無法在Mac上爲Android構建V8

Question

我嘗試了以下步驟爲Android構建V8。

1.安裝depot_tools

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git 
export PATH=`pwd`/depot_tools:"$PATH" 

運行「取V8」下載代碼和所有依賴性。

cd到v8並運行「make ia32.release」來構建。

使android_arm.release -j16 android_ndk_root = [完整路徑NDK]

步驟3的構建成功並得到了庫。 雖然4失敗，因爲找不到一些標準標題。

Answer 1

不要使用-j參數。

Source: v8 Wiki

可選參數：

-j specifies the number of parallel build processes. Set it (roughly) to the number of CPU cores your machine has. The GYP/make based V8 build also supports distcc, so you can compile with -j100 or so, provided you have enough machines around.

但是現在的編譯器說，他無法找到TargetConditionals.h

.././include/v8config.h:14:11: fatal error: 'TargetConditionals.h' file not found 

Answer 2

你應該安裝的Xcode命令行工具。

1.install xcode。

2.運行命令「xcode-select --install」。

3.make android_arm.release -j16 android_ndk_root = [完整路徑NDK]
