EESSI RISC-V development repository (dev.eessi.io/riscv)¶
Is dev.eessi.io a webpage?
If you landed on this page because you typed dev.eessi.io into your browser, then
you may not know yet that this is not a URL/webpage but a CernVM-FS repository
that EESSI uses to distribute software.
See the EESSI overview page for a general introduction to EESSI.
This repository contains development versions of an EESSI RISC-V software stack
and replaces the older riscv.eessi.io repository, which is now deprecated.
Note that versions may be added, modified, or deleted at any time.
Accessing the RISC-V repository¶
See Getting access;
by making the EESSI CVMFS domain available, you will automatically have access to dev.eessi.io/riscv as well.
Using dev.eessi.io/riscv¶
This repository currently offers one version (2025.06-001), which is built on top of the
RISC-V compatibility layer of EESSI version 2025.06 in the production repository software.eessi.io.
New versions may be added later, and will be named similarly.
You can use this version by running the following commands on a RISC-V machine:
$ export EESSI_VERSION_OVERRIDE=2025.06-001
$ source /cvmfs/software.eessi.io/versions/2025.06/init/lmod/bash
This EESSI production version only provides a RISC-V compatibility layer,
software installations are provided by the EESSI development repository at /cvmfs/dev.eessi.io/riscv.
Module for EESSI/2025.06 loaded successfully
EESSI has selected riscv64/generic as the compatible CPU target for EESSI/2025.06
EESSI did not identify an accelerator on the system
(for debug information when loading the EESSI module, set the environment variable EESSI_MODULE_DEBUG_INIT)
Note that we currently only provide generic builds, hence riscv64/generic is being used for all RISC-V CPUs.
We are currently working on support for builds that are optimized for specific RISC-V CPUs.
The amount of software is constantly increasing.
Besides having the foss/2025a and foss/2025b toolchains available, several applications are already available as well.
