AC_CONFIG_FILES and AC_CONFIG_HEADERS both handle inputs files
in the build tree. (For instance on output of AC_CONFIG_FILES can
be used as input for another AC_CONFIG_FILES.)
The code for _AC_OUTPUT_FILES and AC__OUTPUT_HEADERS have
a section with
# First look for the input files in the build tree, otherwise in the
# src tree.
However this is not the case of AC_CONFIG_LINKS. I've just
discovered this while writing a test case for Automake.
_AC_OUTPUT_SUBDIRS expects the source of a link to be in the
source tree.
if test ! -r $srcdir/$ac_source; then
AC_MSG_ERROR([$srcdir/$ac_source: file not found])
fi
I wonder if this is deliberate or if this is just an oversight.
This looks bogus to me. For instance I think it would make
sense to output several config files with AC_CONFIG_FILES, and
then make a link to one of them with AC_CONFIG_LINKS.
