Notes:
Each package contains both DEBUG archived libraries and OPTIMIZED shared ones. By
default, the shared libraries are used when using the 'muesli-config' script (see
the Muesli User's Guide); the archived libraries can be used by specifying
the option '--libs-static' to the 'muesli-config' script.
It is always possible to compile your own main program with the '-g' flag in order
to use a debugger.
In both cases the installation of the package needs a lot of development version
of other packages.
Installation instructions:
For all Ubuntu versions mentioned above, you should be able to install the Muesli
package via a double-click on the debian archive, once downloaded; this will open
the 'Gnome Software' interface. Clicking to the 'install' button (if available)
should also install dependencies; note that you must have root access.
If you prefer using the command-line way, enter 'sudo dpkg -i muesli*.deb'
in a terminal.
If it complains about some missing package ('Error: dependencies problems'),
then enter the additional command: 'sudo apt install -f'.
Come back to the MUESLI home page.
