Linux小白求助，使用Ubuntu 20.4，安装后，在root用户下，控制台运行。然后用postman发送如下请求：
{ "cmd": [ { "args": [ "/usr/bin/g++", "a.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": { "a.cc": { "content": "#include <iostream>\nusing namespace std;\nint main() {\nint a, b;\ncin >> a >> b;\ncout << a + b << endl;\n}" } }, "copyOut": [ "stdout", "stderr" ], "copyOutCached": [ "a.cc", "a" ], "copyOutDir": "1" } ] }
返回错误结果：
[ { "status": "Internal Error", "exitStatus": 0, "error": "execve: cgroup failed to set memory limit open /sys/fs/cgroup/executor_server/230144310/memory.max: permission denied", "time": 0, "memory": 0, "runTime": 0, "files": { "stderr": "", "stdout": "" }, "fileIds": { "a.cc": "D4DRDGIY" }, "fileError": [ { "name": "a", "type": "CopyOutOpen", "message": "open a: no such file or directory" } ] } ]
