Hi Werner et al.!
*If* we bundle guile 1.8 with lilypond, I strongly prefer static
linking of the library (this is, adding `--disable-shared' to guile's
configure script, together with a proper argument to the
`--datarootdir' option to install the .scm files under a lilypond
directory). This avoids *any* problems with different guile library
versions, and the created lilypond binary can peacefully coexist with
guile 2.0 even in the `/usr' tree.
After a loser look at the sources and the build system I think it's better
(= much easier) to stay with shared libraries.
At runtime we do need both libguile and guile itself (it is used by
lilypond-invoke-editor), and all of our guile must be invisible to the
rest of the system.
That means:
+ there must be no entry in PATH leading to our private guile, guile-config etc.
+ there must be no entry leading to libguile etc in the system library search
path.
All that is possible without major changes to the sources... attached find a
bash
script as a proof of concept. The requirements described above are met.
It passes the "full make" test without problems:
