Boost fails to Build with gccxml / msvc9

[lomex13@…]

Heya,

I am trying to use gccxml on Boost for a python project i want to build.

I ran a freshly-built-from-cvs gccxml:

"C:\Projects\gccxml\bin\release\gccxml.exe"   -D"_HAS_TR1=0"  --gccxml-compiler msvc9 -I... -I...
 -D"BOOST_HAS_THREADS" -D"BOOST_HAS_WINTHREADS" -D"__GCCXML__"
 "C:\Projects\python-ogre\code_generators\ogre\python_ogre.h" -fxml="ogre_1.7.2_cache.xml

(which points to)

#include "boost/python.hpp"
#include "boost/python/ssize_t.hpp"

It fails:

boost_1_51_0/boost/range/concepts.hpp:177: error: 'bool mpl_::operator==(mpl_::failed, mpl_::failed)' cannot appear in a constant-expression

And i am honestly far from understanding what went wrong. It might be connected to gccxml not setting the correct version number, as i already had Problems like #4464 using the same setup.

Can anyone please give me a hint?

I did avoid this Problems by disabling the assertions. Since my gccxml is based on gcc 4.2.1, i suspect it should just be added to the compiler blacklist at the top of boost/range/concept.hpp, pretty similar to the gcc block {{ after this: #ifdef GNUC

GNUC 4.2 has strange issues correctly detecting compliance with the Concepts hence the least disruptive approach is to turn-off the concept checking for this version of the compiler. #if GNUC == 4 && GNUC_MINOR == 2

#define BOOST_RANGE_ENABLE_CONCEPT_ASSERT 0

#endif

#endif

add this: #ifdef GCCXML

similar GNUC 4.2 issues for gccxml #if GCCXML_GNUC == 4 && GCCXML_GNUC_MINOR == 2

#define BOOST_RANGE_ENABLE_CONCEPT_ASSERT 0

#endif

#endif }} I do have an easy fix for similiar issues in iterator/iterator_concepts.hpp, but it can be done with similar blacklisting. I dont know, however, if this is the right place for workarounds, maybe there is a more "central" way to fix this.

wrong prantheses. here:

#ifdef __GNUC__
        // GNUC 4.2 has strange issues correctly detecting compliance with the Concepts
        // hence the least disruptive approach is to turn-off the concept checking for
        // this version of the compiler.
        #if __GNUC__ == 4 && __GNUC_MINOR__ == 2
            #define BOOST_RANGE_ENABLE_CONCEPT_ASSERT 0
        #endif
    #endif

    #ifdef __GCCXML__
	// similar GNUC 4.2 issues for gccxml
        #if __GCCXML_GNUC__ == 4 && __GCCXML_GNUC_MINOR__ == 2
            #define BOOST_RANGE_ENABLE_CONCEPT_ASSERT 0
        #endif
    #endif
