is just great - Rosetta, fast, etc, etc. And it runs enough to be useful, but I'd like qt5 if it will be available...

Best,
