Hi,
Assuming you have a.C and b.C, and you want to build b.lx, then the following
Makefile fragment will work, if you patch your Makefile.user as given below.
**** Begin Makefile Fragment ****
all: b.lx # Specify all targets to build
b.ds1 b.ds2: b.o a.o # Specify all objects to combine together
**** End Makefile Fragment ****
**** Begin Makefile.user patch ****
Index: Makefile.user

Let me know if this works for you.
