vscode调试第一篇

1. 插件

c/c++, cmake, cmake tools

2. 项目工程

对于我的项目需要用到很多的三方库，三方库的版本又会有很多，一般都是用cmake编译安装到指定的位置，最好的方式是三方库都放到一个非系统的文件夹下，后面要修改版本也和系统不冲突。这样的话就需要cmake在编译的时候find_package时指定库的搜索路径。每个开发人员的路径都不一样，所以这些路径都不会在cmakeLists里面有体现，都是在脚本里面指定。

代码量接近10万的项目。

例如下面的bash脚本是我的编译执行脚本:

# if [ -d "../build" ]; then
#     rm -rf ../build
# fi
mkdir -p ../buildcd ../buildcmake .. \
-DCMAKE_BUILD_TYPE=Release \
-DOpenCV_DIR="/media/xp/data/3rd_party/opencv481/lib/cmake/opencv4" \
# ..........其他的库
-DOCL_ROOT="/media/xp/data/3rd_party_lib/opencl_sdk/2024.05.08/gnu/share/cmake/OpenCL" \
-DOpenCL_INCLUDE_DIR="/media/xp/data/3rd_party_lib/opencl_sdk/2024.05.08/gnu/include" \
-DOpenCL_OpenCLUtilsCpp_LIBRARY="/media/xp/data/3rd_party_lib/opencl_sdk/2024.05.08/gnu/lib/libOpenCLUtilsCpp.so" \
-DOpenCL_OpenCLUtils_LIBRARY="/media/xp/data/3rd_party_lib/opencl_sdk/2024.05.08/gnu/lib/libOpenCLUtils.so" \
-DOpenCL_OpenCL_LIBRARY="/media/xp/data/3rd_party_lib/opencl_sdk/2024.05.08/gnu/lib/libOpenCL.so" \
-DOpenCL_INCLUDE_DIR="/media/xp/data/3rd_party_lib/opencl_sdk/2024.05.08/gnu/include" \
-DBUILD_SHARED_LIBS=ONmake -j32../build/demo/test

3. vsode的配置

setting.json

bash 命令中的cmake -DXXX=YYY的可以在里面添加cmake.configureSettings项，指定XXX:YYY

}

c_cpp_properties.json

vscode调试的时候跳转三方库头文件啥的，在这里面的includePath里面配置添加；
阅读代码会有很多宏变量，可以在defines中定义；

{"configurations": [{"name": "Linux","includePath": ["${workspaceFolder}/**","${workspaceFolder}/modules/surround_view_3d/include","${workspaceFolder}/modules/casting/include","/usr/local/include/glog","${workspaceFolder}/modules","/usr/local/include/opencv4","${workspaceFolder}/modules/widget/include","${workspaceFolder}/modules/surround_view_3d/include/common","/media/xp/data/3rd_party_lib/opencl_sdk/2024.05.08/gnu/include","/media/xp/data/3rd_party_lib/opencl_sdk/2024.05.08/gnu/include/CL",],"defines": ["USE_OCL=0"],"compilerPath": "/usr/bin/gcc","cStandard": "c17","cppStandard": "gnu++17","intelliSenseMode": "linux-gcc-x64"}],"version": 4}

4. 启动调试
