(BTW, you have to remove the postgres executable, else make won't even try to rebuild it.) IMO this is broken. It did not use to work like that, either. I'm familiar with the behavior here because I frequently recompile individual .o files (eg, to build them with nondefault -O settings) and am in the habit of rm'ing the .o file afterwards to let things go back to normal. They no longer do. Having seen this, I now think .SECONDARY is broken across the board. A case comparable to .o files with nondefault CFLAGS could be that one manually edits gram.c (say, to inject some debugging code), rebuilds, and later wants to revert to a standard build. Formerly you'd just rm gram.c and things would be good. Now, it's quite unobvious what would need to be removed to convince make to do what it's contracted to do. If you didn't watch the rebuild step very closely (or, heaven forbid, used make -s and didn't see anything), you could waste a lot of time before realizing that make hadn't done what it's supposed to. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
