VSCode使用CMake来debug

使用VSCode远程连接服务器

参考这个链接

配置文件使用CMake来debug

• 建立build.sh脚本文件

• 建立build文件夹

build.sh脚本文件内容如下

cd build    #切换到build文件夹
rm -rf *    #删除build文件夹下内容
cmake -DCMAKE_BUILD_TYPE=Debug ..  #启动cmake来debug，若不debug可注释
cmake ..    #生成makefile各类文件
make -j8    #执行makefile文件

• c_cpp_properties.json

• settings.json

• launch.json这个比较复杂

调试会话前要运行的任务

-"program": "${workspaceFolder}/build/src/exe/colmap"
程序可执行文件的完整路径

-"cwd": "/data6/wcm/document/TanksAndTemples/tankandtemples/intermediate/Playground"
目标的工作目录（存放图片的路径）

-"args": [ "feature_extractor", "--database_path", "/data6/wcm/document/TanksAndTemples/tankandtemples/intermediate/Playground/database.db", "--image_path", "/data6/wcm/document/TanksAndTemples/tankandtemples/intermediate/Playground/images/", ],
传递给程序的命令行参数。
colmap的命令为

$ DATASET_PATH=/path/to/dataset

$ colmap feature_extractor \
   --database_path $DATASET_PATH/database.db \
   --image_path $DATASET_PATH/images

此处的 , 相当于命令行的空格。$DATASET_PATH写绝对路径不会报错。
可以写多个args，把不需要执行的注释掉。
执行完 feature_extractor后，cwd目录下生成了database.db文件
