Hi Ted, Wow, that was a fast answer, thank you. I must have left 'include' in there as a copy/paste error. Anyway, I changed it, and tried again, but got the same result: ld: library not found for -lnetcdf collect2: ld returned 1 exit status make: *** [most3_x] Error 1 OK, now I will try Roy's suggestion! Thanks guys, will let you know. -jose On 29/07/2010, at 4:16 PM, Ted Mansell wrote: > Problem is probably here: > > OPT = -O -I/sw/lib/netcdf-gfortran/include > -L/sw/lib/netcdf-gfortran/include -lnetcdf > > should have "-L/sw/lib/netcdf-gfortran/lib" (lib instead of include after > the -L) > > -- Ted > > > > On Jul 29, 2010, at 3:13 PM, Jose Borrero wrote: > >> >> Hello everyone, >> >> I am sure this an incredibly basic question, but maybe someone can tell me >> what i am doing wrong.
