I eventually succeded in installing 1.2.0 from sources on my debian
system.
Here is some information on the problems encountered and their solution:
1) configure complains that it cannot find guile-config.
Cure: Install the libguile4-dev package.
2) Configure complains that guile should be newer than 1.3 even if
libguile version is 1.3.15; this is just a warning but it is probably
related to problem 3.
3) Link reports some undefined references:
Cure:
As suggested by Ian Stirling, after running configure, config.make has
to be modified adding
-lguile -lqthreads to the definition of EXTRA_LIBES.
4) dvips and xdvi are not able to find the feta*.mf files:
Cure:
Insert
MFINPUTS=:/usr/local/share/lilypond/mf
export MFINPUTS
in .profile.
5) LaTeX is not able to find the feta*.tfm files.
Cure: Not yet solved really, a workaround is to copy the files needed
to the working directory.
Hope this can be of some help to other Debian users, if you have a
suggestion to solve problem 5) please let me know.
Ciao,
