Re: [Boost-users] Problems compiling Serialisation libs because o f Spirit problem

      Some more information on this...

Looking at the headers that give the error, there appears to be an issue
with the result types returned from parsers....

boost/spirit/core/parser.hpp

template <typename DerivedT>
    struct parser
    {
        typedef DerivedT                embed_t;
        typedef DerivedT                derived_t;
        typedef plain_parser_category   parser_category_t;

        template <typename ScannerT>
        struct result
        {
            typedef typename match_result::type type;
        };

boost/spirit/core/primitives/numerics.hpp

struct sign_parser : public parser
    {
        typedef sign_parser self_t;

        template <typename ScannerT>
        struct result 
        {
            typedef typename match_result::type type;
        };

The derived sign_parser class appears to want to 'override' the base class
struct result, but instead the compiler is giving an error. This would
appear to be a compiler fault, but I could be way off there - depends
whether this compiles in other circumstances!! I am still at loss to fix
this so all help gratefully received!

Subject: [Boost-users] Problems compiling Serialisation libs 
because of
Spirit problem
Hello all,
I reported some time ago an issue with trying to compile the 
Boost libs
using an ARM cross compiler.
This has just started to have an impact as I wish to try out the
Serialisation libs, and these are one of the areas with a 
compile issue.
The following error is repeated over a considerable number of 
files and
seems to indicate a problem with Spirit.
I am using the latest release version of Boost (1.33.1)- no 
patches (are
there any?) and a gcc v3.4.3 cross compiler to ARM architecture.
Does anyone have any suggestions? I have had no luck figuring 
it out, but to
be honest haven't spent a lot of time on it yet.
Rgds
James
