MonoTouch 版本:ld:找不到架构 armv7 的符号 [英] MonoTouch Build: ld: symbol(s) not found for architecture armv7

问题描述

我有一个 MonoTouch 项目，它在 i386/iOS 模拟器上构建和运行良好.该项目引用了本机 (Obj-C) 库，我使用 Xamarin 的 BindingSample 中所述的 btouch 进​​程将其转换为 MonoTouch DLL:

I have a MonoTouch project which builds and runs fine on i386/iOS Simulator. The project references a native (Obj-C) library, which I converted to a MonoTouch DLL by using the btouch process as described in Xamarin's BindingSample:

https://github.com/xamarin/monotouch-samples/tree/eb60165f0485ff59b2f80e73ccff382bf4f2083/BindingSample/src/binding">https://github.com/xamarin/monotouch-samples/tree/eb60165f0485ff59b2f80e73ccff382/BindingSample/src/binding

所以我的 makefile 构建了所有三个架构(i386、armv6 和 armv7)，然后将三个输出组合到一个通用"库中，最后使用 btouch 生成一个 MonoTouch DLL.

So my makefile builds all three architectures (i386, armv6 and armv7), then combines the three outputs to one 'Universal' library, and finally uses btouch to generate a MonoTouch DLL.

为了确保我的通用库包含所有三种架构，我检查了 lipo -info，确实，它包含 i386、armv6 和 armv7.

To be sure that my universal library contains all three architectures, I checked with lipo -info, and indeed, it contains i386, armv6 and armv7.

但是，当我在实际的 iOS 设备上构建部署时，我收到以下错误:

However, when I'm building for deployment on an actual iOS device, I get the following errors:

mtouch exited with code 1

我做错了什么?

推荐答案

发现问题:原生库依赖AddressBook框架，忘记在API定义项目的AssemblyInfo.cs中包含:

found the problem: the native library depended on the AddressBook framework, and I forgot to include it in the AssemblyInfo.cs of the API definition project:

[assembly: LinkWith ("libContactsTokenFieldViewUniversal.a", LinkTarget.Simulator | LinkTarget.ArmV6 | LinkTarget.ArmV7, ForceLoad = true, Frameworks="AddressBook Foundation")]
