[freddy311082]

Hi Guys... tonight I had upgrade my XCode to the new version (version 7), before that everything was perfect, now i got this error:

does anyone know about it ?? because I didn't have this error before upgrade

@freddy311082 Friend, just add to the .PRO file in the Project dir:

QMAKE_MAC_SDK = macosx10.11

QT is trying to use the SDK Version 10.10, but Xcode 7 has the 10.11 version.
Every time you get this error, do "ls /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/" in Terminal and change the QMAKE_MAC_SDK variable accordingly.

nicely done @Leandro, that does it. Cheers!

@Leandro
Well done bro !!! it's work

thanks.... :)

@Leandro said:

ls /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/

Great idea! However, I am now stuck with this error:
:-1: error: Current macosx10.11 SDK version (10.11) is too old. Please upgrade Xcode.

I am surprised because by Xcode is Version 7.0 (7A220)

@Hercule I'm having the same problem when building for iOS. It solves the problem for building a Mac app, but sadly not for building iOS apps. Does anyone have a solution for that?

[wozza]

It seems that when the Xcode update is applied the ios build tools are no longer loaded for creator to use this seems a bigger issue then just setting the SDK version

[wozza]

@wozza Just looking at this and then adding the iphone simulator kit it complains :-1: error: Current macosx10.11 SDK version (10.11) is too old. Please upgrade Xcode. Now if you do ls /Applications/Xcode.app/Contents/Developer/Platforms/ on the terminal you will find multiple sdk kits so how do we then add these kits to the .pro file to support the platform we want to publish too?

[wozza]

@Hercule it seems that if we do QMAKE_MAC_SDK = iphoneos you can then deploy to the iphone

[froncer]

@wozza But if i do QMAKE_MAC_SDK = iphoneos, the old problem with

0: fatal error: 'unistd.h' file not found
#include <unistd.h>

appears again.

@wozza Found the solution by myself by setting only the version for macosx to 10.11:

QMAKE_MAC_SDK.macosx.version = 10.11
