[MITgcm-support] taf errors

[Patrick Heimbach]

Hi Suneet,

I just tried it, and it does work the way I described in previous mail.
You have two options:

1)
Manually modify your Makefile; in the line starting with
AD_TAF_FLAGS         = -z -reverse -admark ad ...
add the following staf option:
-version 1.9.48
Although you will get a warning, it will work and produce
correct adjoint code.
Disadvantage of doing it that way is that you'll have to redo it
each time you (re-)generate your Makefile (i.e. do genmake2 ...)

Therefore:

2)
If you want to avoid having to manually change Makefile is to
modify the file adjoint_default (I gather that's the one you are using)
in directory
tools/adjoint_options/
by adding the staf flag
-version 1.9.48
to the line
FTL_TAF_FLAGS="-z -forward -ftlmark g_ -i4 -r4 -l taf_ftl.log -flow  
taf_ftl_flow.log$FTL_TAF_FLAGS"

Should work...

Cheers
-Patrick
