Description

Hello !

With the recent release of the iPhone 3GS along with the iPhone OS 3.0, these improvements to nuiE should be considered,
as they are required for any submission of 3.0-compatible applications:

  • Base SDK should be set to iPhone Device 3.0 (Currently 2.2)
  • Default compiler should be set to GCC-4.2 (Currently 4.0)
  • Base architecture should be set to Optimized, having armv6 and armv7 targets. (Currently Standard / armv6)
    Apple just introduced iPhone Universal Binairies for this purpose. Build for current target only shall be set only
    for the debug target.

Currently any XCode projects having mixed armv6/armv7 can't link due to the nuiE dependency. ('lipo' can't link
2 binary objects of the same architecture).

I can provide a patch accordingly.

Cheers,
Mathieu Garcia

Note: Base archivecture is NOT a requirement for fully 3.0 compatible, but would be highly appreciated.

I think the best option would be to create two diferent targets in nuiE:
- one for 2.x phones that is not UB
- one for 3.0 UB

In the same idea I would love to see nuiE merged in the main nui.xcodeproj project file for Mac.
I don't have much time to work on that right now but you seem to understand the issues quite well so would you like to do it? ;-)

Hello !

Yes, the best solution would be to have 2 targets in nuiE.
I can modify my current patch and send it back to you.

The inclusion of nuiE targets in nui targets is also a great idea, however I'd prefer to begin
with the nuiE-only patch, for now.

Thank you,
Cheers !

Hi,

I have the patch ready, tested it against various projects that required 3.0 UB nuiE dependency.
I also ensured the initial targets (2.2-ish) were still working.

Further testing might help ensuring this patch is 100% safe to apply.

Cheers !
