Hi,
Sometimes it is useful to distinguish C from C++ preprocessed
files, I use .ii for C++ and .i for C. If you want to retain the
CFLAGS/CXXFLAGS/CPPFLAGS from configure, then it's convenient to define
the rule as:
SUFFIXES += .i .ii
.c.i:
$(COMPILE) -E $< > $@
.cpp.ii:
$(CXXCOMPILE) -E $< > $@
since $(COMPILE) and $(CXXCOMPILE) are generated in Makefile.in.
I use these frequently when debugging, and usually add these rules to new
projects' Makefile.am's.
HTH,
Fang
