iOS WeMo SDK架构问题

Question

我正在尝试使用Belkin构建一个控制WeMo Switch的应用程序。他们发布了自己的SDK来控制他们的产品，我已将它们包含在我的图书馆搜索路径和我的链接库和框架工作区中。

首先我尝试编译所有架构（包括arm64）并获得以下Mach-O链接器错误

ld: warning: ignoring file /Users/khwaab/src/enimai/iOS/House Control/-
iphoneos/BelkinSDKLibrary.a, missing required architecture arm64 in file
/Users/khwaab/src/enimai/iOS/House Control/-iphoneos/BelkinSDKLibrary.a (3 slices)

iphoneos/Reachability.a, missing required architecture arm64 in file 
/Users/khwaab/src/enimai/iOS/House Control/-iphoneos/Reachability.a (3 slices)

Undefined symbols for architecture arm64:

"_OBJC_CLASS_$_WeMoDiscoveryManager", referenced from:

  objc-class-ref in LightControlViewController.o

ld: symbol(s) not found for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

接下来我尝试禁用arm64，假设库不是64位（如果我错了，请纠正我）

不知道从哪里开始，我怀疑这个库是过时的而不是armv7 / 7s（它也不会在模拟器下的i386中构建）但是如果有人对这个或任何想法有任何好运，那么任何东西非常感谢。

Answer 1

这是我从这个问题中恢复的解决方案。

• 将文件夹-iphonesos中提供的库包含在项目中。

• 将以下框架添加到Project。

  1. libxml2.dylib
  2. CFNetwork.framework
  3. MobileCoreServices.framework
  4. Security.framework
  5. SystemConfiguration.framework
  

• 然后转到您的构建设置＆amp;寻找架构。

• 点击其他内容添加新值...＆amp;添加此$(ARCHS_STANDARD_32_BIT)

• 如果您也可以选择，$(ARCHS_STANDARD)表示Standard architectures (armv7, armv7s)

• 构建项目，您将摆脱所有链接器错误。

Answer 2

即使它还没有使用@ Balram的回答，这也是有帮助的。 你必须在＆＃34;其他链接器标志＆＃34;中添加-lxml2。目标构建设置中“链接”部分下的属性。 这对我有用

Answer 3

使用此部分显示错误，尽管有armv7或$（ARCHS_STANDARD_32_BIT）解决方案？
