I would expect aclocal to fail and terminate the build script if warnings
appear [1]; however, it does not happen:
== Steps to reproduce ==
{ cat >configure.ac <<'#>configure.ac' && aclocal -W error && echo $?; }
AC_INIT([name],[0.0.1])
AC_CANONICAL_TARGET
AM_INIT_AUTOMAKE
AC_COMPILE_IFELSE()
AC_USE_SYSTEM_EXTENSIONS
#>configure.ac
== Actual results ==
configure.ac:26: warning: AC_COMPILE_IFELSE was called before
AC_USE_SYSTEM_EXTENSIONS
0
== Expected results ==
configure.ac:26: warning: AC_COMPILE_IFELSE was called before
AC_USE_SYSTEM_EXTENSIONS
== Workaround ==
{ WARNINGS=error aclocal; }
aclocal: autom4te failed with exit status: 1
== Remarks ==
It seems that aclocal fails to pass -Werror to autom4te.
