Automake 1.11 introduced the concept of "silent build rules" wherein the build commands are reported as CC spu_explicit.lo rather than something along the lines of /bin/bash ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I../../../../../opmtransport/src -I.. -O3 -DNDEBUG -Wall -Wextra -std=c99 -pedantic -march=native -mtune=native -MT spu_explicit.lo -MD -MP -MF .deps/spu_explicit.Tpo -c -o spu_explicit.lo ../../../../../opmtransport/src/spu_explicit.c libtool: compile: gcc -DHAVE_CONFIG_H -I. -I../../../../../opmtransport/src -I.. -O3 -DNDEBUG -Wall -Wextra -std=c99 -pedantic -march=native -mtune=native -MT spu_explicit.lo -MD -MP -MF .deps/spu_explicit.Tpo -c ../../../../../opmtransport/src/spu_explicit.c -fPIC -DPIC -o .libs/spu_explicit.o libtool: compile: gcc -DHAVE_CONFIG_H -I. -I../../../../../opmtransport/src -I.. -O3 -DNDEBUG -Wall -Wextra -std=c99 -pedantic -march=native -mtune=native -MT spu_explicit.lo -MD -MP -MF .deps/spu_explicit.Tpo -c ../../../../../opmtransport/src/spu_explicit.c -o spu_explicit.o >/dev/null 2>&1 The former is much easier to read and, consequently, more conducive to visually noticing diagnostics from the toolset (compiler, linker &c). On the other hand, only fairly recent editions of Automake have the "silent rule" capability, so enable silent rules only if available. In particular, Automake 1.10.x (the default Automake version in MacOS X 10.6) does not support the capability. Neither does the default Automake in CentOS 5.6. Further details on silent build rules can be found at http://sources.redhat.com/automake/automake.html#Options http://www.flameeyes.eu/autotools-mythbuster/automake/silent.html Thanks to Arne Morten Kvarving in Dune Flyspray issue #922 (http://www.dune-project.org/flyspray/index.php?do=details&task_id=922) for the tip on how to preserve "configure.ac" backwards compatibility with Automake < 1.11 .
