expected unqualified-id before ‘:’ token

[mahmoodn]

I have a program which uses boost 1.33.1 and it works fine with gcc 4.1 however now that I want to compile with gcc 4.4 it get many errors. For example somewhere in the boost files, it says:
/opt/boost_1_33_1/boost/mpl/aux_/numeric_op.hpp: 250: error: expected unqualified-id before ‘:’ token

the code at that line is (note the second line):

#if !defined(BOOST_MPL_CFG_MSVC_ETI_BUG) 
    : AUX778076_OP_IMPL_NAME<    
          typename AUX778076_OP_TAG_NAME<N1>::type
        , typename AUX778076_OP_TAG_NAME<N2>::type
        >::template apply<N1,N2>::type
#else
    : aux::msvc_eti_base< typename apply_wrap2<
          AUX778076_OP_IMPL_NAME<
              typename AUX778076_OP_TAG_NAME<N1>::type
            , typename AUX778076_OP_TAG_NAME<N2>::type
            >
        , N1
        , N2
        >::type >::type
#endif

I know that boost 1.33.1 is old however I checked numeric_op.hpp in the latest boost release at http://svn.boost.org/svn/boost/trunk/boost/mpl/aux_/numeric_op.hpp and it is the same as before.

So any idea to solve that? thanks

We don't want an example of the errors, we want the first error or given that this is a template issue the first 5 - 10 errors.

Once you have 1 error anything that follows is suspect because if may be on code that is correct but being interpreted incorrect because of that first error.

Also when you post code post the whole statement, what you have posted looks like it might be the base class clause of a class definition but we can't tell because you've missed out the beginning of the statement.

I hope I provide the right information you wanted

[Banfa]

Actually I was hoping for a little more of numeric_op.hpp, the lines before what you have already posted but part from that very impressive detail.

Sorry for that. You may find this code snippet.

I find the solution fairly easy....
I did a diff for numeric_op.hpp between 1.33.1 and current 1.46 (revision 70743) and found little differences in lines between two files. I did replace the old one with new one and the error disappeared.

I want to upload the files but don't see any attachment link. Where can I upload the files?
