Question

我知道这个*** missing separator.是非常常见的makefile错误，主要发生在SPACE被滥用而不是TAB时。但这种情况发生在AOSP构建期间，其他人很好地构建。

根据Ubuntu13.10的一些指南，我尝试了AOSP构建。

Ubuntu 13.10 x64
android-4.4_r1

repo init -u https://android.googlesource.com/platform/manifest -b android-4.4_r1
回购同步
source build / envsetup.sh
午餐=＆gt;模型
make -j4

一开始，我收到以下错误

dalvik / CleanSpec.mk：47： * 缺少分隔符。停止。

如果我绕过了上述错误，则会再次在其他模块中发生同样的错误。

似乎有些我自己的配置可以用一些SPACE取代TAB，但我不知道这个错误的确切原因？

提前致谢。：）

TL; DR请在新的shell窗口中执行make操作，而不是在配置模型后在同一个shell中。

[错误]配置模型后，在相同的shell窗口中执行make。

其实我并不确切知道，但这正是我所观察到的 make构建是否应该在新shell中执行？

Answer 2

我遇到了同样的错误。在我的情况下，这是由于一个shell别名回应文字Android没有期待;特别是，我的＆＃34; cd＆＃34;命令被别名以回显新工作目录的完整路径（几年前更常见的行为）。我相信这也会发生在使用CDPATH环境变量的人身上，这会产生类似的输出。

Android构建系统中的build / envsetup.sh脚本最终调用以下函数：

# Get the value of a build variable as an absolute path.
function get_abs_build_var()
{
    T=$(gettop)
    if [ ! "$T" ]; then
        echo "Couldn't locate the top of the tree.  Try setting TOP." >&2
        return
    fi
    (cd $T; CALLED_FROM_SETUP=true BUILD_SYSTEM=build/core \
      make --no-print-directory -C "$T" -f build/core/config.mk dumpvar-abs-$1)
}

＆＃34; cd＆＃34;呼叫将与来自＆＃34; make ...的回声相结合... dumpvar-abs- $ 1＆＃34;调用以生成从函数返回的换行符分隔的字符串，而不是单个路径。这会导致顶级make命令失败并显示错误。

虽然我认为可以更好地编写Android构建函数来返回内部＆＃34; make＆＃34;的结果，但我保留了代码并修改了我的＆＃34; cd＆＃ 34;别名仅在输出路径为stdout时回显结果：

cd () 
{ 
    builtin cd "$@"
    status=$?
    # only echo if stdout goes to a terminal
    [[ -t 1 ]] && echo $PWD
    return $status
}

我希望这有助于某人克服这个常见错误。

我在mac 10.11上构建了android 6.0.1，并遇到了这个错误。我不知道你的情况是否与我的相同，我在这里发布解决方案并帮助其他人。在osx上，原因是bash会话。 get_abs_build_var()中的build/envsetup.sh会切换bash会话，结果中包含Saving session... ...saving history...truncating history files... ...completed.，因此$OUT最后不正确。您可以在主目录中创建.bash_sessions_disable文件以禁用此功能。
