Hello, It is my first time with RegCM. I did the 'configure' and 'make' like userguide says. I,am trying the testcases with new version on my PC. But, I've got an error: Opening /RegCM-4.3.5/GLOBEDAT/SURFACE/GTOPO_DEM_30s.nc NetCDF: Unknown file format mod_rdldtr.F90 : 139:NetCDF Error: -51 Aborted (core dumped) what should I do? thanks Anel
