Let's say your init function is named scm_init_postgres. Then write a new function: void scm_init_postgres_gpostgres_module () { scm_register_module_xxx ("postgres gpostgres", scm_init_postgres); } Compile everything into a shared library (libgpostgres.so) and install. Put links from /usr/local/share/guile/postgres/libgpostgres.la and /usr/local/share/guile/postgres/libgpostgres.so.1 to /usr/local/lib/libgpostgres.la and /usr/local/lib/libgpostgres.so.1. (Of course you may have to replace /usr/local with some other prefix.) Then you should be able to load the object code with (use-modules (postgres gpostgres)) If you have scheme code as well you could put it into /usr/local/share/guile/postgres/postgres.scm and start the file with (define-module (postgres postgres) :use-module (postgres gpostgres)) /mdj
