無法在Mac上為Android構建V8

Question

我嘗試按照以下步驟為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"

2. 運行“獲取v8”以下載代碼和所有依賴項。
3. cd到v8並運行“ make ia32.release”進行構建。
4. 使android_arm.release -j16 android_ndk_root = [ndk的完整路徑]

第3步成功構建並獲得庫。 雖然4失敗，因為找不到標准標頭。

Answer 1

不要使用-j參數。

資料來源：v8 Wiki

可選參數：

-j指定並行構建過程的數量。 （大約）將其設置為計算機具有的CPU內核數。 基於GYP / make的V8版本也支持distcc，因此只要周圍有足夠的機器，就可以使用-j100進行編譯。

但是現在編譯器說，他找不到TargetConditionals.h

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

Answer 2

您應該安裝xcode命令行工具。

1.安裝xcode

2.運行命令“ xcode-select --install”。

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