I was looking for ways to reduce the noise in Postgres make output, specifically, I wanted to eliminate the "Nothing to be done for `all' " messages, since they don't add much value, and just ad to the clutter.
Most of the solutions I have seen propose grepping out the noisy parts. But one of them proposed adding a .PHONY rule and then adding a no-op command to a target's recipe. Attached is a small patch to a few makefiles which helps remove the above mentioned message. Following is a sample output: ... make[3]: Entering directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/bin/initdb' make -C ../../../src/port all make[4]: Entering directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/port' make -C ../backend submake-errcodes make[5]: Entering directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/backend' make[5]: Leaving directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/backend' make[4]: Leaving directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/port' make -C ../../../src/common all make[4]: Entering directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/common' make -C ../backend submake-errcodes make[5]: Entering directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/backend' make[5]: Leaving directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/backend' make[4]: Leaving directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/common' make[3]: Leaving directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/bin/initdb' make[2]: Leaving directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/bin' make -C pl all make[2]: Entering directory `/home/gurjeet/dev/pgdbuilds/quiet_make/src/pl' ... The noise can be further reduced by adding the --no-print-directory switch, which yeilds the following output: ... make -C ../backend submake-errcodes make -C psql all make -C ../../../src/interfaces/libpq all make -C ../../../src/port all make -C ../backend submake-errcodes make -C ../../../src/common all make -C ../backend submake-errcodes make -C scripts all make -C ../../../src/interfaces/libpq all make -C ../../../src/port all ... The only downside I see to this patch is that it emits this warning in the beginning: GNUmakefile:14: warning: overriding commands for target `all' src/Makefile.global:29: warning: ignoring old commands for target `all' This is from the recipe that emits the message "All of PostgreSQL successfully made. Ready to install." For really quiet builds one can use the -s switch, but for someone who wishes to see some kind of progress and also want a cleaner terminal output, the --no-print-directory switch alone is not enough.
