vscode下C++开发环境搭建

安装gcc，clang

sudo apt update
sudo apt install gcc
sudo apt install clang
sudo apt install gcc-10
...

gcc,clang版本切换

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 1 --slave /usr/bin/g++ g++ /usr/bin/g++-9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 2 --slave /usr/bin/g++ g++ /usr/bin/g++-10
update-alternatives --config gcc
...

vscode 安装cmake-tools

crtl+shift+p: cmake:quick start

配置相应的CMakeLists.txt(可以在vscode选择编译器，或者选择由cmake推定)

gcc的CMakeLists.txt参考如下：

cmake_minimum_required(VERSION 3.0.0)
project(test1 VERSION 0.1.0)
set(CMAKE_C_STANDARD 11)
   
   
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17")
   
add_executable(test1 main.cpp)
   
set(CPACK_PROJECT_NAME ${PROJECT_NAME})
set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})

clang的CMakeLists.txt参考如下：

cmake_minimum_required(VERSION 3.2.0)
project(test2 VERSION 0.1.0)
   
   
find_package(LLVM REQUIRED CONFIG)
   
message(STATUS "Found LLVM ${LLVM_PACKAGE_VERSION}")
message(STATUS "Using LLVMConfig.cmake in: ${LLVM_DIR}")
   
set(CMAKE_C_STANDARD 11)
set(CMAKE_CXX_STARDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17")
   
include_directories(${LLVM_INCLUDE_DIRS})
add_definitions(${LLVM_DEFINITIONS})
   
add_executable(test2 main.cpp)
   
# that we wish to use
llvm_map_components_to_libnames(llvm_libs support core irreader)
    
# Link against LLVM libraries
target_link_libraries(test2 ${llvm_libs})

使用cmake插件的build功能生成相应的可执行文件，使用vscode的调试功能生成launch.json与tasks.json,删除tasks.json，删除launch.json这一行
```
"preLaunchTask": "C/C++: g++-10 build active file",
```
并配置launch.json
```
"program": "${workspaceFolder}/build/leedcode-cpp",
```
接下来就可正常使用vscode的运行与调试功能了。

settings.json与c_cpp_properties.json

settings.json如下：

{
    "vsicons.presets.angular": true,
    "editor.fontSize": 16,
    "debug.console.fontSize": 14,
    "terminal.integrated.fontSize": 14,
    "window.zoomLevel":1.2,
}

c_cpp_properties.json如下：

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/clang",
            "cStandard": "c11",
            "cppStandard": "c++20",
            "intelliSenseMode": "clang-x64",
            "configurationProvider": "ms-vscode.cmake-tools"
        }
    ],
    "version": 4
}

待解决问题，调试时如何直观的查看，标准库容器变量的值如stack、vector、list…?
