Question: rebuilding frontend tools after libpgfeutils.a changes?
Hi,
While working on patch [1]/messages/by-id/0594CC79-1544-45DD-8AA4-26270DE777A7@gmail.com, I noticed that after modifying astreamer_lz4.c, running “make" only rebuilds libpgfeutils.a, but does not automatically rebuild the client tools that depend on it. This makes iterative development a bit inconvenient, as the tools need to be rebuilt manually.
I am wondering whether it would be worth updating the relevant Makefiles so that changes to libpgfeutils.a properly trigger rebuilds of dependent frontend binaries.
Since this would likely involve touching quite a few Makefiles, I’d prefer to check first whether committers think the effort is worthwhile before spending time on it. That’s the reason for this email.

I'd vote no, because it would add a lot of usually-pointless cycles to
normal rebuild cases.
Now, I'm a guy who doesn't believe in --enable-depend either, so
your opinion might differ. But it would not be a free improvement.

Thanks for the guidance. I will not spend time on that then.
