Hi Luis, I'm not sure on what system you are trying to build netCDF, but nf_test should link without commenting out any lines. In particular, the functions such as FCALLSCFUN4 are all defined in the cfortran.h header file, which is #included by ncfortran.h, which in turn is #included at the top of fort-var1io.c. To report problems, please be sure you are following the instructions for building in the netCDF installation guide: http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-install/ and when something goes wrong report the details requested here, so we can try to reproduce the problem: http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-install/Reporting-Problems.html Thanks! --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: YPJ-546994 Department: Support netCDF Priority: Normal Status: Closed
