USER_FFLAGS not referenced on hopper?

[raeder]

In cesm1_1_beta04 it appears that Macros.hopp2:USER_FFLAGS is not used anywhere.
I see in models/atm/cam/bld/Makefile.in that
FFLAGS += $(USER_FFLAGS)
but that line does not show up in the Makefile when I build CAM,
so no USER_FFLAGS flags are used in the build.
Am I missing something?

Thanks,
Kevin

If you are doing a build using the CESM scripts then CAM's Makefile.in template is not used. That is only used by CAM standalone builds.

That's good to know.

But the implication is still that using the CESM scripts rules out using USER_FFLAGS to
set compiler flags. If that's intentional, to prevent users from setting flags that would cause
problems, that's sort of OK, but there should be a note where USER_FFLAGS is set saying that
it doesn't actually do anything, at least on hopper.

Hi Kevin,

You are correct USER_FFLAGS is no longer used. You can either edit FFLAGS directly or use USER_FFLAGS and add a line at the end
of Macros.hopp2

FFLAGS+=$(USER_FFLAGS)

Thanks Jim. That's what I need to know.
