Question

我正在尝试按照https://github.com/openstf/android-libjpeg-turbo上的说明操作，并在Windows 10上为Android编译libjpeg-turbo库。

我已安装android-ndk-r10e并在该项目中按如下方式使用它，通过命令行为armeabi编译libjpeg-turbo：

C:\android-ndk-r10e\android-ndk-r10e\ndk-build.cmd APP_ABI=armeabi

但是我遇到了以下问题，我不知道如何解决它：

C:/android-ndk-r10e/build/core/build-binary.mk:464: *** multiple target patterns.  Stop.

同样的结果是使用NDK的r13b版本：

C:/android-ndk-r13b/build/core/build-binary.mk:497: *** multiple target patterns.  Stop.

编辑：

ndk-build.cmd APP_ABI=armeabi DUMP_LOCAL_SRC_FILES的结果：

Answer 1

整个问题出现在由Android.mk引用的Android.mk和基础include $(call all-subdir-makefiles)文件的结构中。在那种情况下，Android NDK试图多次加载源文件。

更正之后，编译工作没有任何问题。

ndk-build ***多个目标模式。停止
