讓自己的vs工程能夠使用webrtc庫

總述

1、采用的代碼是 /69   2018-0816-0156 的版本，vs是2017

 

 

A 、首先webrtc編譯大致流程：
1、gn 生成工程文件

2、ninja調用相關的編譯器實現編譯

所以為了讓自己編譯出來的webrtc庫能夠被自己的vs工程使用關鍵是gn生成工程文件的地方。

webrtc默認的編譯器是clang. 通過她編譯出來的lib有時候我們的vs工程用不了會報如下錯誤：

webrtc.lib : fatal error LNK1136: invalid or corrupt file（只是舉個例子）

所以在使用gn生成工程文件的時候需要帶上  “is_clang=false ” 這樣的參數。例如：

gn gen --ide=vs out/Debug --args="target_winuwp_version=\"8.1\" target_winuwp_family=\"desktop\" use_rtti=true is_clang=false is_component_ffmpeg=false"   (https://groups.google.com/forum/#!topic/discuss-webrtc/9CjnkJ8QVXc)

 

去掉單元測試的命令

gn gen --ide=vs out/Debug --args="target_winuwp_version=\"8.1\" target_winuwp_family=\"desktop\" use_rtti=true is_clang=false libyuv_include_tests=false rtc_include_tests=false libyuv_include_tests=true rtc_use_h264=true"

B、如何使用編譯生成的庫

我們需要相應的lib文件和頭文件

需要注意的是頭文件和lib文件相對路徑必須要正確，所以我們在復制頭文件和lib的時候要保證他們的目錄結構沒有改變，以下命令可以幫組我們

以上是復制頭文件的例子，自己可以變通一下修改成復制lib文件的例子。

C、如何搭建自己的工程

 有了頭文件有了庫文件，那么就開始來搭建我們自己的vs工程吧！！！

以webrtc自帶的peernnection_client為例，首先來看我工程接口截圖

 

1、自己創建一個窗口工程名字自己隨便寫（不詳述）

2、把 webrtc-code\src\examples\peerconnection\client 把這個目錄下的代碼放到步驟1中創建的工程中，並引用

3、把之前復制的頭文件和lib文件的引用基本路徑設置到你的工程用，

4、為項目設置相關的宏

應用webrtc庫需要的宏一般只有三個：NOMINMAX  WIN32_LEAN_AND_MEAN WEBRTC_WIN

但是如果在之后的過程中仍然編譯不過，那么就把peerconnection_client.ninja中涉及到的所有宏都設置到工程里面。

5、為項目添加lib，因為lib很多我就不詳述了，直接列出來（一下只是webrtc相關的lib）

6、設置windows自帶的庫

dbghelp.lib
dnsapi.lib
msimg32.lib
psapi.lib
shlwapi.lib
usp10.lib
version.lib
wininet.lib
winmm.lib
ws2_32.lib
delayimp.lib
crypt32.lib
iphlpapi.lib
secur32.lib
dmoguids.lib
wmcodecdspuuid.lib
amstrmid.lib
msdmo.lib
strmiids.lib

7、編譯

到這一步時語法錯誤和連接錯誤都應該已經沒有了。
