利用Visual Studio调试WSL下的C++工程

这里写了一个基于Qt5的控制台的小代码：

#include <QCoreApplication>
#include <QDebug>

int main(int argc, char** argv)
{
	QCoreApplication a(argc, argv);

    qDebug() << "Application started";
    int testValue = 42;
    qDebug() << "Test value:" << testValue;

	return a.exec();
}

工程使用了CMake工程:

cmake_minimum_required(VERSION 3.15)

project(WSLwithVS)

set(CMAKE_AUTOMOC ON)

find_package(QT NAMES Qt5 Qt6)
find_package(Qt${QT_VERSION_MAJOR} CONFIG COMPONENTS Core REQUIRED)

add_executable(WSLwithVS main.cpp)

target_link_libraries(WSLwithVS Qt${QT_VERSION_MAJOR}::Core)

确保WSL里面有编译器、Ninja、gdb、qtbase5-dev和常用的中文字体fonts-wqy-zenhei、fonts-wqy-microhei

sudo apt install gcc g++ ninja-build cmake gdb qtbase5-dev fonts-wqy-zenhei fonts-wqy-microhei

开始编译调试

1. 右键点击CMakeLists.txt文件，选择配置"WSLwithVS"

   我这里遇到一点小问题在1> CMake 生成完毕列出现了错误，我暂时的解决方法：

   cd ~/.vs/WSLwithVS
   ninja -C out/build/
   

2. 在使用ninjia生成完毕后重复步骤1，输出结果如下

   1> 已为配置“Qt-Debug”启动 CMake 生成。
   1> 在 /usr/bin/cmake 上找到 cmake 可执行文件。
   1> /usr/bin/cmake -G "Ninja"   -DCMAKE_BUILD_TYPE:STRING="Debug" -DCMAKE_CXX_FLAGS:STRING="-DQT_QML_DEBUG"   /home/lxy/.vs/WSLwithVS/CMakeLists.txt;
   1> [CMake] -- Configuring done
   1> [CMake] -- Generating done
   1> [CMake] -- Build files have been written to: /home/lxy/.vs/WSLwithVS/out/build
   1> [CMake] 
   1> 已提取 CMake 变量。
   1> 已提取源文件和标头。
   1> 已提取代码模型。
   1> 已提取包含路径。
   1> CMake 生成完毕。
   

3. 设置断点、启动调试

   
   调试控制台信息:
