Solaris build instructions

The Solaris port of VirtualBox is work in progress and so is this page. The current page is just an edited version of the GNU/Linux one.


You need:

  • Solaris 11 is the recommended version for building VirtualBox.
  • GCC 3.4.3+ is recommended, obtain via Oracle's IPS/pkg(5) repository, see next item.
  • Install the following packages using:
    # pkg install SUNWgcc SUNWsvn SUNWhea FSWxorg-headers SUNWgnome-common-devel SUNWaudh SUNWusbu \
    SUNWugenu SUNWugen SUNWagph SUNWcurl SUNWxorg-mesa SUNWj6dev SUNWj6dvx header-math
  • libxml2. This ships with Solaris.
  • libxslt. This ships with Solaris.
  • Qt 4.7.4. You'll have to build this yourself.
    The source:

    Make sure QTDIR environment variable is pointing to the Qt installation and that the shared libraries can be found.
    Configure example (not the -I options for odd include locations):
    ./configure -v -platform solaris-g++-64 -thread -shared -stl -largefile -tablet -sm -disable-sql \
        -qt-imgfmt-jpeg -qt-imgfmt-png -qt-imgfmt-mng -qt-libjpeg -qt-libpng -qt-libmng -qt-zlib \
        -prefix /opt/vboxose-qt \
        -I/usr/include \
        -I/usr/X11/include \
        -I/usr/X11/share/include \
  • The PATH has to include the following directories:
    • /usr/sfw/bin - for gcc and related tools.
    • /usr/ccs/bin - for ar and other tools.
  • The LD_LIBRARY_PATH has to include the following directories:
    • /usr/sfw/lib - for gcc and related tools.
    • /usr/ccs/lib - for ar and other tools.

Building VirtualBox

  1. Change to the VirtualBox root directory of the sources and execute the configure script:
    `./configure --disable-hardening`

If it finds everything it needs, it will create a file called 'AutoConfig.kmk' containing paths to the various tools on your system. Also, it will create an environment setup script called This step only has to be done once (if something changes in your build tool setup, you might have to repeat it but keep in mind that both output files will be overwritten).

  1. Whenever you want to build VirtualBox, you have to open a shell and source the generated environment setup script '', i.e. do
    source ./
  1. To build a release package, type
    kmk all
    This produces the required binaries in out/solaris.x86/release/bin/. If you want to build a debug version, type:
    kmk BUILD_TYPE=debug
  1. If you made a hardened build (that is, you omitted the --disable-hardened switch from configure) you have to set some symbolic links manually to be able to start VMs from the bin/ directory:
cd out/solaris.amd64/release/bin/components
ln -s ../ .
ln -s ../ .
ln -s ../ .
ln -s ../ .
ln -s ../ .

Running your build

You can run VirtualBox directly from the build target directory (out/solaris.x86/release/bin/). But first of all, you must install the VirtualBox kernel module. There is a script src/VBox/HostDrivers/Support/solaris/ which does this for you. It requires you to either install sudo or run it as root.

Or, you can do the following:

cd out/solaris.amd64/release/bin

You will need to copy the driver file and .conf file (if any), everytime they change, into the appropriate locations. Currently the drivers are vboxdrv (the primary host driver), vboxflt (bridged & host-only network filter), vboxnet (host-only network adapter), vboxusbmon (USB monitor), vboxusb (USB client).

/platform/i86pc/kernel/drv/       (32-bit drivers and .conf files)
/platform/i86pc/kernel/drv/amd64  (64-bit drivers)

And then run as root/sudo: --setupdrivers

The vboxconfig script only (re)loads drivers that are found in the appropriate locations (don't forget to copy the ".conf" files).

If you made a hardened build, make sure that the setuid stubs have the correct permissions:

for f in VirtualBox VBoxHeadless VBoxSDL VBoxBFE VBoxNetDHCP VBoxNetAdpCtl; do
  chown root:bin $f
  chmod 4511 $f

Finally, you can start one of the frontends, e.g.
