命令行调试构建项目架构 i386 的未定义符号

Question

运行xcodebuild -target szapp 返回：

CONFIGURATION_BUILD_DIR=$/Users/szmall/Documents/new12/trunk/head/ShiZu -configuration Debug build -sdk iphonesimulator9.2 ONLY_ACTIVE_ARCH=NO VALID_ARCHS='arm64 armv7s armv7 i386'
build my project have this error:
Undefined symbols for architecture i386:

      objc-class-ref in libSocialQQ.a(UMSocialQQHandler.o)

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

但 libSocialQQ.a 存在于 Link Binary With Libraries。

并且使用 xcode 运行我的项目可以构建成功。请帮帮我，谢谢！

从 Target 的 Build Settings -> Architectures -> Valid Architectures 中移除 i386，无需指定。但是，如果您的库不包含 i386 的代码 - 尝试在旧模拟器上运行它会遇到问题。

顺便说一句，您可以使用命令lipo -info libSocialQQ.a 检查支持的架构。
