Using IDE Windows

Using a IDE for compilation of the Proxmark source code on windows you can use these instructions.

Install everything normally

Follow the instructions for each software.

• Proxspace
• Visual Studio Code (vs code)
• C/C++ plug-in

Configure vscode

For the include you can define the vscode c config file like this: I just added : "${workspaceFolder}/include"

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "${workspaceFolder}/include"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "compilerPath": "C:\\cygwin64\\bin\\clang-5.0.exe",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "clang-x64"
        }
    ],
    "version": 4
}

Install GDB in Proxmark Mingw Environment

Once installed you'll need to install gdb. you must not install the latest version

pacman -S mingw-w64-x86_64-gdb  7.10-1 http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-gdb-7.10-1-any.pkg.tar.xz   

And then you just need to create the 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": "${workspaceFolder}/client/proxmark3",
            "args": ["com 9"],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "PATH\\TO\\WHICH\\SHOULD\\FINISH\\WITH\\msys2\\mingw64\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

Adjust the Makefile

don't forget to change the client/Makefile

CC = gcc -g
CXX = g++ -g
LD = g++ -g

Put your breakpoints and let the magic begins :p
