文件是通用的（三个切片），但它不包含 iOS 上静态库的 (n) ARMv7-s 切片错误，无论如何要绕过？

Question

I upgraded Xcode version and when using external static libraries, I get this message:

ld: file is universal (3 slices) but does not contain a(n) armv7s slice: /file/location for architecture armv7s clang: error: linker command failed with exit code 1 (use -v to see invocation)

Is there any way to bypass this and add support to the library if the developer of the library hasn't updated their library yet?

Answer 1

If you want to remove the support for any architecture, for example, ARMv7-s in your case, use menu Project -> Build Settings -> remove the architecture from "valid architectures".

You can use this as a temporary solution until the library has been updated. You have to remove the architecture from your main project, not from the library.

Alternatively, you can set the flag for your debug configuration's "Build Active Architecture Only" to Yes. Leave the release configuration's "Build Active Architecture Only" to No, just so you'll get a reminder before releasing that you ought to upgrade any third-party libraries you're using.

Answer 2

我只是在目标的构建设置中将“仅构建活动架构”切换为“是”，现在就可以了！

Answer 3

尝试从项目的“有效架构”中删除 armv7s 以针对 iOS 5.1 手机发布此问题

Answer 4

I just posted a fix here that would also apply in this case - basically, you do a hex find-and-replace in your external library to make it think that it's ARMv7s code. You should be able to use lipo to break it into 3 static libraries, duplicate / modify the ARMv7 one, then use lipo again to assemble a new library for all 4 architectures.

Answer 5

Flurry Support for iPhone 5 (ARMv7s) As I mentioned in yesterday's post, Flurry started working on a version of the iOS SDK to support the ARMv7s processor in the new iPhone 5 immediately after the announcement on Wednesday.

I am happy to tell you that the work is done and the SDK is now available on the site.

Answer 6

use menu Project -> Build Settings ->

then remove armv7s from the"valid architectures". If standard has been chosen then delete that and then add armv7.

Answer 7

In case this happens to someone. I built my own library to use with a third party code. While I was building it to deliver, I accidentally left my iPhone 4S plugged in, and so Xcode built my library only for the plugged architecture instead of following the project settings. Remove any plugged in devices and rebuilt the library, link it, and you should be all right.

Hope it helps.

Answer 8

In my case, I was linking to a third-party library that was a bit old (developed for iOS 6, on XCode 5 / iOS 7). Therefore, I had to update the third-party library, do a Clean and Build, and it now builds successfully.
