silent rules: support for them is always active now Before this change, support for silent rules was optional and activated only if the 'silent-rules' option was specified. The rationale behind that behaviour was that the silent-rules machinery originally only worked with make implementations supporting nested variables expansions, which isn't (or wasn't) a POSIX-specified features; so that packages wanting to be "extra-portable" couldn't use the silent-rules machinery at all. But after Paul Eggert's commit 'v1.11-598-g8493499' of 25-12-2011, "silent-rules: fallback for makes without nested vars" (motivated by automake bugs #9928 and #10237), Makefiles generated when the 'silent-rules' option is enabled can work also with those make implementations that don't support nested variables expansion (albeit the configure-time selected verbosity cannot be overridden at make runtime in such case). In light of that, and since silent rules are disabled by default even when the 'silent-rules' option is given (unless the developer explicitly makes them enabled by default be calling "AM_SILENT_RULES([yes])" in configure.ac), we can now have the support for silent rules always enabled. The 'silent-rules' option will thus become a no-op, but will reaming a valid option for the time being, for better backward-compatibility. A collateral effect of this change is that the use of the 'silent-rules' option will not anymore automatically disable the warnings in the 'portability-recursive' category. The present change is basically a backport of the Automake-NG commit 'v1.11d-75-g61ca923' of 19-04-2012, "[ng] silent rules: support for them is always active now". Stemmed by this thread on the Automake-NG list: <http://lists.gnu.org/archive/html/automake-ng/2012-04/msg00027.html> * automake.in: Enable silent-rules machinery unconditionally. Reword some comments. Do not switch off warnings in the category 'portability-recursive' anymore if the 'silent-rules' option is given. * m4/init.m4: Call 'AC_REQUIRE' on 'AM_SILENT_RULES' unconditionally. * lib/Automake/Options.pm: Recognize 'silent-rules' as a dummy option. Do not bother anymore checking that it is set in 'configure.ac'. * t/silent.sh: Remove now-redundant calls to AM_SILENT_RULES. * t/silent2.sh: Likewise. * t/silent3.sh: Likewise. * t/silent4.sh: Likewise. * t/silent8.sh: Likewise. * t/silent9.sh: Likewise. * t/silent-lex.sh: Likewise. * t/silent-many-gcc.sh: Likewise. * t/silent-many-generic.sh: Likewise. * t/silent-yacc-headers.sh: Likewise. * t/silent-yacc.sh: Likewise. * t/silentcxx-gcc.sh: Likewise. * t/silentcxx.sh: Likewise. * t/silentf77.sh: Likewise. * t/silentf90.sh: Likewise. * t/help-silent.sh: Likewise. * t/silent-configsite.sh: Likewise, and other minor adjustments. * t/silent7.sh: Likewise. Also, extend to check that silent rules are disabled by default, and remove obsoleted checks about the 'silent-rules' option being rejected in 'AUTOMAKE_OPTIONS'. * t/silent6.sh: Remove now-redundant calls to 'AM_SILENT_RULES'. Call automake with '-Wno-portability-recursive'. Remove other obsoleted checks. * t/dollarvar.sh: Don't expect the use of 'AM_SILENT_RULES' in 'configure.ac' to disable warning in the 'portability-recursive' category anymore. * t/compile_f_c_cxx.sh: Adjust to avoid a spurious failure. * t/silent-amopts.sh: Remove as obsolete. * t/silent-nowarn.sh: Likewise. * t/list-of-tests.mk: Adjust. * NEWS: Update. * doc/automake.texi: Update and simplify accordingly. * configure.ac (AM_INIT_AUTOMAKE): Remove 'silent-rules' option.
