直接使用GDB在Ubuntu上调试C++ code，有时不是很方便，这里介绍下在Ubuntu上通过Visual Studio Code调试C++ code操作步骤，通过CMake编译。

安装所需依赖：

(1).在Ubuntu上安装Visual Studio Code最新稳定版本1.51.1；

(2).在VS Code中安装C++插件：C/C++ for Visual Studio Code；

(3).在VS Code中安装CMake插件：CMake Tools；

(4).在Ubuntu上安装GCC C/C++、GDB、CMake、make，推荐安装CMake版本3.15及以上。

调试Messy\_Test([https://github.com/fengbingchun/Messy\_Test][https_github.com_fengbingchun_Messy_Test] )中的demo/CppBaseTest目录下code：VS Code中打开命令面板快捷键：Ctrl+Shift+P

(1).将prj/linux\_cmake\_CppBaseTest/CMakeLists.txt拷贝到demo/CppBaseTest目录下，并做调整，调整后的内容如下：

PROJECT(CppBaseTest)
    CMAKE_MINIMUM_REQUIRED(VERSION 3.10)
    
    SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -g -Wall -O2 -std=c11")
    SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}  -g -Wall -O2 -std=c++11")
    # suppornt C++14, when gcc version > 5.1, use -std=c++14 instead of c++1y
    SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}  -g -Wall -O2 -std=c++1y")
    
    # set support C++14
    set(CMAKE_CXX_STANDARD 14)
    set(CMAKE_CXX_STANDARD_REQUIRED ON)
    set(CMAKE_CXX_EXTENSIONS OFF)
    
    MESSAGE(STATUS "path src files: ${PROJECT_SOURCE_DIR}")
    SET(PATH_SRC_FILES ${PROJECT_SOURCE_DIR})
    
    INCLUDE_DIRECTORIES(${PATH_SRC_FILES})
    
    FILE(GLOB CPP_LIST ${PATH_SRC_FILES}/*.cpp)
    FILE(GLOB C_LIST ${PATH_SRC_FILES}/*.c)
    
    ADD_EXECUTABLE(CppBaseTest ${CPP_LIST} ${C_LIST})
    TARGET_LINK_LIBRARIES(CppBaseTest pthread)

(2).将终端定位到demo/CppBaseTest目录下，执行”code .”命令，在当前目录打开VS Code，这将成为你的”workspace”；

(3).打开命令面板：输入或点击CMake:Select a Kit，然后点击GCC 5.4.0；

(4).打开命令面板：输入或点击CMake:Select Variant，然后点击Debug；

(5).打开命令面板：输入或点击CMake:Configure，查看OUTPUT窗口是否正常Configuring done和Generating done，如下图所示:

(6).打开命令面板：输入或点击CMake:Build，查看OUTPUT窗口是否正常显示”Build finished with exit code 0”，如下图所示:

(7).在CppBaseTest.cpp中设置一个断点，打开命令面板，输入或点击CMake:Debug，如下图所示，即可进行调试：
