I think they are nothing serious, but will occur for the second loop below for(int i = 0; i < 5; i++) { ... } for(i = 5; i > 0; i--) { ... } after i has been declared in the first loop. Although this used to work fine, the scope of the i declaration in such cases was changed during the course of the C++ standardization, so now a warning is issued. The warning can be eliminated by either declaring i outside both loops or redeclaring i in the second loop. > g++ -g -Wall -o test.exe example.o > -L/rayleigh/markus/SOFTWARE/netCDF/netcdf-3.3.1/lib -L/usr/local/lib > -lnetcdf_c++ -lnetcdf /opt/langtools/lib/end.o > > > [markus@landau] ...netCDF-TEST/FIRST > ./test.exe > Bus error This is a more serious error, and has nothing to do with the warnings above. I can't tell from this what the problem is, but it could be caused by pointer errors, exceeding the bounds of an array, etc. You will have to use a debugger or print statements to isolate where the problem is occurring. If you find that it's in the netCDF library, please send a small example that demonstrates the problem. > By the way: How to bring the whole stuff up with the hp-Compilers? > They blow off during compiling already ... I'm not sure what version of netCDF you are using, but the current version (3.4) and the previous version (3.3.1) work fine with HP compilers if you follow the instructions in the INSTALL file for HP-UX. The version before that (2.4.3) had a problem with HP's f77 compiler, a workaround for which is available from http://www.unidata.ucar.edu/packages/netcdf/known_problems_243.html The current version of netCDF is available from ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-3.4.tar.Z --Russ _____________________________________________________________________ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu
