[omniORB] Compiling omniORBpy with aCC A.03.63 on PA-RISC

[Matej Kenda]

Hi,

We made an upgrade of HPUX compiler aCC for PA-RISC to version A.03.63.
Compiling omniORBpy (64-bit) failed with error:


aCC -c +O0 -AA -mt +DD64 +z -DOMNIPY_MAJOR=2 -DOMNIPY_MINOR=5   -
I../../../../include/omniORB4/internal -I../include -
I/usr/local/aCCPython/include -DPYTHON_INCLUDE="<python2.3/Python.h>" -

pyFixed.o

"pyFixed.cc", line 99: error #2309: more than one instance of
constructor 
          "CORBA::Fixed::Fixed" matches the argument list: 
            function "CORBA::Fixed::Fixed(int)" 
            function "CORBA::Fixed::Fixed(unsigned int)" 
            function "CORBA::Fixed::Fixed(CORBA::LongLong)" 
            function "CORBA::Fixed::Fixed(CORBA::ULongLong)" 
            function "CORBA::Fixed::Fixed(CORBA::Double)" 
            function "CORBA::Fixed::Fixed(CORBA::LongDouble)" 
            argument types are: (long) 
        CORBA::Fixed f(l); 
                       ^

When the code was modified as suggested in the attached patch (replacing
long with int), compile succeeded, but the compiler issued a warning:

Error (future) 229: "pyFixed.cc", line 99 # "Ambiguous overloaded
function call; a function match was not found that was strictly best for
ALL arguments. Two functions

    that matched best for some arguments (but not all) were
"CORBA::Fixed::Fixed
(double)" ["../../../../include/omniORB4/CORBA_Fixed.h", line 78] and

    "CORBA::Fixed::Fixed(unsigned long
long)" ["../../../../include/omniORB4/CORBA_Fixed.h", line 75]."
Choosing "CORBA::Fixed::Fixed(double)"

    ["../../../../include/omniORB4/CORBA_Fixed.h", line 78] for
resolving ambiguity. 
            CORBA::Fixed f(l); 
                         ^

Those two declaration of constructors don't look overloaded to me.


Is replacing long with int in the aforementioned case safe for all
platforms?

If CORBA::LongLong would be used instead of long, the warning wouldn't
be reported, however LongLong is not supported by all platforms.

Regards,

Matej
