Обсуждение: `make depend' broken in CVS sources

`make depend' is broken in the CVS sources.  I've only tested it when
using a build directory which is different from the source directory,
but frankly it looks broken anyhow.

This is what I get:

make -C backend depend
make[1]: Entering directory `/home/ian/pgsql-objdir/src/backend'
for i in access bootstrap catalog parser commands executor lib libpq main nodes optimizer port postmaster regex rewrite
storagetcop utils; do make -C $i depend; done

gcc: *.c: No such file or directory

etc.

Making this change to src/backend/access/common/Makefile fixes the
first error:

I can submit a patch to make a similar change to all Makefiles.
Before I do, is `make depend' still supported?  Is there a better way?

'make depend' doesn't exist anymore.  Use configure --enable-depend.

However, the makefiles are still full of depend targets --- so someone
who hadn't read the configure docs with eagle eyes could be forgiven
for thinking that 'make depend' will do what it usually does in most
other project trees.

Perhaps in the next release the make targets should be renamed to
something other than depend.  At the very least, it'd be nice if
'make depend' at the top level would emit a helpful error message
rather than doing something obscure/wrong.
