Hello again, I figured it out. I'm sorry to have bothered you with this.
For those interested; I put something like this in Makefile.am, which seems to be all thats needed, and do the trick just fine: bin_PROGRAMS = prog prog_a prog_SOURCES = file1.cpp file2.cpp prog_a_SOURCES = $(prog_SOURCES) prog_a_CXXFLAGS = -DVAR_A Thanks, Camiel. iamcamiel wrote: > > 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.
