我感覺谷歌的官方文檔本身就不完善，導致我沒辦法詳解，很多配置都是看?別人寫的?慢慢摸索出來的。windows篇章里，我實現了一個海康node插件，linux版里，我同樣實現了這個功能.

部分指令的解釋：

一，條件

可以根據 conditions 實現條件編譯，比如在 windows 平臺下，或者 Linux 平臺下引用不同的庫。

二，編譯器鏈接器指令

?

windows 下，我使用的微軟的cl（c/c++）?編譯器，所以可以傳入編譯和鏈接指令。上圖所示就是如何配置字符集。

那么gyp支持哪些配置呢？在查看了gyp的源碼之后，我發現，只支持這么幾種：

?那么這些指令對應的文檔在哪里呢？大家可以看這里：配置選項

?

細節方面，大家自己看MSDN吧，然后自己嘗試配置看看。

再就是linux一些配置：

?

關于linux的一些配置，如果涉及到引用第三方庫，則需要處理好庫文件路徑。對于這個問題，大家可以移步看看我的這篇文章。

以上，就是gyp配置文件的一些粗解，其實其最終目的，就是配置一些參數，傳給編譯器鏈接器使用的。

?

總結
