Building for Linux

Disclaimer: Support for Linux is experimental.

Prerequisites

  • Linux headers
  • NASM 2.11 or later

Build steps

  1. cd platforms/linux/
  2. make

Testing on Linux

System requirements

Note that these are requirements for the test environment, which does not have to be the same as the build environment.

  1. Hardware requirements are the same as those for Windows.
  2. Linux 4.x or later.

Loading and unloading the kernel module

To load the kernel module:

  1. Make sure no other HAXM kernel module is loaded. If the output of lsmod | grep haxm is not empty, you must unload the existing HAXM module first: sudo make uninstall.
  2. Run sudo make install.

To unload the kernel module:

  1. Run sudo make uninstall.

Additionally, if you want to use HAXM as a non-privileged user, you can enter the following command to make the current user part of the haxm group (requires logging out and back in!):

sudo adduser `id -un` haxm

Note that in recent Linux distributions, you might get a sign-file error since it kernel Makefiles will attempt to sign the kernel module with certs/signing_key.pem. Unless driver signature enforcement has been enabled, you can safely ignore this warning. Alternatively, you can follow this guide to self-sign your drivers.

Viewing logs

On Linux, HAXM debug output goes to the system log database, and can be retrieved via dmesg (if supported, the -w flag will update the output). You might filter these entries via: dmesg | grep haxm.
