我已经在计算机中安装了Domjudge，包括domserver和法官主机。
我按照domjudge的所有说明进行安装，然后在Domjudge中配置了东西（在localhost / domjudge / ....）并开始了测试竞赛，我使用了一个帐户来提交解决方案，但是我的法官主机（我启动后domjudge目录中的bin / judgedaemon）没有判断并遇到问题：
[...]:~/domjudge/judgehost$ bin/judgedaemon

我不知道这是什么意思，我已经在互联网上寻找它，但没有发现任何东西。
最佳答案
您应该设置编译器，为此只需在ubuntu终端中运行以下命令即可。
sudo apt-get install make sudo debootstrap php5-cli php5-curl php5-json procps \
gcc g++ gcj-jre-headless gcj-jdk openjdk-7-jre-headless openjdk-7-jdk \
ghc fp-compiler
然后，
cd judgehosts/bin
然后，运行udgetdaemon
./judgedaemon
这对我有用。 :)
