FAQ

Why does sandbox refuse to make?

In local/onlinejudge/judge/sandbox/sand, run the following commands and post output to issues.

uname -a
cc -v
make clean
make

Why pending forever

1. Check whether the judge daemon (judged) is running. The process's name should be php or php.exe. If not, follow README to launch it.
2. If the daemon quit by itself, check your PHP log (default to syslog or Windows NT events log) for detail error messages.

Why so many internal error of ideone.com

Ideone.com will reject the later access if the delay between accesses is too short. You can increase the delay value at settings->site administration->plugins->local plugins->onlinejudge
