I have a problem to install netCDF4.0.1 on my linux 64bit machine, with PGI-10.6 I followed the instruction on this page for netCDF4.0.1 and PGI2010 exactly http://www.pgroup.com/resources/netcdf/netcdf40_pgi2010.htm I used export FC=$PGIHOME/linux86-64/10.6/bin/pgf90 and so on to set the env. But I still had this error when executed "./configure --prefix=/home/netcdf-4.0.1" ============= checking if Fortran "byte" is C "signed char"... configure: error: Could not compile conftest.c ============= Any change that I need to do to make it work? Thank you very much.
