MirAL
|
These instructions assume that you’re using Ubuntu 16.04LTS or later, I’ve not earlier Ubuntu versions or other distributions.
You’ll need a few development and utility packages installed, along with the Mir graphics drivers:
$ sudo apt-get install devscripts equivs bzr $ sudo apt-get install mir-graphics-drivers-desktop
(If you’re working on a phone or tablet use mir-graphics-drivers-android in place of mir-graphics-drivers-desktop.)
With these installed you can checkout and build miral:
$ bzr branch lp:miral $ sudo mk-build-deps -i --build-dep miral/debian/control $ mkdir miral/build $ cd miral/build $ cmake .. $ make
This creates libmiral.so in the lib directory and an example shell (miral-shell) in the bin directory. This can be run directly:
$ bin/miral-shell
With the default options this runs in a window on X (which is convenient for development).
The miral-shell example is simple, don’t expect to see a sophisticated launcher by default. You can start mir apps from the command-line. For example:
$ bin/miral-run gnome-terminal
That’s right, a lot of standard GTK+ applications will “just work” (the GDK toolkit has a Mir backend). Any that assume the existence of an X11 and bypass the toolkit my making X11 protocol calls will have problems though.
To exit from miral-shell press Ctrl-Alt-BkSp.
To run independently of X11 you need to grant access to the graphics hardware (by running as root) and specify a VT to run in. For example:
$ sudo bin/miral-shell --vt 4 --arw-file --file $XDG_RUNTIME_DIR/mir_socket
For convenient testing there's a "miral-desktop" script that wraps this command to start the server (as root) and then launches the gnome-terminal (as the current user):
$ bin/miral-desktop -bindir bin
If you want to run X11 applications that do not have native Mir support in the toolkit they use then the answer is Xmir: an X11 server that runs on Mir. First you need Xmir installed:
$ sudo apt install xmir
Then once you have started miral-shell (as above) you can use miral-xrun to run applications under Xmir:
$ bin/miral-xrun firefox
This automatically starts a Xmir X11 server on a new $DISPLAY for the application to use. You can use miral-xrun both from a command-line outside the miral-shell or, for example, from a terminal running in the shell.
Assuming you have a Mir server running, native Mir applications can be started from the command-line:
$ sudo apt-get install mir-demos $ mir_demo_client_egltriangle
Similarly, GTK+, Qt and SDL applications can be run with the miral-run script:
$ bin/miral-run gedit $ bin/miral-run 7kaa
You can list the configuration options for miral-shell with "--help":
$ bin/miral-shell --help
Most of these options are inherited from Mir. These can be set on the command line, by environment variables or in a config file. For example, if you want to start the gnome-terminal when you run miral-shell you can:
Set supply the option on the command line:
$ bin/miral-shell --startup-apps gnome-terminal
Set the corresponding MIR_SERVER_<option> environment variable:
$ export MIR_SERVER_STARTUP_APPS=gnome-terminal ... $ bin/miral-shell
Create a miral-shell config file:
$ echo startup-apps=gnome-terminal > ~/.config/miral-shell.config ... $ bin/miral-shell
To run Qt applications under Mir you may need to install qtubuntu-desktop:
$ sudo apt-get install qtubuntu-desktop
MirAL comes with a set of tests, if you intend to build these then add the following packages:
$ sudo apt-get install cmake-extras google-mock mirtest-dev mir-test-tools $ sudo apt-get install libboost-filesystem-dev libboost-system-dev
Note that this is not possible for Mir versions prior to 0.24 as there were bugs in mirtest-dev. At the time of writing Ubuntu 16.4 has Mir-0.21.
