I have a pre-built shared libray called "tshark.so" that I am attempting to link whenever I build another shared library (libwireshark_helper.so). libtshark.so is in $(LOCAL_PATH). Here is my Android.mk
LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS) NDK_MODULE_PATH := $(LOCAL_PATH) LOCAL_SRC_FILES:= wireshark_helper.c LOCAL_MODULE := libwireshark_helper LOCAL_PREBUILT_LIBS := libtshark.so LOCAL_C_INCLUDES += jni/libusb-compat/libusb jni/wispy jni/libpcap jni/libwireshark jni/libglib jni/libglib/glib jni/libglib/android jni/libwireshark/epan jni/libwireshark/epan/dissectors LOCAL_SHARED_LIBRARIES := libc libusb libusb-compat libwispy libpcap libglib-2.0 libgmodule-2.0 libnl libtshark LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -L$(LOCAL_PATH) -llog -ltshark -lgcc -lz include $(BUILD_SHARED_LIBRARY) For example, the 'tshark' library contains the method 'tshark_log_handler' which is shown here:
$ arm-eabi-nm libtshark.so | grep tshark_log_handler 005d298c t tshark_log_handler However, when I attempt to build, I get the error:

It is in my shared library, and there is a "-ltshark" in my gcc command. I do not get an error that it cannot find this library.
