Question

我一直在尝试根据Google在http://www.webrtc.org/native-code/ios（以及相关链接）上的指示构建适用于iOS的webrtc。虽然我记得在过去我已经能够建立它的类似步骤已经不再是这样了。

以下是我所做的步骤：

下载先决条件：

$ git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

$ export PATH =`pwd` / depot_tools：“$ PATH”
下载回购：

$ export GYP_DEFINES =“OS = ios”

$ fetch webrtc_ios
准备构建：

$ cd webrtc / src

$ export GYP_DEFINES =“build_with_libjingle = 1 build_with_chromium = 0 libjingle_objc = 1”

$ export GYP_DEFINES =“$ GYP_DEFINES OS = ios target_arch = armv7”

$ export GYP_GENERATOR_FLAGS =“output_dir = out_ios”

$ export GYP_CROSSCOMPILE = 1

$ gclient runhooks
构建

$ ninja -C out_ios / Debug-iphoneos AppRTCDemo

一切正常，直到用/ bin / sh失败的最后一个命令：/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc：没有这样的文件或目录：

ninja: Entering directory `out_ios/Debug-iphoneos'

出于某种原因，忍者认为我们正在为模拟器建造，加上即使我们这样做也不是获得gcc的正确途径。请注意，我的系统已安装XCode 7.

任何可能出错的想法或我如何解决这个问题？

祝你好运，安东尼

一年前，我还想用谷歌的指示建立图书馆，但我无法做到。发生了很多错误，我最终搜索了一些构建脚本。最后我找到了this script。进行以下步骤，您将成功构建它：

安装命令行工具，但在终端中粘贴此命令：xcode-select --install
克隆脚本：git clone https://github.com/lunastorm/webrtc-ios.git
在终端中输入git repository并使用以下命令运行脚本：make -j4其中j4标记CPU核心数（如果我错了，请纠正我）。这可能需要一段时间，所以准备一杯咖啡
构建将首次失败，但不要担心，只需删除脚本下载的文件夹。我会在编辑中写下哪些
找到适用于构建iOS应用的代码签名标识。在终端中输入security find-identity。在Valid identities only
打开全局配置文件src / build / common.gypi并搜索文本“CODE_SIGN_IDENTITY”。将‘CODE_SIGN_IDENTITY[sdk=iphoneos*]‘: ‘iPhone Developer’替换为您的开发者信息，例如‘CODE_SIGN_IDENTITY[sdk=iphoneos*]‘: ‘iPhone Developer: Josip Bernat (2V3DKW6SDC)’
使用make -j4再次运行脚本，希望它能为您构建WebRTC.framework
