HP-UX, aCC and namespace std

[Mihai Matei <mi...@yahoo.com>]

Hi,

    Summary: 'using namespace std' does not work with Xerces-C 2.7.0 on hp-ux 11.11 parisc and aCC A.03.73

    Long version:
    I have the following problem with Xerces-C 2.7.0, I'm compiling on hp-ux parisc 11.11 with aCC A.03.73:

    #./runConfigure -php-11 -ccc -xaCC -ok
    #gmake                                             -ok

    #file libxerces-c.sl.27.0
    libxerces-c.sl.27.0:    PA-RISC1.1 shared library -not stripped

    #ldd libxerces-c.sl.27.0 |more
        /usr/lib/libnsl.1 =>    /usr/lib/libnsl.1
        /usr/lib/libxti.2 =>    /usr/lib/libxti.2
        /usr/lib/libpthread.1 =>        /usr/lib/libpthread.1
/usr/lib/dld.sl: Unresolved symbol:     symbol not found: __PureVirtualCalled   (libxerces-c.sl.27.0)
    ...(above line repeated)
    That's ok, the examples work:

    #../bin/CreateDOMDocument
    The tree just created contains: 4 elements.

BUT!!!

    My question is why is Xerces picking up the 'old' header file <iostream.h> instead of <iostream>? I searched in the source code for the XERCES_NEW_IOSTREAMS macro, it is defined for a few architectures, but could not fine it defined for hp-ux/aCC. 
    The problem is when I try linking my program with the C++ Standard Lib, I compile with '-AA', and link with '-lstd_v2 -lCsup_v2'. If I do this, the example would not work anymore! 
#./test
The tree just created contains:  <-- nothing
...and other examples even abort

 Plus, there are a lot of comments like the following in the source code:

 * Revision 1.8  2003/05/30 09:36:35  gareth
 * Use new macros for iostream.h and std:: issues.

    What are those issues and how can I get around them?

    Then, in XercesDefs.hpp:

#if defined(XERCES_STD_NAMESPACE)
    #define XERCES_USING_STD(NAME) using std :: NAME;

    which means I cannot do a 'using std::vector' for example, because the std namespace is not defined (unless I compile with -AA, but I run into problems with Xerces, see above).

    Any ideas?

Thank you!!

You should not specify the link libraries on the command line.  Instead, 
let the compiler add the appropriate libraries based on the -A option you 
specified.

The default for the aCC compiler on PA-RISC is -Aa, which specifies the old 
standard library.  Why don't you just update the compiler option in the 
file src/xercesc/Makefile.incl to add -AA to the compile and link options? 
  Or, you can try the -z and -l options for runConfigure.

You cannot mix -Aa and -AA binaries.  You need to chose one or the other.
