[Help]Domjudge on CentOS
by Vũ Linh Nguyễn 14 Dec '15

14 Dec '15

Dear admin, I am a student at University of Information Technology, I'm going to use Domjudge to organize our contest (ACM), I followed your Admin Manual Installation Guide, but I always get error when install Domjudge: -- Before, I get error about jsoncpp-devel. Then, I add --disable-submitclient in configure line. This was not happened. -- After, when I run make, I get error about symbol in /usr/lib/libm.so. File in wrong format. -- Then, I followed Install again, I check url /share/domjudge/www/jury => it a white page. I think I have some mistake when install, but I sure that I followed all of you tutorial. So, can you help me to install this? I'm using CentOS 6.7 with Kloxo installed.

Hi, I cannot log in with the default data admin/admin http://isc.unsaac.edu.pe/cuscontest/public/login.php but when I do this through curl it seems to be working fine: curl --data "login=admin&passwd=admin&cmd=login" http://isc.unsaac.edu.pe/cuscontest/public/login.php what could be the reason for this behaviour, hope you can help me. BTW it was working fine before, I cannot realize why it suddenly took this behaviour, the domjudge version is 4.0.5 and I'm using this version of ubuntu. ubuntu@ip-172-31-28-85:~/domjudge-4.0.5$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.2 LTS Release: 14.04 Codename: trusty ubuntu@ip-172-31-28-85:~/domjudge-4.0.5$ -- Best Regards. Dennis Huillca Portilla <http://about.me/dennisbot>

Distributor ID: Ubuntu Description: Ubuntu 14.04.2 LTS Release: 14.04 Codename: trusty ubuntu@ip-172-31-28-85:~/domjudge-4.0.5$ and the domjudge version is 4.0.5 the same version I've used the last time I've succesfully installed on other ubuntu pc. hope you can explain it a little if that boost is required, I've installed the compilers as described ni the documentation. -- Best Regards.

Has anybody tried to embed source code editor with DOMjudge?
by Br. Anand Shenoi 03 Dec '15

I would like to know if this is possible. In that case, can we have the editor program insert the source code into the db directly?

Yes, Tobias! Would love to have it. The reason is that we are planning to host a competitive programming marathon for 6 months, starting from February 2016.

There are some contest management systems like CodeChef.com, HackerRank.com etc where the compilation and execution can be done through this same editor. Compiling and running (only on samples) is a bit harder, but should be doable as well. Do you want to use DOMjudge as an online judging system? Tobi

Hello Thijs, I saw the code editor (https://ace.c9.io/#nav=about). But couldn’t find an option on how to invoke it in DOMjudge (not sure if it is there). I meant to have compiling and running online. There are some contest management systems like CodeChef.com, HackerRank.com etc where the compilation and execution can be done through this same editor.

You could use the ACE editor already included in DOMjudge and indeed insert to the DB fron there (use the submit_solution function). I believe that this is not part of DOMjudge yet is that it raised workflow questions. How would the team compile and run the program to test it? Or would they submit it untested? What are your ideas about this? Cheers, Thijs

Creating team and user accounts in batch mode
by Howard Cheng 16 Nov '15

16 Nov '15

Hi, I would like to create teams and user accounts in batch (e.g. from a spreadsheet). I'm using DOMjudge 4.0.5 and I see that there is an "Import / export" option, but I can't find much documentation on this. I have also somewhat successfully crafted my own SQL statements to insert tuples into the tables directly, but the problem is that I have to ask for the current id for the auto_increment fields of various tables and match them up. It's not a big deal, but if there is an easier option then I would like to know about it. Thanks.

Judgehost Shared Directories?
by Marc Furon 13 Nov '15

13 Nov '15

I will be running several judgehosts in an environment where the OS image is coming from a flash drive. NFS is also available to the contest server. It looks like several of the judgehost directories (judgings, log, run, and tmp) create sub-directories by hostname and could therefore be shared over NFS. Is there any documentation that describes the best practices for doing that? I read through the administration manual but didn't see anything specifically addressing that topic. Marc
