Quick prototyping revealed that whether it is include_HEADERS or
otherwise does not really matter. Please see the code below:
(I must thank you and other automake maintainers for being able
to make it this simple.)
# AM_CHECK_HEADER(LIBRARY-NAME, MAKEFILE_AM)
# This is not compatible with AC_CHECK_HEADEER
AC_DEFUN(AM_CHECK_HEADER, [
# automake generates install rule if *include_HEADERS is defined
# in Makefile.am
if ! `grep include_HEADERS [$2] > /dev/null` ; then
AC_MSG_ERROR( *** No header files for lib[$1] *** )
fi
# There may be more than one rule
for HEADERS in `grep include_HEADERS [$2] | \
sed 's/include_HEADERS[ ]*=.*$/includeHEADERS/'`
do
# rule name is install-*includeHEADERS
install_lib[$1]_HEADERS="$install_lib[$1]_HEADERS \
install-$HEADERS"
done
])
If the headers do not need to be generated with BUILD_SOURCES, I
can simply call:
$(MAKE) -C $(libfoo_la_DIR) $(install_libfoo_HEADERS)
I still need to figure out how to trigger other rules that might
be involved in the BUILD_SOURCES cases.
I also realize that I really need to extend automake. Attaching
the rule like this and $(libfoo_la_HEADERS) to the dependency
list for foo is very redundant to what automake does on
Makefile.am for libfoo already.
