vscode远程Linux调试c++程序

前提条件

1、Windows下的vscode可以远程连接linux
2、Linux环境已安装g++、gdb
3、安装gdbserver: sudo apt install gdbserver

假设的程序目录

|----------files
	    |------file1.h
	    |------file1.cc
	    |------file2.h
	    |------file2.cc
|----------tests
		|------main.cc
|----------build
|----------bin （放置可执行文件）
|----------CMakeList.txt

1、配置文件

CMakeList.txt

cmake_minimum_required(VERSION 3.0)
project(files)
option(TEST "ON for complile test" ON) 
set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_CXX_FLAGS "$ENV{CXXFLAGS} -rdynamic -O0 -ggdb -std=c++17 -Wall -Wno-deprecated -Werror -Wno-unused-function")

set(LIB_SRC 
    file/file1.cc
    file/file2.cc
    )                                     # (变量 文件名/路径/...)

add_library(file SHARED ${LIB_SRC})  # (库文件名称 STATIC 文件)

add_executable(tests tests/main.cc)       # (可执行文件名称 文件)
add_dependencies(tests file)
target_link_libraries(tests file)  # (库文件名称/可执行文件名称 链接的库文件名称)

SET(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
SET(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}

            "setupCommands": [

        }
    ]
}

task.json
{
	"version": "2.0.0",
	"tasks": [
		{
            "type": "cppbuild",
            "label": "${workspaceFolder}/bin/tests",
            "command": "/usr/bin/gbd",
            "args": [
                "-g",
                "${workspaceRoot}/tests/main.cpp",
                "-o",
                "${workspaceFolder}/bin/tests"  //可执行文件路径
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": [

            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "调试器生成的任务。"
        }
	]
}

2、编译

mkdir build
cd build/
cmake ..
cd ..
cd bin/
./test

vscode终端执行命令：

sudo gdbserver localhost:2334 /home/test/sylar/build/tests  args1 args2 ..
//端口号和launch.json中的端口号一致，若有参数则加入args处

3、设置断点调试
