jdk_generated: creating a classes.tar file
by Duss Pirmin 09 Aug '19

09 Aug '19

Hello Genodians I'm currently porting jtreg to Genode, so that I can run regression tests for Java. This requires some .class files that aren't currently in the classes.tar from the jdk_generated port. Is there a short description, on how this file was created, so I can create an other version of this file? Best regards, Pirmin

Celebrating 11 years of Genode on August 29, 2019
by Christian Helmuth 07 Aug '19

07 Aug '19

It's summer again and like every year since 2009 we want to celebrate the anniversary of the first public release of Genode with you by a casual barbecue and campfire at the Elbe river banks! For Genode, the past year was full of exciting achievements from the background of the year of Sculpt OS, the annual Microkernel devroom at FOSDEM as well as Hack'n'Hike 2019, the birth of Genodians.org as a virtual place to share stories about Genode, and many technical endeavors, for example, extensive support for NXP i.MX SoCs and the port of OpenJDK. So, if you like to recall the past year's events, glimpse at our next steps, and get together with friends of Genode, we invite you to our anniversary party. Google Maps: http://goo.gl/maps/C0luj 29th of August, 6 pm near Eisenberger Strasse in Dresden Enjoy grilled vegetarian or non-vegetarian food, have a drink, chat with the people of Dresden's operating-systems community, and relax at the nice scenery of the river! If you are going to attend, we would greatly appreciate a short note from you to ease our preparations: info(a)genode-labs.com Hope to see you there Christian -- Christian Helmuth Genode Labs https://www.genode-labs.com/ · https://genode.org/ https://twitter.com/GenodeLabs · /ˈdʒiː.nəʊd/ Genode Labs GmbH · Amtsgericht Dresden · HRB 28424 · Sitz Dresden Geschäftsführer: Dr.-Ing.

import_from_depot size limitation
by Duss Pirmin 06 Aug '19

06 Aug '19

Hello Genodians Is there a limit to the size (number of bytes or number of files) that can be added via import_from_depot (ARCH: imx6, KERNEL: hw)? I had a problem with a run script that sometimes hung (mkfs never completing) or sometimes crashed in different components (ip pointing to Genode::ipc_reply_wait() in ld.lib.so) after upgrading from 19.05 to 19.07. To debug the error I created a small version and step by step increased its size until it was identical to the one with the error. The last difference I found was that the script with the error imported more depot archives. After reducing the list of imported archives the run script now works well. What I think is even stranger, at first I bisected the problem with the original run script. This resulted in commit ac0ecdf855f61 triggering the problem. But as non of my other run scripts showed this kind of error, I suspected that it only uncovered a hidden error in my run script. Could it be, that this is related to the size of the resulting image (about 50MiB for image.elf and 26MiB for uImage)? Best regards, Pirmin

I have used USB to boot up Sculpt demo. I have a problem to use USB to add more components since the system keeps complaining downloading error. Instead I am using RAM and adding more components to Sculpt. How to save Scuplt configurations for system reboot.

Hello everyone, I am struggling with starting a component as a child from another component. At runtime the following error appears: Error: attempt to start dynamic executable without dynamic linker When I am starting the child component directly from init, it works. Does anyone know where the error could come from or where I need to start searching? Tank you in advance, with best regards, Matthias Fesl
