I think this was discussed before, but i'm not sure how to downgrade guile on Ubuntu 18.04.2 LTS
I tried building guile-1.8.0, guile-1.8.4, guile-1.8.5, but the build fails for all three.
lilypond ./configure error:
ERROR: Please install required programs: guile-config < 1.9.0 (installed: 2.2.3) (guile-devel, guile-dev or libguile-dev package) libguile (libguile-dev, guile-devel or guile-dev package). GUILE-with-rational-bugfix
You likely need to point configure to guile and guile-config
../configure GUILE_CONFIG=/path/to/guile-config GUILE=/path/to/guile
i don't follow the above. You would point to /path/to/guile-config and /path/to/guile
if you have the right version installed. Lilypond is complaining that my installed version is too new.
Or -- correct me if i'm wrong -- as an alternative to downgrading, I could build an old, compatible version from source, to an isolated directory, and satisfy the lilypond dependency that way?
I was asking about the latter: the older versions of guile are not compiling.
