vscode下調試caffe源碼

caffe目錄：

└── tools //主要使用caffe.cpp，進行調用src下面各個子函數；另外tools/extra下提供一些輔助函數

1. 使用gdb直接調試工程

配置參考：Caffe源碼調試

主要打開：修改Makefile.config：DEBUG := 1 ；生成如下目錄：


lrwxrwxrwx  1 root root     12 1月   3 16:37 build -> .build_debug/
drwxr-xr-x 12 root root   4096 1月   3 16:37 .build_debug/
drwxr-xr-x 12 root root   4096 1月   3 16:37 .build_release/

使用GDB啟動調試，執行gdb --args build/tools/caffe train --solver examples/mnist/lenet_solver.prototxt ；可以直接調試；

rjw@rjw:~/caffe$ gdb --args build/tools/caffe train --solver examples/mnist/lenet_solver.prototxt

2. 使用Vscode進行調試：

配置c_cpp_properties.json 和launch.json ;

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build/tools/caffe",
            "args": ["train","--solver","${workspaceFolder}/examples/mnist/lenet_solver.prototxt"],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}
