C++ 如何在Debian 10上为板载SDK项目创建CMakeList.txt

我想编译我自己的项目。我的

**make**

有错误<代码>cmake..工作正常

我试图在/boardsdk/sample/platform/telemetry中编译这个示例。 我在遥测目录中创建了mkdir和cd

这是我的CMakeList.txt

cmake_minimum_required(VERSION 2.8)
project(djiosdk-telemetry-sample)

# Compiler flags: link with pthread and enable C++11 support
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread -g -O0")

# Tell the project where osdk-core is located
if(NOT ONBOARDSDK_SOURCE)
    set(ONBOARDSDK_SOURCE "/home/pi/Onboard-SDK/osdk-core")
    #set(ONBOARDSDK_SOURCE "/usr/local/include")

endif()

# Specify locations for osdk-core headers
include_directories(${ONBOARDSDK_SOURCE}/api/inc)
include_directories(${ONBOARDSDK_SOURCE}/utility/inc)
include_directories(${ONBOARDSDK_SOURCE}/hal/inc)
include_directories(${ONBOARDSDK_SOURCE}/protocol/inc)
include_directories(${ONBOARDSDK_SOURCE}/platform/linux/inc)
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/../hal)
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/../osal)
include_directories(include /usr/local/include)
include_directories(${ONBOARDSDK_SOURCE}/../sample/core/inc)

# User-code related project files
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/../common)
FILE(GLOB SOURCE_FILES *.hpp *.cpp
    ${CMAKE_CURRENT_SOURCE_DIR}/../common/dji_linux_environment.cpp
    ${CMAKE_CURRENT_SOURCE_DIR}/../common/dji_linux_helpers.cpp
    main.cpp
    telemetry_sample.cpp
    )

if (OSDK_HOTPLUG)
    FILE(GLOB SOURCE_FILES ${SOURCE_FILES} ${CMAKE_CURRENT_SOURCE_DIR}/../hal/hotplug/*.c)
endif ()

# Target and linking
add_executable(${PROJECT_NAME} ${SOURCE_FILES})
target_link_libraries(${PROJECT_NAME} djiosdk-core)

这是制作后的结果

我经常链接CXX可执行文件djiosdk遥测样本。 主要问题在于“未定义的引用”。 我根据以下内容创建CMakeList.txt：

我应该怎么做？

创建您自己的项目所需的正确的CMakeList.txt（基于遥测样本的示例）：

cmake_最低要求（2.8版）

我不确定osdk库的具体情况，但似乎您正在尝试将可执行文件链接到

djiosdk core

。您需要指定CMake应该如何查找

djiosdk core.a（或.so）

。如果您知道使用指定它，您知道如何实现查找此核心的代码吗？我开始创建cmake。我正在使用：

git clone&&cd&&mkdir build&&cd build&&cmake..&&make-j4&&make-install

->这应该将lib放在/usr/local/lib中，并在/usr/local/include中包含文件--您可以从这里开始我添加了：link_库（dji链接器）link_库（${ONBOARDSDK_-SOURCE}/linker/${ARCH}/lib dji linker.a）target_链接库（${PROJECT_-NAME}PUBLIC${ONBOARDSDK_-SOURCE}/linker/${ARCH}/lib/libdji linker.a）target_include_目录（${PROJECT_NAME}PUBLIC${LIBUSB_1_include_DIRS}）target_链接库（${PROJECT_NAME}PUBLIC${LIBUSB_1_libraries}）target_链接库（${PROJECT_NAME}PUBLIC${FFMPEG_libraries}）target链接库（${PROJECT_NAME}PRIVATE advanced sensing）但我仍然有一些错误。我想有一个库要添加，但不知道是哪个库。
