1. Download the binary precompiled file

https://github.com/criyle/go-judge/releases

or run on Docker

docker run -it --rm --privileged --shm-size=256m -p 5050:5050 criyle/executorserver

Run binary precompiled files on Ubuntu

First set permissions

chmod +x filename

After that start sandbox

./file name  

c/c++ locale test

Next we open postman for testing and send the request in post form http://IP:5050/run with parameters

{
    "cmd": [{
        "args": ["/usr/bin/g++", "Main.cc", "-o", "a"],
        "env": ["PATH=/usr/bin:/bin"],
        "files": [{
            "content": ""
        }, {
            "name": "stdout",
            "max": 10240
        }, {
            "name": "stderr",
            "max": 10240
        }],
        "cpuLimit": 10000000000,
        "memoryLimit": 104857600,
        "procLimit": 50,
        "copyIn": {
            "Main.cc": {
                "content": "#include <iostream>\nusing namespace std;\nint main() {\nint a, b;\ncin >> a >> b;\ncout << a + b << endl;\n} "
            }
        },
        "copyOut": ["stdout", "stderr"],
        "copyOutCached": ["Main.cc", "a"],
        "copyOutDir": "1"
    }]
}

Our server will return us

"exitStatus": 0,

"files": {
"stderr": "",
"stdout": ""
},
"fileIds": {
"Main.cc": "4EK46KIB",
"a": "LR567VHA"
}
}
]

Next we run him according to the Id of Main

{
    "cmd": [{
        "args": ["a"],
        "env": ["PATH=/usr/bin:/bin"],
        "files": [{

            "max": 10240
        }, {
            "name": "stderr",
            "max": 10240
        }],

            }
        }
    }]
}
