I see the same thing. But when I do make -j3 at the toplevel, it bombs out as described before. > I *can* reproduce failures if I do the same thing one directory level > up, in src/interfaces/ecpg.

I think this one does not occur on a fresh build because ecpg_config.h is created by configure and is only removed by make maintainer-clean. If I make maintainer-clean in src/interfaces/ecpg, then rerun config.status, and then do make -j it succeeds. However, if I repeat those steps from one level further up, in src/interfaces, then it bombs out as described in my OP. > This is with make-3.82-3.fc14.x86_64 ... That's the same make I'm using here. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
