使用cmake构建时找不到android/log.h

Question

我已经开始在Android Studio中使用Android NDK进行开发,但由于它没有适当的C++支持,所以它很痛苦.所以我尝试创建一个cmake项目来构建我的东西.我已经使用了android-cmake,到目前为止它运行良好,除了事实<android/log.h>,<android/native_window.h>并且可能<android/*>找不到所有包含物.IDE(CLion)也因为它而将它们标记为缺失.我错过了什么CMakeLists.txt吗？

这是CMakeLists.txt:

cmake_minimum_required(VERSION 2.8.4)
project(App)

SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake)

include(AndroidNdkGdb)
include(AndroidNdkModules)

android_ndk_gdb_enable()

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/src/main/libs/armeabi-v7a)

set(LIBRARY_DEPS GLESv2 android log)

include_directories(${PROJECT_SOURCE_DIR}/src/main/lib/armeabi-v7a/freetype/include/freetype2)

file(GLOB_RECURSE SRCS *.cpp)
file(GLOB_RECURSE HDRS *.h)

add_library(nativeegl SHARED ${SRCS} ${HDRS})
target_link_libraries(nativeegl log android)

android_ndk_gdb_debuggable(nativeegl)

和cmake发射参数:

-DCMAKE_TOOLCHAIN_FILE=android.toolchain.cmake \
-DANDROID_NDK=/opt/android-ndk -DCMAKE_BUILD_TYPE=Debug \
-DANDROID_ABI="armeabi-v7a" -DANDROID_STL=gnustl_static \
-DANDROID_NATIVE_API_LEVEL=android-21

这是我在工作室中构建的原始Android.mk工作正常:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := nativeegl
LOCAL_SRC_FILES := $(patsubst $(LOCAL_PATH)/%, %, $(wildcard $(LOCAL_PATH)/*.cpp))

LOCAL_C_INCLUDES :=
LOCAL_CFLAGS := -std=c++11 -O2 -Wtype-limits -Wmissing-field-initializers -Wreturn-type -Wuninitialized

LOCAL_LDLIBS := -llog -landroid -lEGL -lGLESv2
LOCAL_STATIC_LIBRARIES := android_native_app_glue ndk_helper freetype

include $(BUILD_SHARED_LIBRARY)

$(call import-add-path,$(LOCAL_PATH)/../lib/$(TARGET_ARCH_ABI))
$(call import-module,freetype)

和Application.mk:

APP_STL := gnustl_static
APP_PLATFORM := android-10
APP_ABI := armeabi-v7a

感谢您的帮助.

实际问题在于一个 android-cmake 文件中的错误以及 CMakeLists.txt 中的错误 cmake 变量。它是怎么发生的？可能我已经遵循了旧版本 android-cmake 的一些教程。以下是 CMakeLists.txt 现在的样子：

cmake_minimum_required(VERSION 2.8.4)
project(App)

SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake)

include(AndroidNdkGdb)
include(AndroidNdkModules)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(LIBRARY_OUTPUT_PATH ${PROJECT_BINARY_DIR}/src/main/libs/armeabi-v7a)

set(LIBRARY_DEPS GLESv2 android log EGL)

include_directories(${PROJECT_SOURCE_DIR}/src/main/lib/armeabi-v7a/freetype/include/freetype2)

file(GLOB_RECURSE SRCS *.cpp)
file(GLOB_RECURSE HDRS *.h)

android_ndk_gdb_enable()

add_library(nativeegl SHARED ${SRCS} ${HDRS})
target_link_libraries(nativeegl log android)

android_ndk_gdb_debuggable(nativeegl)
