Wenxian, It seems you have encountered a problem with the netCDF library being built. I've made a patch available that I believe will solve this problem. http://www.unidata.ucar.edu/staff/mjames/gempak/gempak_netcdf_upd_201007.tar.gz save an uncompress in $NAWIPS cd to $NAWIPS/extlibs/netCDF/ "make clean" rm $OS_LIB/libnetcdf.* "make all" Hopefully this should complete without any problems. Please let me know either way. Best, Michael James Unidata User Support > Dear Sir/Madam, > > I tried to build the gempak5.11.4 source version. Lots of errors occurred. > Could you please help me?
