[cpp-netlib-devel] get_real_algorithm compilation error

[Cheng L. <rhy...@gm...>]

Hi,

Today I updated my svn working directory, and, WOW, new updates! But my 
gcc 4.1.2 complains while compiling the message_transform_test.cpp:

../../../boost/network/message/transformers.hpp:21: error: non-template 
‘type’ used as template
../../../boost/network/message/transformers.hpp:21: note: use 
‘Algorithm::template type’ to indicate that it is a template
../../../boost/network/message/transformers.hpp:21: error: declaration 
does not declare anything

    "g++"  -ftemplate-depth-128 -O0 -fno-inline -Wall -g  
-DBOOST_TEST_NO_AUTO_LINK=1  -I"../../.." -I"/usr/src/boost_1_34_0" -c 
-o "bin/gcc-4.1.2/debug/link-static/message_test.o" "message_test.cpp"

As gcc suggests, I added the `template' keyword as following, and it 
works fine:

template <class Algorithm, class Selector>
    struct get_real_algorithm {
        typedef typename Algorithm::template type<Selector> type;
    };

I haven't try the original code under any version of msvc, but I think 
msvc may be more fault tolerant than gcc. I had once encountered a 
similar situation about `typename' :-)

Cheers
Cheng
