Pick a package which:
= Downloads =
* has very few dependencies
* is written in C or C++
* is part of Fedora @Core
 
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.
 
== Notes on packages built so far ==
 
<i>The list of packages in this section was constantly out of date, so I deleted it</i>
 
To see the packages which have been built so far, look in the git repo.  If you are planning to port another package, please ping us on <code>#fedora-riscv</code> first, just to make sure that two people don't do overlapping work.

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.

News

May 2024 We're starting a Special Interest Group! See the RISC-V SIG for more details.

May 2024 PLCT have releases a new repo for Fedora RV64 OCI image, currently F39 and F40 is avaliable. https://hub.docker.com/r/fedorariscv/base

Jun 2023 A new Fedora 38 OCI image for riscv64 is available.

May 2023 T-Head platform (Sipeed LicheePi 4A) description and installation how-to at Architectures/RISC-V/T-Head

Jan 2022 PLCT Lab have another new koji build system for Riscv64.

Oct 2021 Community member made a Fedora based BSP image for Allwinner D1 Nezha board. The information is available at Architectures/RISC-V/Allwinner. Note: Allwinner D1 is NOT officially supported by Fedora yet.

May 2018 A Koji build system instance is now building Fedora packages.

February/March 2018 Stage4 disk images are available. These are bootable in qemu and let you try out Fedora/RISC-V. Make sure you read the readme.txt file first. The development environment is quite complete with GCC 7.3.1, Perl 5.26, Python 2 and 3, git, systemd, various editors including vi and emacs, many -devel packages, and some X11 packages. It will be enough for most developers to start porting their software to RISC-V. The main missing things at the moment are Ruby, Java and Gtk 3.

Status January/February 2018 The third and hopefully final bootstrap of Fedora 27 has started. Please follow progress or try building it yourself via this git repository. Expected timelines are: 1-2 weeks until stage 3 disk images are available, 1-2 months until stage 4 pristine RPM-built disk images are available, 2 months until we are autobuilding regular Fedora packages, 3-6 months until we have koji-shadow functionality.
