xcode 5.1 - Undefined symbols for architecture x86_64 (zbar)
提问by Atanu Mondal
I have updated my x code version from 5.0 to 5.1
I have used ZBarSDK in my project for scan bar code. In simulator 'iPhone Retina (3.5-inch)' and 'iPhone Retina(4-inch)', it is working fine. But when i want to build with simulator 'iPhone Retina (4-inch 64-bit)', it is giving the following error.
我已经将我的 x 代码版本从 5.0 更新到 5.1
我在我的项目中使用了 ZBarSDK 来扫描条形码。在模拟器“iPhone Retina（3.5 英寸）”和“iPhone Retina（4 英寸）”中，它运行良好。但是，当我想使用模拟器“iPhone Retina（4 英寸 64 位）”进行构建时，出现以下错误。
ld: warning: ignoring file /Users/sayan/Desktop/ProjectAtanu/Omlis/Custom Classes/ZBarSDK/libzbar.a, missing required architecture x86_64 in file /Users/sayan/Desktop/ProjectAtanu/Omlis/Custom Classes/ZBarSDK/libzbar.a (3 slices)

Any help much appreciated!
非常感谢任何帮助！

USING PODS
使用豆荚
pod 'ZBarSDK'
OR
或者
Recompile ZBar for iphone 5. You can download recompiled ZBAR from hereto skip the following
Recompile ZBar for iphone 5. 你可以从这里下载重新编译的ZBAR跳过下面的
Steps
脚步
Download the source code (you must have Mercurialfor mac):
Open Terminal and run following commands
a. hg clone http://zbar.hg.sourceforge.net:8000/hgroot/zbar/zbar
b. cd zbar
c. hg checkout iPhoneSDK-1.3.1
d. open iphone/zbar.xcodeproj
In the xcode project edit the "libzbar" scheme and select Release in Build configuration
Go to Build Settings set following Architectures
a. Architectures- >Standard architectures(armv7,armv72,arm64)
b. Valid Architectures-> arm64,armv7 armv7s
Compile libzbar for deviceAND for simulator, here the configuration:
Find the compiled libzbar.a and go in the folder using Teminal.app,
In My Case : /Users/kappe/Library/Developer/Xcode/DerivedData/zbar-gyozyrpbqzvslmfoadhqkwskcesd/Build/Products
In this folder you you should have two sub folder Release-iphoneos and Release-iphonesimulator
using xcode command line tools build your universal lib:
lipo -create Release-iphoneos/libzbar.a Release-iphonesimulator/libzbar.a -o libzbar.a
Now you can use the libzbar.a created, both in device and simulator.
下载源代码（你必须有Mac 版Mercurial）：
打开终端并运行以下命令
一种。汞克隆http://zbar.hg.sourceforge.net:8000/hgroot/zbar/zbar
湾 cd zbar
C。汞结帐 iPhoneSDK-1.3.1
d. 打开 iphone/zbar.xcodeproj
在 xcode 项目中编辑“libzbar”方案并在构建配置中选择发布
转到遵循架构设置的构建设置
一种。架构- >标准架构(armv7,armv72,arm64)
湾 有效架构-> arm64,armv7 armv7s
为设备和模拟器编译 libzbar ，这里是配置：
找到编译好的 libzbar.a 并使用 Teminal.app 进入文件夹，
在我的情况下：/Users/kappe/Library/Developer/Xcode/DerivedData/zbar-gyozyrpbqzvslmfoadhqkwskcesd/Build/Products
在这个文件夹中你应该有两个子文件夹 Release-iphoneos 和 Release-iphonesimulator
使用 xcode 命令行工具构建您的通用库：
lipo -create Release-iphoneos/libzbar.a Release-iphonesimulator/libzbar.a -o libzbar.a
现在您可以在设备和模拟器中使用创建的 libzbar.a。

This implies the library is not supported/built for the new archtitecture.
这意味着该库不支持/为新架构构建。
For zBar this answerhas link to tutorial where you can download the source and just update the lib to new architecture.
对于 zBar，此答案包含指向教程的链接，您可以在其中下载源代码并将库更新为新架构。
Generally for a third party service. they will release new lib with the architecture added so make sure to check out their site for updated SDK.
一般用于第三方服务。他们将发布添加了架构的新库，因此请务必查看他们的站点以获取更新的 SDK。

Put in you Build Settings under "Other Librarian Flags" and "Other Linker Flags": $(OTHER_LDFLAGS)
在“其他图书馆员标志”和“其他链接器标志”下放入构建设置：$(OTHER_LDFLAGS)
