Building Rust projects with a custom profile
Starting with Rust 1.77, our Rust Goa projects were giving us trouble. My colleague Sebastian was quick to figure out and fix the initial runtime linking problem. However, with that out of the way, the applications would simply crash with a segfault. Continue...

Goa - Using a headless Sculpt as a remote test target
Goa's ability to run applications on a remote Sculpt system comes in handy for testing. However, switching between keyboards to control the remote-running application is a tiny inconvenience. My recent experiments with Sculpt on a ZimaBlade, which has no built-in display, thus motivated me to experiment with solutions for Sculpt as a truly remote test target. Continue...

Manually installing wsman(1)
For convenience and to some degree also necessity most of our x86-based test machines feature AMT to power-cycle the system and also gain serial console access via SOL. On recent systems the controlling part is done via WS-MAN, for which a package is not always readily available on Linux distributions. The following post gives short instructions on how to build it manually and illustrates one or the other pitfall. Continue...

Sculpt Customisation
The modularisation of Sculpt with release 22.02 enabled us to easily build customised Sculpt images. Instead of personalising my Sculpt OS via config files on the used file system, I've been managing my customisations in a separate repository since then. In this article, I want to share what modifications have worked out for me and provide ideas to fellow Genodians. Continue...

Enabling the upstream Rust toolchain
Release 23.05 reintroduced support for the Rust programming language to Genode, but our initial implementation relied on a slightly adapted Rust toolchain. As detailed in my previous blog post, we were working around issues with versioned FreeBSD libc symbols that were unsupported by our linker. Continue...
