Thanks for the reply Bob. Well I indeed copy pasted from a Libtoolized project (by mistake) but first I noticed CFLAGS and CXXFLAGS where used when linking in a plain Automake project:
LINK = $(CCLD) $(AM_CFLAGS) $(CFLAGS) $(AM_LDFLAGS) $(LDFLAGS) -o $@ CXXLINK = $(CXXLD) $(AM_CXXFLAGS) $(CXXFLAGS) $(AM_LDFLAGS) $(LDFLAGS) -o $@ Also, as far as I can tell, Libtool filters flag only when linking shared libraries.
