Hi, Thanks for all your suggestions I will do more reading regarding compiler specifics Hopefuly I will upgrade my compiler this year. Ok, I had tried this approach: hndl_index_type & h_type = get<0>(ns); group_index_type& g_type = get<1>(ns); But got: error C2667: 'get' : none of 2 overload have a best conversion error C2668: 'get' : ambiguous call to overloaded function Anymore suggestions? (Pls) I do have to admit that I find It strange that all the examples on the web (1-9) compile successfully. which left me wonder what am I missing In my project.

Hi,
Trying someting like this typedef NodePtrSet::index<hndl>::type index_hndl_type; //complier complains two few arguments Note: hndl is a tag name
I assume from previous posts of yours that you're using MSVC++ 6.0, right? If so, you cannot use the syntax your_container_type::index<...>, as explained in:
http://boost.org/libs/multi_index/doc/compiler_specifics.html#msvc_60
Please have a good read at this, since MSVC++ 6.0 has serious limitations affecting the usage of Boost.MultiIndex. Making the lib work for this compiler is not for the faint of heart, although it can be done.
//// so I defined the following:
typedef nth_index<NodePtrSet,0>::type hndl_index_type; typedef nth_index<NodePtrSet,1>::type group_index_type;
OK. Note that what makes this compile, as compared with your previous attempt, is not the use of nth_index (though this might help), but your choice of global nth_index instead of
// won't work in MSVC++ 6.0 typedef NodePtrSet::nth_index<0>::type hndl_index_type; typedef NodePtrSet::nth_index<1>::type group_index_type;
as explained in the aforementioned page.
... When I try to write group_index_type& g_type = get<group>(ns); // tag<group> complier tells me the I have to increase /Zm which i did.(to /Zm1024) but still I receive this annoying message.
z:\boost\mpl\aux_\preprocessed\msvc60\iter_fold_if_impl.hpp(65) : fatal error C1076: compiler limit : internal heap limit reached; use /Zm to specify a higher limit
If I apply this line instead
hndl_index_type & h_type = get<hndl>(ns);
I get the following errors: //error C2667: 'get' : none of 2 overload have a best conversion //error C2668: 'get' : ambiguous call to overloaded function
What I care is to get access using my keys and I don't know how to do it
Your first problem has been reported in the past and is somewhat alleviated in the version of Boost.MultiIndex shipping with Boost 1.34; as for the second problem I don't really know what's happening, some sample code showing that behavior would be useful.
Anyway, my suggestion is that you entirely omit the use of tags (i.e, define the indices without tags) and use ordinals instead:
hndl_index_type & h_type = get<0>(ns); group_index_type& g_type = get<1>(ns);
As it happens, omitting tags seem to greatly relieve stress on the compiler. Furthermore, by using enums you can have some of the convenience of tags:
enum{hndl=0,group=1};
...
hndl_index_type & h_type = get<hndl>(ns); group_index_type& g_type = get<group>(ns);
Please try this approach and report your results back. Thank you!
I am able to run on the first one with no problem e.g doing the following NodePtrSet::iterator it = ns.find(theHandle); //works 1. How to i rewrite the latter line to explictly tell it to find theHandle?
I don't get you. This is exactly what the line above does.
2. How to I get access to the non_unique_index
Hopefully my prior suggestion on using ordinals rather than tags will help here.
This is too good to give up on
I'm glad you like the lib, despite the effort it takes to make it work under MSVC++ 6.0. Modern compilers don't choke that much, in case you can consider upgrading.
Good luck with your project.
