Hi Annette, Our cross-compile expert is away for 3-weekd, but I'll try to help in the meantime. We have a report from a user that this worked for 3.6.1 on a bluegene platform: F90=blrts_xlf90 CXX=blrts_xlC FC=blrts_xlf CC=blrts_xlc ./configure --build powerpc32-unknown-gnu --host powerpc-suse-linux Try that and let us know if it causes problems. We also think that 3.6.2 will cross compile if in addition you specify two extra options to the configure script: --disable-fortran-type-check --disable-fortran-compiler-check --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: IQL-963023 Department: Support netCDF Priority: Normal Status: Closed
