Hi Joaquín It worked fine. Thanks for the quick answer. I really appreciate this. now, I can go ahead and use it in my project. regards, aashit ________________________________ From: boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Joaquín Mª López Muñoz Sent: Wednesday, February 08, 2006 1:16 PM To: boost-users@lists.boost.org Subject: Re: [Boost-users] Multi_index Container "Soni, Aashit" ha escrito: Hi Joaquín, Éric I appreciate your response, Before that I got some workaround from the web and the snippet I have written to port it to my existing project worked until I face real problem. My observation is like when I have Ordered_index with std::string, the code I have written compiles really well and works also. But when I remove this ordered_index, the code does not compile.Here is the code that compiles: <>Here is the code that does not compile: <>If you see the difference I have only two lines commented. Yes, I'm able to reproduce the problem you report under MSVC 6.0. Two remarks: * The problem does not show with the CVS version of Boost.MultiIndex (to be shipped in Boost 1.34), as it includes a number of optimizations alleviating the choking of MSVC 6.0 with very long symbol names, which is the core reason for this weird behavior. * Until you switch to Boost 1.34 (and even when you do), you can try avoiding the use of tags and using numeric identifiers instead. Tags add some stress to such a weak compiler as MSVC 6.0. The attached file is a variation of your Multi_index_container_not_working.txt file where tags have been suppressed and numerical identifiers used instead. I have checked it out to compile and work OK under MSVC 6.0. I hope this helps, please keep me informed otherwise, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
