Version 7.1.0-1 is a new release; it follows the upstream QEMU release.

The xPack QEMU RISC-V is a standalone cross-platform binary distribution of QEMU.

There are separate binaries for Windows (x64), macOS (x64, arm64) and GNU/Linux (x64, arm64 and arm).

Download

The binary files are available from GitHub Releases.

Prerequisites

  • x64 GNU/Linux: any system with GLIBC 2.27 or higher (like Ubuntu 18 or later, Debian 10 or later, RedHat 8 or later, Fedora 29 or later, etc)
  • arm64/arm GNU/Linux: any system with GLIBC 2.27 or higher (like Raspberry Pi OS, Ubuntu 18 or later, Debian 10 or later, RedHat 8 or later, Fedora 29 or later, etc)
  • x64 Windows: Windows 7 with the Universal C Runtime (UCRT), Windows 8, Windows 10
  • x64 macOS: 10.13 or later
  • arm64 macOS: 11.6 or later

On GNU/Linux, QEMU requires the X11 libraries to be present. On Debian derived distribution they are already in the system; on RedHat & Arch derived distributions they must be installed explicitly.

Install

The full details of installing the xPack QEMU RISC-V on various platforms are presented in the separate Install page.

Easy install

The easiest way to install QEMU RISC-V is with xpm by using the binary xPack, available as @xpack-dev-tools/qemu-riscv from the npmjs.com registry.

With the xpm tool available, installing the latest version of the package and adding it as a dependency for a project is quite easy:

cd my-project
xpm init # Only at first use.

xpm install @xpack-dev-tools/qemu-riscv@latest

ls -l xpacks/.bin

To install this specific version, use:

xpm install @xpack-dev-tools/qemu-riscv@7.1.0-1.1

For xPacks aware tools, like the Eclipse Embedded C/C++ plug-ins, it is also possible to install QEMU RISC-V globally, in the user home folder.

xpm install --global @xpack-dev-tools/qemu-riscv@latest --verbose

Eclipse will automatically identify binaries installed with xpm and provide a convenient method to manage paths.

Uninstall

To remove the links from the current project:

cd my-project

xpm uninstall @xpack-dev-tools/qemu-riscv

To completely remove the package from the central xPacks store:

xpm uninstall --global @xpack-dev-tools/qemu-riscv

Compliance

The xPack QEMU RISC-V currently is based on the official QEMU, with no major changes.

The current version is based on:

  • QEMU version 7.1.0, commit 621da7789 from 30 August 2022.

Compared to the master qemu-system-riscv*, there are no major changes.

Shared libraries

On all platforms the packages are standalone, and expect only the standard runtime to be present on the host.

All dependencies that are build as shared libraries are copied locally in the libexec folder (or in the same folder as the executable for Windows).

DT_RPATH and LD_LIBRARY_PATH

On GNU/Linux the binaries are adjusted to use a relative path:

$ readelf -d library.so | grep runpath
 0x000000000000001d (RPATH)            Library rpath: [$ORIGIN]

In the GNU ld.so search strategy, the DT_RPATH has the highest priority, higher than LD_LIBRARY_PATH, so if this later one is set in the environment, it should not interfere with the xPack binaries.

Please note that previous versions, up to mid-2020, used DT_RUNPATH, which has a priority lower than LD_LIBRARY_PATH, and does not tolerate setting it in the environment.

@rpath and @loader_path

Similarly, on macOS, the binaries are adjusted with install_name_tool to use a relative path.

Documentation

The original documentation is available on-line:

Build

The binaries for all supported platforms (Windows, macOS and GNU/Linux) were built using the xPack Build Box (XBB), a set of build environments based on slightly older distributions, that should be compatible with most recent systems.

The scripts used to build this distribution are in:

  • distro-info/scripts

For the prerequisites and more details on the build procedure, please see the README-MAINTAINER page.

CI tests

Before publishing, a set of simple tests were performed on an exhaustive set of platforms. The results are available from:

Deprecation notices

32-bit support

Support for 32-bit x86 GNU/Linux and x86 Windows was dropped in 2022. Support for 32-bit Arm GNU/Linux (armv7l) will be preserved for a while, due to the large user base of 32-bit Raspberry Pi systems.

GNU/Linux minimum requirements

Support for RedHat 7 was dropped in 2022, and the minimum requirement was raised to GLIBC 2.27, available starting with Ubuntu 18 and RedHat 8.
