1.1 Installation

mu-guile is part of mu - by installing the latter, the former is necessarily installed as well. At the time of writing, there are no distribution-provided packaged versions of mu-guile; so for now, you need to follow the steps below.

1.1.1 Guile 2.x

mu-guile is built automatically when mu is built, if you have guile version 2 or higher. (mu checks for this during configure). Thus, the first step is to ensure you have guile installed.

On Debian/Ubuntu you can install guile 2.x using the guile-2.0-dev package (and its dependencies):

$ sudo apt-get install guile-2.0-dev

At the time of writing, there are no official packages for Fedora¹. If you are using Fedora or any other system that does not have packages, you need to compile guile from source².

1.1.2 gnuplot

For creating graphs with mu-guile, you need the gnuplot program – most likely, there is a package available for your system; for example:

$ sudo apt-get install gnuplot

and in Fedora:

$ sudo yum install gnuplot

1.1.3 mu

Assuming guile 2.x is installed correctly, mu finds it during its configure-stage, and creates mu-guile. Building mu follows the normal steps – please see the mu documentation for the details.

The output of ./configure should end with a little text describing the detected versions of various libraries mu depends on. In particular, it should mention the guile version, e.g.

Guile version                        : 2.0.3.82-a2c66

If you don’t see any line referring to guile, please install it, and run configure again. After a succesfull ./configure, we can make and install the package:

$ make && sudo make install

1.1.4 mu-guile

After this, mu and mu-guile are installed – usually somewhere under /usr/local.You may need to update guile’s %load-path to find it there. You can check the current %load-path with the following:

guile -c '(display %load-path)(newline)'

If necessary, you can add the %load-path by adding to your ~/.guile:

(set! %load-path (cons "/usr/local/share/guile/site/2.0" %load-path))

Or, alternatively, you can set GUILE_LOAD_PATH:

export GUILE_LOAD_PATH="/usr/local/share/guile/site/2.0"

In both cases the directory should be the directory that contains the installed mu.scm; if you installed mu under a different prefix, you must change the %load-path accordingly. After this, you should be ready to go!
