Yes. With current Automake that will typically avoid exactly one line of output: | make -s all-am or: | make all-recursive (I guess you knew that you can set it at configure time as well by something like `AC_SUBST([AM_MAKEFLAGS], ["-s"])'. > I'm not sure how portable the -s flag is. It's POSIX. All `make' implementations I know have -s, which shuts them up more or less (e.g., GNU make still prints one line per makefile). > > except for that this only works starting from the second level 'make' > > invocation, and why does the patch silence the usual compile/link > > commands for programs and libraries but not for, say, texinfo output? > > There's no reason it couldn't be done for texinfos and other things also. > I wasn't sure if it would be useful, so I didn't add it. OK. > How likely is > it that the build command for texinfo stuff will exceed a line or two? Very likely if the command is generated by Automake and thus comes from automake/lib/am/texibuild.am. But I took this only as an example, there are other things Automake can build and I wanted to clarify whether your patch is merely partial or treating things differently on purpose (e.g., you only want to silence C/C++/F77 compilation and linking, but not any other build commands).
