the Raven libraries generally work fine on the R6RS implatetion, except for some built on the c library which dependent on Chez Scheme's FFI.
Running project:
$ raven run exemple.sc
if you will run a project compiled:
$ export CHEZSCHEMELIBDIRS=.:lib:/usr/local/lib
$ export CHEZSCHEMELIBEXTS=.chezscheme.sls::.chezscheme.so:.ss::.so:.sls::.so:.scm::.so:.sch::.so:.sc::.so
$ scheme exemple.so
The project Raven is supported by theschemer.org
The principal developers are: guenchi, chclock
Nota Bene: We recommend that the libraries for Raven files use .sc for distinguishing the libraries of r5rs / r7rs small.
