QEMU builder helper repository

This repository helps in building QEMU and its dependencies. The Kalray KVX port makes use of a Kalray specific dependency called LAO. A simple Makefile is provided to perform the necessary steps for you.

Requirements

Some dependencies must be installed on your system for QEMU to build. Also ninja is recommended to build QEMU but make can be used as well. The LAO library uses the CMake build system. On a Debian/Ubuntu-like system, you can install the following packages:

apt install git libglib2.0-dev libfdt-dev libpixman-1-dev zlib1g-dev ninja cmake

Customizing the installation

By default, QEMU will be installed in a local prefix (./prefix) in this repository. You can change that by giving another prefix to the make command (see bellow) or by editing the Makefile (e.g., if you wish to install it to /usr/local).

Building QEMU

Start by initializing the two submodules

$ git submodule update --init

Then simply run make.

$ make -j$(($(nproc) + 1))

To specify another installation prefix:

$ make -j$(($(nproc) + 1)) PREFIX=/some/path

At the end, you should have a qemu-system-kvx symbolic link pointing to the QEMU executable in the prefix QEMU was installed in.
