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 ../build

cd ../build

cmake .. \
-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=ON


make -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
    
}
