Building PostgreSQL outside the source tree is slightly broken:
(Using the current CVS HEAD code)
$ mkdir ~/test-pg-build
$ cd ~/test-pg-build
$ ../pgsql/configure
[ output omitted]
$ make
[ output omitted; make succeeds ]
$ touch ../pgsql/configure # i.e. cvs up
$ make
The final make command invokes 'config.status --recheck', which
invokes '../pgsql/configure --no-create --no-recursion'. The re-run of
configure succeeds, but the rest of the make fails abruptly:
make: *** No rule to make target `src/Makefile.global.in', needed by
`src/Makefile.global'. Stop.
When 'configure' has been updated, we use config.status to re-run
configure with the arguments that were previously specified. The
problem is caused by the '--no-create' flag passed to configure by
config.status: in configure.in we don't set the 'vpath_build' variable
if '--no-create' has been specified.
(Therefore, when src/Makefile.global is recreated after configure is
re-run, the 'vpath_build' variable isn't set, and a vpath build
(i.e. a build outside the source tree) obviously fails.)
Any comments on how we should fix this?
