Problems installing Column Radiation Model, using gfortran compiler. netCDF undefine

[javier_reggae@gmail_com]

Hello all,

I am trying to compile and Install the Software Column Radiation Model (CRM) for scientific atmospheric applications. I am using UBUNTU 9.04.

Originally the code uses the PGF90 compiler, and I don´t have this compiler. I have gfortran 4.4. I am trying to make the translation to gfortran.
I am having some troubles:

gfortran-4.4 -o ../bin/crm ../obj/crm.o ../obj/netcdf.o ../obj/endrun.o ../obj/freemem.o ../obj/getmem.o ../obj/blkdat.o ../obj/resetr.o ../obj/orb.o ../obj/albocean.o ../obj/aermix.o ../obj/cldefr.o ../obj/cldems.o ../obj/fmrgrid.o ../obj/radabs.o ../obj/radclr.o ../obj/radclw.o ../obj/radcsw.o ../obj/radctl.o ../obj/radded.o ../obj/radems.o ../obj/radini.o ../obj/radinp.o ../obj/radoz2.o ../obj/radtpl.o ../obj/torgrid.o ../obj/trcab.o ../obj/trcabn.o ../obj/trcems.o ../obj/trcmix.o ../obj/trcplk.o ../obj/trcpth.o ../obj/zenith.o ../obj/intmax.o ../obj/isrchfgt.o ../obj/isrchfle.o ../obj/wheneq.o ../obj/whenfgt.o ../obj/whenflt.o ../obj/whenne.o -L/usr/lib -lnetcdf

collect2: ld returned 1 exit status
make: *** [crm] Error 1

someone know how to solve this ??
I was read a lot of post with similar errors, and I think that this is linkage problem, but I couldn't solve it.

Really I will appreciate your help,

thanks in advance...
Javier.

This may have something to do with the double underscore in the linked references, whereas some c interfaces expect a single underscore.

There were some wierd problems with underscores when linking programs complied with gfortran after version ~4.2..... so you could give it try with netcdf compiled with different version of gfortran or using older version of g fortran like 4.0 or so...
