Status: The stage3 disk image boots to a shell, with GCC, numerous developer utilities, and rpmbuild.

* has very few dependencies

Grab the source RPM from [http://koji.fedoraproject.org/koji/ Koji].
 
Copy the source RPM into the stage3 disk image.  The disk image <b>must not</b> be running when you do this:
 
virt-copy-in -a stage3-disk.img the_package.src.rpm /var/tmp/
 
Boot the disk image in qemu:
 
make boot-stage3-in-qemu
 
Inside the VM you can now "install" the source RPM, which makes it available under <code>/rpmbuild</code>:
 
rpm -i /var/tmp/the_package.src.rpm
cd /rpmbuild/SPECS
 
You may need to disable hardened build by adding:
 
%undefine _hardened_build
 
to the spec file.  Use <code>vim</code> to edit files.
 
You can now try building the package:
 
rpmbuild -ba the_package.spec --define "debug_package %{nil}"
 
If it builds successfully, brilliant!  More usually this will require many cycles of debugging and fixing things.  Removing dependencies or parts of the spec file is an option for these stage3 builds.
 
If you get a build, it will be in <code>/rpmbuild</code> inside the VM.  sync and shut down the VM, then do:
 
virt-copy-out -a stage3-disk.img /rpmbuild ./
 
and the files will be downloaded to ./SRPMS and ./RPMS in the current directory.  Note: Keep the source RPM too, especially if you modified it.
 
Add notes to the section below.  Also come to <code>#fedora-riscv</code> and discuss where to put your built packages.

RISC-V (pronounced "RISC Five") is an open source instruction set architecture (ISA). This project, informally called Fedora/RISC-V, aims to provide a complete Fedora experience on the RISC-V (64 bit, RV64GC) architecture.

Topics

  • Installing - How to download, install and run Fedora/RISC-V.
  • Hardware - Information about supported and experimental Fedora/RISC-V hardware

Outdated information

Over time, we have accumulated lots of information on this wiki. A large chunk of it, while useful at the time, is not really relevant to anyone looking to run Fedora on RISC-V today, or contribute to the porting effort. To avoid any confusion, all outdated material has been moved to the Archive.
