Build iPhone target failed after updating to Xcode 8

[KenHuang0917]

Operating system or device - Godot version:
macOS Sierra, Godot 2.1 stable, Xcode 8

Issue description (what happened, and what was expected):
After updating to Xcode 8, build iPhone target failed with the following message:

clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of iOS 7
ld: library not found for -lcrt1.3.1.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)
scons: *** [bin/godot.iphone.opt.arm] Error 1
scons: building terminated because of errors.

With Xcode 7, everything is just fine.
Going back to Xcode 7 by Time Machine, build OK as before!

Steps to reproduce:
Terminal build instruction is as the following:
Scons platform=iphone tools=no bits=64 target=release

Thanks for helping!

As mentioned in #6715, increasing the minimum required version to 7.0 seemed to fix the issue for @ret80.

Thanks for helping but could you please show me how to "increase the minimum required version to 7.0"?

[ret80]

path: godot/platform/iphone/detect.py
replace with "-miphoneos-version-min=5.1.1" to "-miphoneos-version-min=7.0"
del "-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk"

[ret80]

There is a suspicion that if you remove the "-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk" is to increase the version of the possible and not necessary. In the evening, I check this nuance.

[KenHuang0917]

Thank you! It worked!

[akien-mga]

It worked for you, but not for all other Xcode 8 users ;)

Any solution?

Undefined symbols for architecture armv7:

The same error with XCode 8.2.1 (OSX El Capitan 10.11.6) Godot 2.1.2:

clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of iOS 7
ld: library not found for -lcrt1.3.1.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)
scons: *** [bin/godot.iphone.opt.arm] Error 1
scons: building terminated because of errors.

scons p=iphone tools=no bits=64 target release arch=arm64 -> Builded OK
scons p=iphone tools=no bits=32 target release arch=arm -> With error -lcrt1.3.1.o

Resolved by:
edit "godot/platform/iphone/detect.py" and replace ALL match -miphoneos-version-min=5.1.1
to -miphoneos-version-min=7.0 as @ret80 commented.

This fixed in "master" branch

@tulsidaskhatri How is your problem? You manage to solve it?
If not yet. I tell you that I had same problem and fixed it.
Problem is because a dependency is missing.
You need to add "-framework", "CFNetwork" in LINKFLAGS array in config.py.
Whatsmore, below is my full deps list:

env.Append(LINKFLAGS=[
            "-ObjC",
            "-framework", "CFNetwork",
            "-framework", "SystemConfiguration",
            "-framework", "EventKit",
            "-framework", "EventKitUI",
            "-framework", "AdSupport",
            "-framework", "AudioToolbox",
            "-framework", "AVFoundation",
            "-framework", "MobileCoreServices",
            "-framework", "CoreGraphics",
            "-framework", "CoreMedia",
            "-framework", "CoreMotion",
            "-framework", "CoreTelephony",
            "-framework", "CoreVideo",
            "-framework", "Foundation",
            "-framework", "GLKit",
            "-framework", "JavaScriptCore",
            "-framework", "MediaPlayer",
            "-framework", "MessageUI",
            "-framework", "Messages",
            "-framework", "MobileCoreServices",
            "-framework", "OpenGLES",
            "-framework", "SafariServices",
            "-framework", "StoreKit",
            "-framework", "SystemConfiguration",
            "-framework", "UIKit",
            "-framework", "WebKit",
            "-framework", "GoogleMobileAds"])

PS Sorry for "digging" in old closed thread.

@BastiaanOlij does this still fail to you?

[tulsidaskhatri]

@lukaszbulzacki Thanks for your help, I solved this problem too, but now I hardly remember anything about the project or this thread. Thanks 👍

[BastiaanOlij]

@reduz compiling on xcode 8 and 9 beta works fine. From memory, we moved the minimum build for 2.1.x to iOS 7 and for 3.0 to iOS 9.

Do need to check the simulator build one of these days.

I'm not sure about the other issues mentioned here but I think this can be closed.
