xPack QEMU RISC-V v7.2.0-1 released
The xPack QEMU RISC-V is a standalone cross-platform binary distribution of QEMU.
There are separate binaries for Windows (Intel 64-bit), macOS (Intel 64-bit, Apple Silicon 64-bit) and GNU/Linux (Intel 64-bit, Arm 32/64-bit).
Download
The binary files are available from GitHub Releases.
Prerequisites
- GNU/Linux Intel 64-bit: 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)
- GNU/Linux Arm 32/64-bit: 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)
- Intel Windows 64-bit: Windows 7 with the Universal C Runtime (UCRT), Windows 8, Windows 10
- macOS Intel 64-bit: 10.13 or later
- macOS Apple Silicon 64-bit: 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@7.2.0-1.1
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 created by xpm in 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 major changes.
The current version is based on:
- QEMU version 7.2.0, commit b67b00e from Dec 13, 2022.

Known problems
- in order to build on macOS 10.13, the Intel macOS version has some functionality related to bridged virtual interfaces disabled.
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:
Tests

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