Your point about apps needing to link with the srfi libs is one I had
not considered. If they link at compile time, then one either has
them in a default path, uses LD_LIBRARY_PATH, or uses -rpath/-R (or
loses). This is exactly the situation for libguile today.
another option is to provide "guile-config link-internal". e.g.:
$ guile-config link
-L/home/ttn/local/lib -lguile -lltdl -lm
$ guile-config link-internal
guileqthreads
guilereadline
guilesrfi_13_14
guilesrfi_4
$ guile-config link-internal guilesrfi_13_14
-L/home/ttn/local/lib/guile/1.4.1.89/modules -lguilesrfi_13_14
this way, the large majority of people who don't care about these
internal libraries can remain blissfully unaware of them, but yet the
necessary info is available to those who have the need. their makefiles
would look like:
LIBS = `guile-config link` `guile-config link-internal guilesrfi_13_14`
problem solved, everybody's happy. in fact, i like this idea so much,
see below for a diff against scripts/guile-config that implements this
in cvs (will appear in 1.4.1.90).
