Hello everyone,
I've finally gotten around to learning to use the autotools for an
open-source project I'm working on, and I run into one thing that I can't
figure out how to do.
I have one program, that can be built in four different variants. The
variant is choosen by defining a macro, and affects lots of sources. The
four variants are always needed.
In the current makefile, this is solved by doing some substitutions (I'll
just show two variants):
VAR_A_CFLAGS = -DVAR_A
VAR_A_OBJS = $(subst .o,.do,$(OBJS))
.SUFFIXES: .ova
.cpp.o:
$(CC) $(CFLAGS) -c $< -o $@
.cpp.ova:
$(CC) $(CFLAGS) $(VAR_A_CFLAGS) -c $< -o $@
all: prog prog_a
prog: $(OBJS)
$(LD) $(LDFLAGS) -o prog $(OBJS)
prog_a: $(VAR_A_OBJS)
$(LD) $(LDFLAGS) -o prog_a $(VAR_A_OBJS)
Is there a standard way of doing something like this when using the
autotools?
Thanks,
Camiel.
