用MonoTouch本机库绑定链接失败 [英] Linking failure with a MonoTouch native library binding

问题描述

我正在为 Wikitude SDK 创建本机库绑定.

I am creating native library binding for the Wikitude SDK.

MonoTouch应用失败链接:

The MonoTouch app fails linking:

架构armv7的未定义符号:
"std :: __ 1 :: basic_string，std :: __ 1 :: allocator> :: find_last_of(char const *，unsigned long，unsigned long)const"，引用自: WtUnzip :: unzipFileTo(char const *，bool)在WikitudeSDK.a(wtunzip.o)中 ...

Undefined symbols for architecture armv7:
"std::__1::basic_string, std::__1::allocator >::find_last_of(char const*, unsigned long, unsigned long) const", referenced from: WtUnzip::unzipFileTo(char const*, bool)in WikitudeSDK.a(wtunzip.o) ...

我的链接对象:

[assembly: LinkWith ("WikitudeSDK.a", LinkTarget.ArmV7, Frameworks = "CoreVideo Security SystemConfiguration CoreMedia AVFoundation CFNetwork CoreLocation CoreMotion MediaPlayer OpenGLES QuartzCore CoreGraphics", ForceLoad = true, LinkerFlags = "-lsqlite3.0 -ObjC", IsCxx = true)]

我不得不承认我是MonoTouch/IOS领域的新手，因为我想让自己摆脱困境.

I have to admit that I am new to this MonoTouch/IOS world, by I am trying to get my head out of the water.

我应该怎么做才能链接我的应用程序?

What should I do to get my app to link?

推荐答案

我刚刚发现我需要在LinkWith中添加libc ++.我的新LinkWith看起来像这样:

I just figured that I needed to add libc++ in my LinkWith. My new LinkWith looks like this:

[assembly: LinkWith ("WikitudeSDK.a", LinkTarget.ArmV7, Frameworks = "CoreVideo Security SystemConfiguration CoreMedia AVFoundation CFNetwork CoreLocation CoreMotion MediaPlayer OpenGLES QuartzCore CoreGraphics", ForceLoad = true, LinkerFlags = "-lsqlite3.0 -ObjC -lc++", IsCxx = true)]
