If you are running Debian GNU/Hurd in qemu, then you can use the "Debian" way to compile GNU Mach & the Hurd. I think that way is fairly easy-ish. And it makes it easy to apply the Debian specific patches, which you WILL WANT to do. https://www.gnu.org/software/hurd/contributing.html#index4h2 After you clone the repos, you can move into GNU Mach directory for instance. And apply the Debian specific patches. These are patches that mostly work, but are NOT quite polished enough via ... I forget the command it's something like COMMAND_NAME -a That applies all of the debian specific commands. Make your changes, then just running make will make GNU Mach. I think 'make install' should install your changed kernel. Ask in #hurd what is the command name to apply the Debian Specific patches. There are also Debian specific patches for the Hurd repo. > On Mon, Jun 16, 2025 at 2:41 AM Almudena Garcia <liberamenso10...@gmail.com > mailto:liberamenso10...@gmail.com > wrote: > > > > > Hi: > > > > To cross-compile gnumach from Linux you have to specify some flags in > > configure, to indicate the hurd architecture. > > > > You can find the flag list here: > > https://www.gnu.org/software/hurd/microkernel/mach/gnumach/building.html > > > > Read the instructions for non-Debian systems and 64-bit, and try again > > > > P.S.: I redirect this mail to bug-hurd, which is the main maillist now > > > > El lunes 16 de junio de 2025, Milos Nikic escribió: > > > Hello there, > > > > > > I am Milos, I am interested in writing code for Hurd. > > > I am developing inside qemu (on Arch linux) with debian > > > image debian-hurd-20230608.img. > > > It loads, boots and looks good!
