So the .am file is like this:
.POSIX:
SUFFIXES = .pc
.pc.lo:
cp $*.pc $*.c
$(LIBTOOL) --tag=CC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) --mode=compile
$(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS)
$(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS) -c -o $@ $*.c
rm -f $*.c
CCLD = $(CC)
LINK = $(LIBTOOL) --tag=CC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) \
--mode=link $(CCLD) $(AM_CFLAGS) $(CFLAGS) $(AM_LDFLAGS) \
$(LDFLAGS) -o $@
noinst_LTLIBRARIES=libfoo.la
libfoo_la_SOURCES=foo.pc bar.c
The libfoo_la_SOURCES are not added to the tags list and the tags
goals are not generated:
excerpt from the Makefile.in
---------
tags: TAGS
TAGS:
ctags: CTAGS
CTAGS:
---------
Adding them to the TAGS_FILES explicitly (as Stefano had advised)
doesn't help. It seems that it's being overridden.
