ABINIT Discussion Forums

Hello,
I'm trying to add a new functionality to ABINIT : LOTF (Learn On The Fly).
I set the folder which contains LOTF routines and modules in src/68_LOTF.
makemake and compilation are ok.

Now I would to put LOTF as "optional".
To do that I added the to config/specs/corelibs.conf the following lines:

176 [68_lotf]
177 abirules = no
178 optional = yes

but at the makemake I obtain:
[makemake] Generating Makefile.in for each directory
src/98_main/Makefile.am:88: DO_BUILD_68_LOTF does not appear in AM_CONDITIONAL
src/Makefile.am:32: DO_BUILD_68_LOTF does not appear in AM_CONDITIONAL
Makefile.am:648: DO_BUILD_68_LOTF does not appear in AM_CONDITIONAL
[makemake] Aborting now!

What I have to do ?
Have you any idea of my error?
I was looking for the doc in ~abinit/doc without success.

Thanks.
Best regards,
Marco

You have to add a corresponding option in config/specs/options.conf, or else it will not make much sense to have the build of your directory optional.

This feature is not documented because it still is under test. For now, just look within options.conf to find examples of DO_BUILD_* options.

Hello Yann,
thanks for your reply.

I was modifying the file config/specs/options.conf
The lines I added were:

[enable_lotf]
description = Activate LOTF functionality (EXPERIMENTAL)
default = no
status = new
define = HAVE_LOTF

I didn't know that the feature was under test.
And I think that when I have started to develop the file config/specs/options.conf was different
and it didn't contain DO_BUILD_* options.

Now I added:
conditional = DO_BUILD_68_LOTF

But I have the same error.
any idea?

Best regards,

I don't find anything in your private branch. Did you push it?

Yann,
I pushed it right now.
reamark that the code is totally embryonal

Marco

There is a typo in config/specs/options.conf for enable_lotf: "conditionals".

Yann,
you are right but the problem subsists.
Marco

Yann,

I am sorry.
I don't know why on my laptop it doesn't work but this morning
at the office it worked fine.
I was able to configure and compile with and without LOTF enabled.

So, for me this post is resolved.
Thanks again.

Best regards,
Marco
