Ich versuche, die dlib Bibliothek für android-ndkGebäude DLIB für Android NDK
ich die dlib Bibliothek heruntergeladen zu bauen und schrieb die Android.mk und Application.mk Datei.
Android.mk
LOCAL_PATH := $(call my-dir)
# Define the shared library module used by the calling JNI C++ module
include $(CLEAR_VARS)
LOCAL_MODULE := dlib
LOCAL_C_INCLUDES := $(LOCAL_PATH)/dlib
LOCAL_SRC_FILES += \
../$(LOCAL_PATH)/dlib/dlib/threads/threads_kernel_shared.cpp \
../$(LOCAL_PATH)/dlib/dlib/entropy_decoder/entropy_decoder_kernel_2.cpp \
../$(LOCAL_PATH)/dlib/dlib/base64/base64_kernel_1.cpp \
../$(LOCAL_PATH)/dlib/dlib/threads/threads_kernel_1.cpp \
../$(LOCAL_PATH)/dlib/dlib/threads/threads_kernel_2.cpp
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_C_INCLUDES)
include $(BUILD_STATIC_LIBRARY)
TOP_LEVEL_PATH := $(abspath $(LOCAL_PATH)/..)
$(info TOP Level Path : $(TOP_LEVEL_PATH))
EXT_INSTALL_PATH = $(TOP_LEVEL_PATH)/third_party
OPENCV_PATH = $(EXT_INSTALL_PATH)/opencv/jni
OPENCV_INCLUDE_DIR = $(OPENCV_PATH)/include
include $(CLEAR_VARS)
OpenCV_INSTALL_MODULES := on
OpenCV_CAMERA_MODULES := off
OPENCV_LIB_TYPE := static
include $(OPENCV_PATH)/OpenCV.mk
LOCAL_MODULE := dlib-lib
LOCAL_C_INCLUDES += \
$(OPENCV_INCLUDE_DIR)
LOCAL_DLIBS := -lm -llog -ldl -lz -lnigraphics
LOCAL_CPP_FLAGS += -frtti -fexceptions -std=c++11
LOCAL_STATIC_LIBRARIES += dlib
include $(BUILD_SHARED_LIBRARY)
Application.mk
NDK_TOOLCHAIN_VERSION := clang
APP_ABI := armeabi-v7a arm64-v8a x86 x86_64 mips64 mips armeabi
APP_CPPFLAGS := -std=c++11 -frtti -fexceptions
APP_PLATFORM := android-8
APP_STL := gnustl_static
ich die Bibliothek bauen konnte, dann kopiert ich die Bibliothek auf meinem jniLibs Ordner. Ich habe die generierte Bibliothek in meine CMakeList.txt in Android-Studio aufgenommen.
CMakeList.txt
add_library(lib_dlib SHARED IMPORTED)
set_target_properties(lib_dlib PROPERTIES IMPORTED_LOCATION "${CMAKE_SOURCE_DIR}/src/main/jniLibs/${ANDROID_ABI}/libdlib-lib.so")
target_link_libraries(native-lib ${log-lib} lib_dlib)
include_directories("${CMAKE_SOURCE_DIR}/generateLibs/jni/dlib")
Ich habe die Funktionen in dlib von einem nativen cpp Programm im android-studio genannt.
Aber ich bekomme den folgenden Fehler.

Was ist mit geeigneten 'include_directories()' Anruf? Dies würde dem Compiler helfen, Header zu suchen. Beachten Sie, dass 'target_link_libraries()' dem Compiler in dieser Task nicht hilft. – Tsyvarev
@Tsyvarev Sie sagen also, 'include_directories()' zu verwenden, um die Bibliothek zu erstellen, anstatt 'Android.mk' und' Application.mk' zu verwenden? – jgm
Nein, das ist alles über Sie 'CMakeLists.txt' Skript. Wenn Sie die Eigenschaft * IMPORTED_LOCATION * der Bibliothek festlegen, teilen Sie CMake mit, wo sich diese Bibliothek befindet. Ähnliche Dinge sind für den Kopfzeilen-Suchpfad erforderlich. – Tsyvarev
