Hi Since updating to automake-1.14 I'm getting warnings of the form:
src/inspiral/posterior/mpi/Makefile.am:14: warning: source file '$(srcdir)/../LALInferenceMCMC.c' is in a subdirectory, src/inspiral/posterior/mpi/Makefile.am:14: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. The Makefile.am in question is (stripping out some stuff to make this clearer): CC = $(MPICC) LIBS += $(MPILIBS) lalinference_mcmc_SOURCES = \ $(srcdir)/../LALInferenceMCMC.c \ $(srcdir)/../LALInferenceMCMCSampler.c \ $(srcdir)/../LALInferenceMCMCSampler.h bin_PROGRAMS = lalinference_mcmc This code uses the source files from the parent directory but compiles them with the MPI C compiler instead of the normal compiler. The warning above is recommending to set the "subdir-objects" option but I don't think this is appropriate in this case as we want objects to be created in the directory that contains the Makefile, not the source files. Is there a way to silence this warning? Cheers Adam
