Please let us know if this doesn't work. --Russ > Now the compilation goes well but the make check > fails: > > [...] > ld: 0711-317 ERROR: Undefined symbol: .nf_get_var1_int1_ > ld: 0711-317 ERROR: Undefined symbol: .nf_get_var1_int2_ > ld: 0711-317 ERROR: Undefined symbol: .nf_get_var1_int_ > ld: 0711-317 ERROR: Undefined symbol: .nf_get_var1_real_ > [...] > > Namely all the Fortran 77 API are "undefined symbol". > If I reinstall both C and Fortran libraries > without "-qextname" option for xlf/xlf90 > (no trailing underscore for Fortran routines) > then all the C APIs (nc_get_var... etc.) > become "undefined symbol" > > In any case I can't succeed in linking > a Fortran program with the new libraries, > > do you have any suggestion/recommendation? > > Thanks in advance, > Regards > > Andrea Storto > > > Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: XZT-324632 Department: Support netCDF Priority: Normal Status: Closed
