Xcode 4 Final - "armv6 armv7" issue while linking with armv6 libs
提问by cusquinho
Until xcode 4 final (I was using 3.latest and 4 GM for the time it was available) this didn't happen. When I upgraded to xcode 4 final version, I started getting a linking error while trying to link the armv7 version with my non armv7 library (my project is set with the default Standard armv6 armv7 valid architectures):
直到 xcode 4 final（我在可用时使用 3.latest 和 4 GM）这才发生。当我升级到 xcode 4 最终版本时，我在尝试将 armv7 版本与我的非 armv7 库（我的项目设置为默认标准 armv6 armv7 有效架构）链接时开始出现链接错误：
ld: warning: ignoring file ../bin/iOS static/arm/libssl.a, file was built for archive which is not the architecture being linked (armv7)
ld: warning: ignoring file ../bin/iOS static/arm/libcrypto.a, file was built for archive which is not the architecture being linked (armv7)
Undefined symbols for architecture armv7: -- list of symbols --
The armv6 version compiles just fine, but the overall compilation process fails with 77 link errors.
armv6 版本编译得很好，但整个编译过程失败，出现 77 个链接错误。
I understand this is the expected behavior, it wont link towards armv7 with an armv6 lib. The fix is setting my project to armv6 only. My question here is: why was this working in the previous versions of xcode?
我知道这是预期的行为，它不会链接到带有 armv6 库的 armv7。修复是将我的项目设置为仅 armv6。我的问题是：为什么这在以前版本的 xcode 中有效？
If I set to armv6 only, I start to get this warning:
如果我只设置为 armv6，我开始收到此警告：
Check dependencies
[BWARN]warning: all apps should include an armv7 architecture (current ARCHS = "armv6").
I don't like seeing warnings :-) Anybody having similar issues?
我不喜欢看到警告 :-) 有人有类似的问题吗？
Thanks,
谢谢，

I just turned the Build active architecture only to Yes in the Project -> Build Setting -> Architectures tab.
我只是在 Project -> Build Setting -> Architectures 选项卡中将 Build active architecture 设置为 Yes。

In iOS SDK 4.3, it looks like the linker will simply refuse to use a armv6 library in an armv7 binary - this wasn't the case before.
在 iOS SDK 4.3 中，链接器似乎只是拒绝在 armv7 二进制文件中使用 armv6 库 - 以前并非如此。
That's why I had to update the http://code.google.com/p/ios-static-libraries/project to generate both armv6 and armv7 versions of the libraries.
这就是为什么我必须更新http://code.google.com/p/ios-static-libraries/项目以生成库的 armv6 和 armv7 版本。

I have added 3rd Party framework with some demo classes into project but once implemented it successfully I removed those demo classes and since then the error started coming up Error"ld: ........., file is universal but does not contain a(n) armv6 slice for architecture armv6"
我已经将带有一些演示类的 3rd Party 框架添加到项目中，但是一旦成功实施它，我删除了这些演示类，从那时起错误开始出现 错误“ld：……，文件是通用的，但没有包含架构 armv6 的 (n) armv6 切片"
After scratching my head for a whole day I found this solution next morning maybe helpful for fellow iphone buddies coz I know the pain
挠了一整天后，第二天早上我发现这个解决方案可能对 iphone 伙伴有帮助，因为我知道这种痛苦
Targets->"Your Project Target"-> Get Info ->Build Active Architecture only set to YES
Targets->"Your Project Target"-> Get Info -> Build Active Architecture 仅设置为 YES
Thats it..
就是这样..

Had the same problem. But the reason was different I suppose. I was using the library.a file built for simulator and trying to run it on device.. came to know that i need different .a files for simulator and device. I hope this helps someone ;)
有同样的问题。但我想的原因是不同的。我正在使用为模拟器构建的 library.a 文件并尝试在设备上运行它.. 开始知道我需要不同的 .a 文件用于模拟器和设备。我希望这可以帮助别人 ;）

Although I still don't know why this started happening only in the xcode 4 final version, I found that my external libs (ssl and crypto) were compiled against both armv6 and armv7 in the google code project very few days ago:
虽然我仍然不知道为什么只在 xcode 4 最终版本中开始发生这种情况，但我发现我的外部库（ssl 和 crypto）是几天前在谷歌代码项目中针对 armv6 和 armv7 编译的：
http://code.google.com/p/ios-static-libraries/
http://code.google.com/p/ios-static-libraries/
This will fix the issue if you define two different library search path: one for armv6, one for armv7.
如果您定义两个不同的库搜索路径，这将解决该问题：一个用于 armv6，一个用于 armv7。
Thanks,
谢谢，
