ERRORE CONVERSIONE DI TIPO DATI

Buongiorno ,sto impazzendo da circa una settimana a compilare un codice non proprietario che ho scaricato per fare un porting su IBM POWER8. Il punto focale è risolvere questo errore, per proseguire.
Non capisco nel file Conversion.h cosa vi sia di sbagliato ,
e soprattutto non capisco da questa parte di errore ,quale funzione ed in quale file venga chiamata la memcpy. dal log
Grazie per chi volesse illuminarmi.
Buona serata .

// </reviewed>

// <synopsis>
// This class contains the general definitions for the Conversion classes.
// <ul>
// <li>
// It defines the signature for the functions converting from input
// to output format (e.g. from local to canonical format). There is
// a version where the number of values is given and a version where
// the number of bytes is given. The latter is there to be able to use
// memcpy as a conversion function (which will often be the case).
// Note that the signatures only differ in return value.
// <li>
// It defines functions to convert Bools to bits and vice-versa.
// These are used elsewhere to store Bools as space efficient as possible.
// Note that these functions are machine independent (they work on little
// and big endian machines).
// <li>
// It defines a private version of memcpy for compilers having a
// different signature for memcpy (e.g. ObjectCenter and DEC-Alpha).
// </ul>
// Static functions in the classes
// <linkto class=CanonicalConversion>CanonicalConversion</linkto>,
// <linkto class=VAXConversion>VAXConversion</linkto>, and
// <linkto class=IBMConversion>IBMConversion</linkto> convert data
// from/to canonical, VAX, and IBM/360 format, resp..
// <br>Classes derived from
// <linkto class=DataConversion>DataConversion</linkto>
// provide the same functionality in a polymorphic way.
// </synopsis>

// <motivation>
// This provides a common place for definitions used elsewhere.
// It also provides a uniform interface to memcpy.

    Re: ERRORE CONVERSIONE DI TIPO DATI

    Te lo sta dicendo lui:

    in "Conversion.h" riga 162 (

    stai tentando di convertire un puntatore a funzione con signature
    
void* (*)(void*, const void*, size_t) throw ()
    che corrisponde, risolvendo i typedef, a
    
void* (*)(void*, const void*, [b]long unsigned int[/b]) throw ()
    in
    
void* (*)(void*, const void*, [b]unsigned int[/b])
    Evidentemente, la dimensione (quello che ritorna sizeof()) di long unsigned int non e' la stessa di unsigned int per il processore POWER8.

    Devi controllare la definizione di memcopy con la tua definizione di ByteFunction.

    Re: ERRORE CONVERSIONE DI TIPO DATI

    Grazie Migliorabile!
    ho sistemato il typedef della funzione come mi avevi indicato e tutto ha funzionato.
    Ero arrivato al 60% della compilazione ma mi ha dato questo errore:
    g++: internal compiler error: Killed (program cc1plus)
    Please submit a full bug report,
    with preprocessed source if appropriate.
    See <file:///usr/share/doc/gcc-4.7/README.Bugs> for instructions.
    make: *** [obj/alert.o] Error 4
    Ho letto che trattasi di esaurimento memoria, ho esteso la swap e le cose sono andate.

    Fino al 70% con nuovo errore, e questa la vedo veramente tosta per me,provo a vedere se riesci a darmi n indicazione, se si, te ne sarei grato:
    exception specifier?
    Grazie mille in ogni caso e buona serata.
