Android.mk ***缺少分隔符。停止。预构建库的LOCAL_SRC_FILES应该只包含一个项目

Question

我克隆了以下来自Github的Telegram回购： https://github.com/DrKLO/Telegram 我使用的是PC而不是Apple。

我在Android Studio中打开了该项目。然后，我将项目与C ++文件链接，这些文件包含在repo中。我用ndkBuild和Android.mk做了这个，它也包含在repo中。

当我尝试使用gradle在Android Studio中构建它时，我收到以下错误消息：

在prebuilt-library.mk中：

Error:(27, 0) *** missing separator.  Stop.

在Android.mk中：

Android NDK: ERROR:C:\Users\...\workspace\project_name\TMessagesProj\jni\Android.mk:avutil: The LOCAL_SRC_FILES for a prebuilt library should only contain one item 

这是Android.mk：

我认为空格，回车和制表符可能存在问题。所以我在我的bash中查看了vi中的Android.mk。这是结果的屏幕截图：

我尝试删除标签并添加了一些，但我仍然无法使其工作，因此构建成功。 也许问题是别的吗？ 非常感谢任何帮助，因为我一直试图解决这个问题2天。

Answer 1

＆＃39;缺少分隔符＆＃39;意味着make期待一个标签或赋值字符并且没​​有找到一次。常见原因是空格而不是制表符（如您所尝试的）或者在源列表中的连续反斜杠字符之后的空格。

但是，我怀疑真正的错误信息是第二个，并且丢失的分隔符是副作用。听起来include $(PREBUILT_STATIC_LIBRARY)行之一是在LOCAL_SRC_FILES中看到源文件列表而不是单个编译库。我不知道这是怎么发生的; makefile在每个组件之后包含$(CLEAR_VARS)，并为每个组件重新定义LOCAL_SRC_FILES。发现共享库目标如何包含opus，libjpeg和libyuv源，这有点奇怪。

或者也许没有TARGET_ARCH_ABI ifeq分支匹配，并且LOCAL_SRC_FILES中的 nothing 包含PREBUILT_STATIC_LIBRARY。您可以通过添加else #error和最里面的ifeq的结尾来检查这一点。

Answer 2

https://android.googlesource.com/platform/ndk/+/master/build/core/prebuilt-library.mk#27

你有条件处理armeabi-v7a，armeabi和x86，但没有任何东西可以用于arm64-v8a，x86_64，mips或mips64。我猜你没有在你的Application.mk中设置APP_ABI := armeabi armeabi-v7a x86？ NDK正在尝试构建其他ABI并为这些ABI找到零源文件。

Answer 3

在Application.mk中设置APP_ABI := armeabi armeabi-v7a x86似乎不适用于新的gradle。

我正在使用gradle 2.2.1。

在Telegram的新版本中，他们添加了

    externalNativeBuild {
        ndkBuild {
            arguments "NDK_APPLICATION_MK:=jni/Application.mk", "APP_PLATFORM:=android-14"
            abiFilters   "armeabi","armeabi-v7a","x86"
        }
    }

到build.gradle。并在这里编写abi过滤器

Answer 4

makefile中有选项卡（屏幕快照中的^I符号）。制表符在make中具有非常特殊的含义，不应用于缩进。用空格替换硬标签，它应该可以工作。
