I am unable to duplicate this error even with the 3.2.17 version of
db3. Specifically, I rebuilt from source the files available on:


and this compiles cleanly:

/* x.cpp */
#include <db_cxx.h>
main ()
  int major, minor, patch_level; 
  DbEnv::version(&major, &minor, &patch_level);
  return 0;


    g++ -o conftest -g -O2   x.cpp -ldb3_cxx

which is the test that is failing in your config.log with:

configure:2993: g++ -o conftest -g -O2   conftest.cc -ldb3_cxx >&5
In file included from /usr/include/c++/3.2/backward/iostream.h:31,
                 from /usr/include/db_cxx.h:52,
                 from configure:2975:
/usr/include/c++/3.2/backward/backward_warning.h:32:2: warning: #warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section of the C++ standard.

configure:2996: $? = 1

Which doesn't make a whole lot of sense to me as

    DbEnv::version(int*, int*, int*)

is a standard and benign function, unless there is a compatibility
issue between libraries compiled with 2.95 and 3.2.

That's it!

Thanks for all your help,
