building same source with different flags

[Ted Irons]

Am using autoconf-2.5.2, automake-1.4b, libtool-1.4b
on an ix86 box run running Suse Linux with kernel-2.4.6.

My Makefile.am contains the following  snippets:

================================================
libhrnet_la_SOURCES = \
 ascbin.cc \
 allocate.cc \
 fileio.cc \
 forward.cc \
 initall.cc \
 msc.cc  \
 nextsamp.cc \
 printnet.cc \
 make_net.cc \
 sig.cc  \
 hnet.cc

libhrnet_la_CXXFLAGS = ${HBP_CXXFLAGS}

libhrnet_la_LDFLAGS = -version-info @PIPES_VERSION@

libohrnet_la_SOURCES = \
 ascbin.cc \
 allocate.cc \
 fileio.cc \
 forward.cc \
 initall.cc \
 msc.cc  \
 nextsamp.cc \
 printnet.cc \
 make_net.cc \
 sig.cc  \
 hnet.cc

libohrnet_la_CXXFLAGS = -DHIGHER_ORDER_NET ${HBP_CXXFLAGS}

libohrnet_la_LDFLAGS = -version-info @PIPES_VERSION@

==============================================

When I run make I get the following error:

source='ascbin.cc' object='libhrnet_la-ascbin.lo' libtool=yes \

mv: cannot stat `libhrnet_la-ascbin.o': No such file or directory
make[3]: *** [libhrnet_la-ascbin.lo] Error 1

===============================================

Any ideas as to what I am doing wrong?

Thanks in advance,
