Hello all,

Suppose you have the following

libfoo_la_SOURCES = \
    one.c \
    one.cpp \
    two.c \

I need the library to contain both the C object files and the C++ object files.  There are two ways that I can think of to do this: the easy way and the hard way.  The easy way would be two rename either the C or the C++ source files so that they do not have the same basename and thus the object files would have different names.

The hard way would be to add additional variables and rules to so that the object files use different suffixes.  Suppose you use .co, .clo, .o, and .lo suffixes for the static C object file, shared C object file, static C++ object file, and shared C++ object file respectively.  Using the latest versions of Autoconf, Automake, and Libtool, you would first need implicit rules to create the .co and .clo files.

.SUFFIXES: .c .clo .co .lo .o .obj
        source='$<' object='$@' libtool=no \
        depfile='$(DEPDIR)/$*.Po' tmpdepfile='$(DEPDIR)/$*.TPo' \
        $(CCDEPMODE) $(depcomp) \
        $(COMPILE) -c `test -f $< || echo '$(srcdir)/'`$< -o $@

        source='$<' object='$@' libtool=yes \
        depfile='$(DEPDIR)/$*.Plo' tmpdepfile='$(DEPDIR)/$*.TPlo' \
        $(CCDEPMODE) $(depcomp) \
        $(LTCOMPILE) -c -o $@ `test -f $< || echo '$(srcdir)/'`$< -o $@

Now you'd have to link the C object files with the new suffixes into the target shared library.

libfoo_la_COBJECTS = $(libfoo_la_OBJECTS:.lo=.clo) $(libfoo_la_COBJECTS) $(libfoo_la_OBJECTS) $(libfoo_la_DEPENDENCIES)
        $(LINK) $(libfoo_la_LDFLAGS) $(libfoo_la_COBJECTS) $(libfoo_la_OBJECTS) $(libfoo_la_LIBADD) $(LIBS)

So how would the static library get built?  Did I get the shared library parts right?
