Hi Prabhakar, > *./TextMap: error while loading shared libraries: libnetcdf.so.4: cannot > open shared object file: No such file or directory* indicates an error in linking your program with the netCDF libraries. What are the command lines you use to compile and link your program? For example, when I compile and link the example C++ program in examples/CXX/simple_xr_wr.cpp, I use: $ CC -I/local/netcdf/include -g -c simple_xy_wr.cpp $ CC -g -L/local/netcdf/lib -o simple_xy_wr simple_xy_wr.o -lnetcdf_c++ -lnetcdf after installing in /local/netcdf. It's possible libnetcdf.so.4 is a leftover symbolic link to a previous version of a library in a directory you specify with -L or in your LD_LIBRARY_PATH. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: YFV-140332 Department: Support netCDF Priority: Normal Status: Closed
