It's a little strange that you got this error (I haven't gotten it on any
systems I tried building on), however, here is, in my opinion, the most
logical explanation.
This has to do with LDOUT defined at the bottom of your config.h file. Mine
says: LDOUT= -o . For me, there is a space after the -o in my config.h
file. If we then look at $AMBERHOME/src/pmemd/src/Makefile, we see the
lines:
pmemd$(SFX): $(NETCDF) $(OBJS)
$(PMEMD_LD) $(PMEMD_OPTFLAGS) $(LDOUT)$. $(OBJS) $(PMEMD_NETCDFLIB)
$(LDFLAGS) $(PMEMD_FLIBSF)
Notice that there is no space between $(LDOUT) and $.. This is undoubtedly
the error you ran into. I think it would be a better idea to simply put a
space between those options in the Makefile, but perhaps there is a good
reason why that's not done (i.e. for compatibility with other, non-GNU
unices? I have no experience with those). My guess is that something
removed that extra space at the end of -o in your config.h file...
Ross and/or other developers, should we patch the Makefile to put a space
there? (and the same for pmemd.MPI and pmemd.cuda as well)
All the best,
Jason
