MonoTouch Build：ld：未找到架构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，可以在i386 / iOS模拟器上构建和运行。该项目引用了一个本机（Obj-C）库，我使用bamaouch进程转换为MonoTouch DLL，如Xamarin的BindingSample所述：

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/eb640165f0485ff59b2f80e73ccff382bf4f2083/BindingSample/src/binding

所以我的makefile构建了所有三种架构（i386，armv6和armv7），然后将三个输出组合到一个'Universal'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 ，实际上，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.

然而，当我在实际的iOS设备上进行部署时，我会收到以下错误：

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：本地库依赖于AddressBook框架，我忘了把它包含在AssemblyInfo.cs中API定义项目：

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")]
