Hi all, We're planning to again organize one or two hackathons in the upcoming two months to advance the API and other tasks, especially focussing on the upcoming ICPC World Finals. If you're interested in joining (non-core/new developers also very welcome!) please fill in the poll: https://doodle.com/poll/vxvs9ri9siq7esgw We're planning to do a full day, roughly between 10 - 20h Europe time, but everyone is welcome to join in when they have time.

Do installing from https://www.domjudge.org/icpc-kotlinc_1.1.4-3~icpc_all.deb, will install kotlin to the chroot environment? Do I need any more steps to make it available to chroot enviroment? Just installing the package above is not enough. What you need to do is to install the package _inside_ the chroot. The steps you need to take are (roughly, it may vary slightly depending on your environment): - copy icpc-kotlinc_1.1.4-3~icpc_all.deb somewhere into your chroot - enter the chroot: sudo chroot /chroot/domjudge (or whatever path you build it at) - install the package there: dpkg -i /path/to/icpc-kotlinc_1.1.4-3~icpc_all.deb - if dpkg complains about missing dependencies, run 'apt-get -f install' or install them and then try again - exit the chroot and test if it works You might need to bind mount /proc, /dev, and/or /dev/pts inside the chroot to make apt-get work. See the domjudge chroot-start-stop.sh file for examples how to do so.

[Fwd: Re: Kotlin Problem]

Thanks for the quick reply again, Sir. I was supiscious about kotlin is not installed in chroot enviroment too but i have no idea how to install them at chroot enviroment. Before you reply, I have managed to make kotlin work by compiling using kotlinc to make java executable (jar), and finally running the program using java and -jar parameter on addition other java parameter. But I worry that it will create future unknown problem. Anyway , I need more guidance to install kotlin at chroot mode. Do installing from https://www.domjudge.org/icpc-kotlinc_1.1.4-3~icpc_all.deb, will install kotlin to the chroot environment? Do I need any more steps to make it available to chroot enviroment?

Compilation is done outside the chroot, so you need kotlinc available there, but the program is executed inside, so you need kotlin and the Kotlin support libraries inside there.

Kotlin Problem
by Andrew Jauhari 13 Jan '18

13 Jan '18

Dear Domjudge - Developers, Hello again, I have problem to integrate Kotlin compiler in judgehost. For information, I'm using ubuntu 16.04 and I was installing kotlin from sdkman. But when compiling, it seems that domjudge cannot find kotlinc and kotlin. I have try to move kotlinc and kotlin to /bin/ directory. It seems to solve kotlinc problem, but domjudge still cannot execute kotlin. When I try to go to directory where /testcase001/execdir/program resides, and then execute it myself. It seems work and no problem. Trying to re-chroot seems doesn't fix this too. Looking forward for your replay.

About Domjudge version 6.0.0 stable version Plan
by Andrew Jauhari 05 Jan '18

05 Jan '18

Dear Domjudge Developers, I'm Andrew Jauhari from Mikroskil, an education institution in Medan, Indonesia. We are going to hold event that will use latest version of domjudge, and version 6.0.0 is prefered, but currently it is not the stable one. From what I see, the current stable version is 5.3.2 and was just released at 29 Dec 2017. I want to ask if domjudge v 6.0.0 stable will be released soon or not ? Can you give information about this, so I can proceed whether I need to use current stable version or wait for stable version of Domjudge 6.0.0 I'm looking forward for your reply. Thanks before.
