Linker warnings with XCode 5.1 beta

[koenvanderdrift]

I'm getting these warnings with the latest beta (don't remember if they were there before):

warning: /Applications/Xcode51-Beta5.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: -dynamic not specified, -all_load invalid /Applications/Xcode51-Beta5.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: -dynamic not specified the following flags are invalid: -ObjC /Applications/Xcode51-Beta5.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file: ../Build/Intermediates/CorePlot-CocoaTouch.build/Debug-iphonesimulator/CorePlot-CocoaTouch.build/Objects-normal/i386/CPTDefinitions.o has no symbols /Applications/Xcode51-Beta5.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file: ../Build/Intermediates/CorePlot-CocoaTouch.build/Debug-iphonesimulator/CorePlot-CocoaTouch.build/Objects-normal/i386/CPTPlatformSpecificDefines.o has no symbols

It sounds like the linker changed. I don't have Xcode 5.1 yet to test with. Does the error occur only on the 2.0 branch or on the master branch, too?

XCode 5.1 just came out.

It showed up in Software Update right after I posted this. :-) I'll look at this as soon as I can.

Note: it doesn't affect already build packages. I can compile my app just fine with the framework I previously built.

The new Softwarebuild require 64bit by default and Core Plot doesn't have the 64-bit architecture in it. So, at the minimum, CorePlot needs to be compiled for 64bit support included as the standard architeure included with XCODE 5.1. This is now and Urgent priority issue as all apps are going to face this issue. A typical error message now is
Undefined symbols for architecture arm64:
"OBJC_CLASS$_CPTScatterPlot", referenced from:

Sorry about that - I was going to close the comment window, not the topic. That button is rather confusing.

Setting ONLY_ACTIVE_ARCH = NO; will allow all architectures to build with errors. However, the warning above still appears.

I'm going to do one more release with Xcode 5 and the old project settings for people who are supporting older systems. After that, I'll merge the release-2.0 branch into master so we only have one branch to maintain. This will eliminate the Xcode 5.1 errors from garbage collection being no longer supported. I will also add the 64-bit architecture to the iOS project settings and update the linker flags to eliminate the warning reported in this issue. I hope to have this all done by the coming weekend.

Great news, thank you!

[koenvanderdrift]

Still getting a bunch of errors when ONLY_ACTIVE_ARCH = YES; in the debug build settings. Setting it to NO solves that.

[eskroch]

I get clean debug builds. What errors are you seeing?

[koenvanderdrift]

I'm seeing lots of these:

[eskroch]

Do you see this error with any of the example apps? I've done clean builds of the Plot Gallery on its own and within the CorePlotExamples workspace and it builds fine both ways.

[koenvanderdrift]

No problems there. And I found why it happened in my project, I had ONLY_ACTIVE_ARCH = NO; in my own project as well. Once I set that back to YES all errors were gone.

[eskroch]

Good news. Thanks for tracking this down.
