I don't think so. I checked it out (still on pgfoundry, still on CVS, and code hasn't been touched since 2008), and run into some issues. - It looks for libguile.h #include "libguile.h" which, on 2.0, has shifted around from /usr/include/libguile.h (1.8) to /usr/include/guile/2.0/libguile.h It's not doing enough indirections internally; there is a guile-config that is analogous to pg_config postgres@cbbrowne [03:48:43] [~/PostgreSQL/plscheme] -> % guile-config compile -pthread -I/usr/include/guile/2.0 postgres@cbbrowne [03:48:45] [~/PostgreSQL/plscheme] -> % guile-config link -lguile-2.0 -lgc It looks like there's something PG-related as a next issue: -> % ./install.sh pg_config : /var/lib/postgresql/dbs/postgresql-HEAD/bin/pg_config module-dir : /var/lib/postgresql/dbs/postgresql-HEAD/lib max-cache-size: 64 dbname : postgres safe-r5rs : NO dbacreate : NO PSQL : /var/lib/postgresql/dbs/postgresql-HEAD/bin/psql postgres CPPFLAGS : -g -Wall -fpic -c -I/var/lib/postgresql/dbs/postgresql-HEAD/include/server -I/usr/include/guile/2.0 LDFLAGS : -shared -lguile Compiling... failed! plscheme.c: In function '_PG_init': plscheme.c:647:2: warning: implicit declaration of function 'DefineCustomStringVariable' [-Wimplicit-function-declaration] plscheme.c:650:30: error: 'PGC_BACKEND' undeclared (first use in this function) plscheme.c:650:30: note: each undeclared identifier is reported only once for each function it appears in plscheme.c:652:2: warning: implicit declaration of function 'DefineCustomIntVariable' [-Wimplicit-function-declaration] plscheme.c: In function 'plscheme_func_handler': plscheme.c:742:2: warning: implicit declaration of function 'GetTopTransactionId' [-Wimplicit-function-declaration] plscheme.c: In function 'parse_trig_args': plscheme.c:1623:44: error: dereferencing pointer to incomplete type plscheme.c:1628:38: error: dereferencing pointer to incomplete type ... (See error.log for details.) I'm not sure to what degree this is bitrot relating to: a) Postgres changes b) Guile changes but there's doubtless a bit of both. I'd think it interesting to get this back to working order, whether it's useful for JavaScript or not. -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?" -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
