Incorrect URL in DOMjudge Download Page
by Malcolm Corney 23 Sep '16

23 Sep '16

Hi folks, On the DOMJudge - Download page at https://www.domjudge.org/download you have an instruction for adding your repository GPG key to APT but the URL in the instruction is incorrect. Furthermore, the pipe command requires sudo but the curl command does not. The command as currently displayed is: sudo curl -o - https://domjudge.org/repokey.asc | apt-key add - It should be: curl -o - https://www.domjudge.org/repokey.asc | sudo apt-key add - Hope this helps someone.

Fedora 24 and Submit Client
by Marc Furon 02 Aug '16

02 Aug '16

I am running Fedora 24. I am trying to install DOMjudge 5.1.2 to start preparing for the next regional contest. When I try to run "configure", it gives an error after checking for jsoncpp/json/json.h. This is because it does not exist. json/json.h does exist. When I look at the jsoncpp-devel package, it does not have any files that are in a directory named jsoncpp. The documentation states that json/json.h should be used. I will skip the submit client for now, and we may decide not to use it at all (we have not used it in the past). However, it would be nice to get it to work. I do not have a Debian system handy to see if the include files are different there. Does anyone have suggestions for a resolution to this problem? Regards, Marc

OCaml support
by Parth Mittal 20 Jul '16

20 Jul '16

Hi I tried to add OCaml to the languages, so the compile script I used is: #!/bin/sh # C++ compile wrapper-script for 'compile.sh'. # See that script for syntax and more info. DEST="$1" ; shift MEMLIMIT="$1" ; shift MAINSOURCE="$1" ocamlc -o "$DEST" "$@" exit $? And for run, I left it as default script. But when a submission is judged, it exits with a RunTime Error The Runguard output follows: /home/foobar/domjudge5.1/judgehost/bin/runguard: cannot start `/testcase001/execdir/program': No such file or directory Try `/home/foobar/domjudge5.1/judgehost/bin/runguard --help' for more information. I tried to look for the file, and it does exist, and works like an executable, so I am not sure what is going wrong. For completeness, I also tried to echo the variables being passed to run, and the output in my temporary log file shows sudo -n /home/foobar/domjudge5.1/judgehost/bin/runguard -P 3 -r /home/foobar/domjudge5.1/judgehost/judgings/foobar-3/endpoint-default/c131-s68948-j78769/testcase001/.. --nproc=50 --no-core --streamsize=40000 --user=domjudge-run-3 --walltime=1:2 --cputime=1:2 --memsize=4096000 --filesize=40000 --stderr=program.err --outmeta=program.meta -- /testcase001/execdir/program Please advise on how to proceed. Thank you Parth Mittal

by Myungwoo Chun 11 Jul '16

11 Jul '16

Hi, I want to enable cgroups for Java memory issues and running multiple judgedaemons in AWS EC2 Ubuntu 14.04 Server instance. However, I can't add "quiet cgroup_enable=memory swapaccount=1" since AWS EC2 doesn't use grub. Is there any method to add kernel parameters to AWS EC2 instance? Thanks, Myungwoo Chun
