linphone on windows构建错误

Question

我已经从Github下载了Android的linphone。我还遵循了自述文件中的所有说明。问题是，当我运行ndk-build命令时，它会产生下面的错误。

Android NDK: ERROR:jni/..//submodules/externals/build/ffmpeg/Android.mk:avutil-linphone: LOCAL_SRC_FILES points to a missing file
Android NDK: Check that jni/..//submodules/externals/build/ffmpeg/arm/libavutil/libavutil-linphone-arm.so exists  or that its path is correct
/cygdrive/c/development/android-ndk-r9b/build/core/prebuilt-library.mk:45: *** Android NDK: Aborting    .  Stop.

what this error mean ? & how can i resolve this?我已经花了很多时间来搜索这个错误，但没有成功...我的操作系统是Windows7&我使用cygwin作为命令。

我在SO上找到了同样的问题

Android NDK error when using FFmpeg in Android?

上面写着Basically problem was with ffmpeg lib.I was not able to compile ffmpeg lib on Windows 7. I switched to Ubuntu & tried AppUnite & after spending so many hours it was working.

is it not possible to build linphone on windows ???

虽然我不熟悉linphone库，但从一般的观点来看，您可以将libavutil-linphone-arm.so放在‘workspace/ you put /lib’目录下，

然后修改位于‘workspace/ your Android.mk /jni’下的Android.mk：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := avutil-linphone-arm
LOCAL_SRC_FILES := ../lib/libavutil-linphone-arm.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE    := yourownmodule
LOCAL_SRC_FILES := yourownmodule.cpp
LOCAL_LDLIBS    := -llog -landroid
LOCAL_STATIC_LIBRARIES := 
LOCAL_SHARED_LIBRARIES :=  avutil-linphone-arm

include $(BUILD_SHARED_LIBRARY)

有关共享库的ABI选择，可以参考android-ndk/docs下的PREBUILTS.html
