Hi,
I followed all the steps in trying to build the FFMpeg on android.
The build goes fine for some time and then I get the following error:
===========================================================
make: *** No rule to make target `out/apps/ffmpeg-org/armeabi/
libz.so', needed b
y `out/apps/ffmpeg-org/armeabi/libavcodec.a'. Stop.
===========================================================
libz.so is present in the Android NDK (build/platforms/android-5/arch-
arm/usr/lib/libz.so) and the application only needs to link to the
library
the Android.mk in libavformat fools as follows:
===========================================================
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
include $(LOCAL_PATH)/../av.mk
LOCAL_SRC_FILES := $(FFFILES)
LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \
$(LOCAL_PATH)/.. \
external/zlib
LOCAL_CFLAGS += $(FFCFLAGS)
LOCAL_CFLAGS += -include "string.h" -Dipv6mr_interface=ipv6mr_ifindex
LOCAL_SHARED_LIBRARIES := libz
LOCAL_STATIC_LIBRARIES := $(FFLIBS)
LOCAL_MODULE := $(FFNAME)
include $(BUILD_STATIC_LIBRARY)
===========================================================
Referring to some information in the NET I replaced the
LOCAL_SHARED_LIBRARIES := libz
with
LOCAL_LDLIBS := -Lbuild/platforms/android-5/arch-arm/usr/lib -lz
But still get same error. All suggestions to resolve the issue are
welcome :)
Thanks and Regards,
Yadnesh
