[MITgcm-support] Building with genmake 2

Sorry for the mistake in the subject ...
Dear MITgcm support,
I will try to refrase my last question. I downloaded the new version of
MITgcm, did some changes for my particular problem (modification of a
mixture between exp 4, and flt_example), like in I had in the old version,
changed CPP_OPTIONS.h, similar to what I see in exp 4, and compiled it.
Although, the compilation is different, I manage to do it with no errors.
Now I run the model, but it goes unstable very fast. Could this be due to
the way I do the compilation:
../tools/genmake 2 -makefile
make depend
make
I changed pkg_default to include the flt package, but I let genmake2
choose the build options file by itself.
Or should it be due to some new parameters in this version?
I am puzzled, because I have the same settings and the old version using
genmake runs perfect.
Thanks again,
Sergio Jaramillo
