[英]Why am I seeing the following linker errors when building an iPhone app with Core Plot?
When building an iPhone app that uses the Core Plot framework, I am seeing the following linker errors: 在构建使用Core Plot框架的iPhone应用程序时,我看到以下链接器错误:
ld: warning: ignoring file /Users/taxtmart5/Library/Developer/Xcode/DerivedData/Solagen_Calculator-cwvwcdlnuukfftakggygqoczxyuy/Build/Products/Debug-iphoneos/libCorePlot-CocoaTouch.a, file was built for archive which is not the architecture being linked (armv6)

Under Xcode 3.x, I was able to build this project successfully, but with Xcode 4 it gives the above errors when targeting the device (the Simulator still builds correctly). 在Xcode 3.x下,我能够成功构建这个项目,但是使用Xcode 4时,它会在定位设备时出现上述错误(模拟器仍然正确构建)。
What could be causing these errors, and how can I fix them? 什么可能导致这些错误,我该如何解决它们?
I could solve my problem by 我可以解决我的问题
making change in build settings, 在构建设置中进行更改,
architecture :standard (armv6,armv7) 架构:标准(armv6,armv7)
Build active architecture only : Yes. 仅构建活动架构:是的。
清理您的项目,似乎库之间存在不匹配,因此链接不起作用。
