20010405: netcdf-3.5.0 on hp-ux 10.20: bad g++ compiler

Michael,

We don't have access to an HP-UX 10 system -- so we can't diagnose the
problem definitively.

It appears from the configure script output in the file "config.log",
however, that your g++ installation is faulty:

    configure:1243: /usr/local/gcc-2.95.3/bin/c++ -o conftest -O3 -g -DNDEBUG  
conftest.C  1>&5
    /usr/ccs/bin/ld: Unsatisfied symbols:
       pthread_once (code)
       pthread_setspecific (code)
       pthread_getspecific (code)
       pthread_keycreate (code)
    collect2: ld returned 1 exit status
    configure: failed program was:
    #line 1230 "configure"
    #include "confdefs.h"
    #ifdef __cplusplus
    extern "C" void exit(int);
    #endif

                                    #include <iostream.h>
                                    int main() {
                                        cout << "";
                                        return 0;
                                    }

We haven't seen this problem with g++ on any other system (and we've
tested several).

I suggest that you diagnose your g++ installation problem by trying to
manuall build the above program.

Steve Emmerson   <http://www.unidata.ucar.edu>
