VSCode C++ 环境配置

基础要求

系统装有 gcc/g++ 和 cmake 以及 VSCode

安装插件

  • C/C++ (c/c++ 语法)
  • C++ Intellisense (代码格式化)
  • CMake (cmake 语法高亮)
  • CMake Tools

添加配置

CMake

按快捷键 Ctrl+Shift+P 调出控制台， 输入 cmake ，选择CMake:Configure 或者 CMake:Quick Start 开始配置

  1. 选择 gcc 编译工具版本

    cmake

  2. 根据提示创建 CMakeLists.txt， 选择 Create， 创建新文件， 选择Locate 打开已有文件

    cmake

  3. 若 2 选择Create, 则按提示创建文件，输入项目名称，选择输出类型，就会生成 CMakeLists.txt 文件

    cmake cmake

当状态栏出现如下图表时，则表明配置完成，可以选择 Build 尝试编译

cmake

CMakeLists.txt

该配置是使用pkgconfig编译成动态库， 如需其他格式，自行修改

cmake_minimum_required(VERSION 3.0.0)
project(gbsip VERSION 0.1.0)

include(CTest)
enable_testing()

## there is two way to import 3Party Library, please choose one
### 1. import 3Party Library use pkgconfig
set(ENV{PKG_CONFIG_PATH} /home/xxx/exosip/lib/pkgconfig)
find_package(PkgConfig)
pkg_check_modules(SIP REQUIRED libeXosip2 libosip2 libosipparser2 libcares)
include_directories(${SIP_INCLUDE_DIRS})
link_directories(${SIP_LIBRARY_DIRS})

### 2. import 3Party Library use relative path
# include_directories(${PROJECT_SOURCE_DIR}/include)
# link_directories(${PROJECT_SOURCE_DIR}/lib/x64)

## set output directory
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY  ${PROJECT_SOURCE_DIR}/build/out)

## The compilation output can be a library or an executable file
###> .so is dynamic library
add_library(gbsip SHARED gbsip.cpp)

###> .a is static library
# add_library(gbsip STATIC gbsip.cpp)

###> exe
# SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x")
# aux_source_directory(. SRC_LIST)
# add_executable(gbsip ${SRC_LIST})


## link thirdlib
target_link_libraries(gbsip ${SIP_LIBRARIES})
# target_link_libraries(gbsip libcares.so libosipparser2.so libosip2.so libeXosip2.so)

## ouput version, if output is `.so`, please open this
SET_TARGET_PROPERTIES(gbsip PROPERTIES VERSION 0.1.0 SOVERSION 0)


set(CPACK_PROJECT_NAME ${PROJECT_NAME})
set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
include(CPack)

Debug

设置好 CMake 后，打开 .cpp 文件， 按快捷键 Ctrl+Shift+D 打开调试面板，���击 运行和调试, 根据系统情况选取不同的 C++ ,如下图所示：

Debug

然后根据需要选择不同版本的编译器配置，会生成 lunch.json 和 tasks.json, 根据调试需求更改相应的参数

Debug

C++ configure

按快捷键 Ctrl+Shift+P 调出控制台, 输入 c++，选择 C/C++编辑配置 UI界面或者 JSON 格式进行配置，
