my Sculpt Early Adopters experiences
by Guido Witmond 09 Jun '18

09 Jun '18

Hi Genodians, Last week I've played with the Sculpt EA system. It looks great. And with the new booting code, it runs on my hardware. It boots on my old Gigabyte H67MA-USB3-B3 mobo with a Pentium G620 processor and 16 GB RAM. I didn't connect any Sata disks yet. Built-in Intel video to VGA and DVI-D display. No RS232 output, regrettably. (Another box, a DELL optiplex 360 PC, does do RS232 after grub but lacks recognised display adapter and reboots). My experiences: Things that work: - booting, OK; - Leitzentrale OK; - Disk, network and debug log OK; - live reconfiguration of display from VGA to DVI OK; - wired network config OK; however the system does not respond to ping; - Deploy backdrop OK, 2048 game OK, noux OK. After that I had some less luck. - Some downloads seem to hang. It could either be out of RAM (config), or a lost packet that is not detected. I'm using the RAM-disk that gets to 64MB in size. (I remember, but could not reproduce) it going to 128MB - Expanding the GENODE-partition on the USB-stick makes it unbootable. The system can't find and start Grub anymore. This happened repeatable both with a Kingston 8GB USB2 stick as well as with a Sandisk 32GB USB3 stick. I haven't been able to test the virtual machine with debian payload due to the download errors. Questions: - is there a way to send the debug log via ethernet? - did I miss some configuration settings that made the downloads get stuck? Cheers, Guido.

Sculpt TC - Error Building "image/disk"
by John J. Karcher 07 Jun '18

07 Jun '18

Hello, I am happy to report a very smooth initial experience with Sculpt TC running in VirtualBox. I followed the tutorial (skipping the parts about virtualization, of course), and everything went well, with the exception of the minor error I will describe below. The Sculpt Manager is surprisingly convenient and mature, and the under-the-hood improvements are impressive as always. I really like the direction things are moving! My only problem was building the "image/disk" version of the image. For development, I am running an up-to-date Debian Unstable, which has worked well for me so far. Here is the relevant part of the output: checking configuration syntax CHECK init using 'core-nova.o' as 'core.o' Run script aborted because gdisk is not installed Makefile:312: recipe for target 'run/sculpt' failed make: *** [run/sculpt] Error 1 In fact, "gdisk" is installed, but it doesn't run under a normal user. I could hack the scripts to use "sudo", but I thought I'd check here first, in case there is a simple solution (since Ubuntu and Debian usually operate similarly). I obviously don't expect Linux distro tech support - if there isn't an easy answer, I'll just install Ubuntu. Thanks! -- John J. Karcher devuser(a)alternateapproach.com

use of make functions while building libraries in depots
by Pirmin Duss 04 Jun '18

04 Jun '18

Hello, While debugging the build error in adalib I observe, that the content of a file created by the library make file contains incorrect path information: The line below should write the path to the sources of the ADA runtime library in to a file: $(VERBOSE)$(shell echo $(CONTRIB_DIR)/gcc-$(shell echo $(call _hash_of_port,gcc) | cut -d" " -f1)/src/noux-pkg/gcc/gcc/ada > $(ADA_RTS)/ada_source_path) when I inspect the created file it contains the following: /gcc-/src/noux-pkg/gcc/gcc/ada Some questions arise from this situation: 1) is it ideal to use the source in the contrib directory while building depots or should all source be copied in to the src package? and depending on the answer to the above question: 2) when using the source from contrib how to use the functions while building depots? 3) when copying all source in to the src package, how to handle the changes required to the make file for the library? best regards, Pirmin

Failure of Genode Demo
by zabarnyi＠campus.technion.ac.il 04 Jun '18

04 Jun '18

Hello, This is my first experience with Genode. I am trying to run a demo for Genode 17.05 (with toolchain 17.05, 64 bits), on an Oracle VM VirtualBox (5.2.10-122406) virtual machine, with Linux Ubuntu 16.04.4 (64 bits) OS. I am following the guide on https://genode.org/documentation/developer-resources/getting_started and I have already installed all the packages mentioned in this guide. However, when I try to run a demo using: cd build/x86_64 make KERNEL=linux run/demo the build of Genode succeeds, but the demo fails with the following error message: genode build completed using 'core-linux' as 'core' using 'ld-linux.lib.so' as 'ld.lib.so' using 'linux_timer_drv' as 'timer' spawn ./core Genode 17.05 17592186044415 MiB RAM and 8998 caps assigned to init Warning: blocking canceled in entrypoint constructor Error: Unexpected call of 'block_for_signal' (/genode/genode-17.05/repos/base/src/core/signal_receiver.cc:39) I would be grateful if you could help me to understand the reason for it (I couldn't find the answer on the web). Best regards, Konstantin

package dependencies
by Stefan Thöni 01 Jun '18

01 Jun '18

Hi, I ran into a problem when a genode package (pkg) was named both in parent pkg and it's child pkg like this: pkg/A/archives: _/pkg/B _/pkg/C pkg/B/archives: _/pkg/C pkg/C/archives: _/src/D When creating A, make complained of "recursive package dependency" but I'm sure there is no recursion. I then checked tool/depot/mk/dependencies.inc, 121L which yields that error and it looks to me as that code would always detect a paket named twiced in the dependency graph as recursive dependency. Is this intended? And if so, how should we deal with it?
