Re: An compiling error regarding "crtbegin.o"

Thank you, Kate.
Well, obviously not everything got cleaned out. Try recompiling arpack with gfortran. Everything, including netcdf-fortran, has to be compiled with the same compiler.
I will discuss with the system manager!

Typo in adjoint biology codes

I found typos in the adjoint codes for biology.

For example, in ad_npzd_iron.h, line 900,
add_cff should be ad_cff.

Re: ROMS mex compiles .f files (within rnt toolbox)

Thanks! I will try it again with old Matlab version.

I used to use mex files, but after immigrating to a new system, they do not work well.
And I recall that the old system had older Matlab version.
