What is the problem? Can anyone please help me to getout of this

You must be using VC7 :-) The problem occurs if you do something like this: #include using namespace std; #include It's a bug in the compiler and there is no workaround, except, don't put a "using namespace std;" statement before including the regex header - or include it before any header that does that. I'm at a loss as to why multi-index should trigger this problem, I hope it doesn't include global using statements like that. But either way, try including the regex header first and see if that fixes things.

I think I should tell you how I have creted my workspace

I have a workspace in which a) 'Win32 console application' b)'Win32 Dinamic Link Library' (This project uses Boost.multi index) c)'Win32 Dinamic Link Library (This project uses Boost.Regex).

I have used both b) and c) dll's in main (Win32 console application).

Class hirarchy is as follows

WorkSpace -> main files , multiindex files , regex files

Which multi_index files? Boost.MultiIndex is a header only library. When you say "But when I indipendently compile multiindex package and regex package both compiles without any error." what do you mean by compiling multiindex package? Could you describe what is this process you do in more detail?

in the main I am calling the methods of multiindex and regex.

Maybe can you post the file of yours where the compile error shows? If you can't for confidentiality reasons, you can either post privately of at least send the includes part. I tend to think, along with John, you're implicitly issuing a using directive, maybe in some of your headers.

Both are of diffrent DLL's.

I am using the above two class inside the main() which looks as follows

#include "URLHandler.h" #include "CacheStore.h"

[...] Well, I guess the problem is one of the two "using namespace std" (or both) that you have in URLHandler.h and CacheStore.h. I'd try removing them (and explicitly std::-qualifying as necessary). Since you're at it, I'd also remove the other using's referring to multi_index, since in general it is bad idea to have them in header files.

Unfortunately there is no easy way around these errors as they're due to a compiler bug. As has already been suggested you need to ensure there are no "using namespace std;" statements floating around. Failing that it is possible to hack the regex headers: replacing collate with collate_ or something, but that's a rather error prone process. John.

I removed all using statements in my workspace and updated the corresponding references. Everthing went without any problems but at the end I got 2 errors

Error dump:

C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\wtypes.h(1087) : error C2143: syntax error : missing ';' before 'constant' C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\wtypes.h(1087) : fatal error C1004: unexpected end of file found Error executing cl.exe.

do you have any idea about this? I am using VC 6.

The offending piece of wtypes.h looks like: typedef struct tagDEC { ... } DECIMAL; which directly clashes with your own definition of DECIMAL in URLHandler.h: #define DECIMAL 1 The solution is to use a different name for your macro. The usual recommendation to have macro names with low probability of collision is adding some weird and hopefully unique prefix, for instance some abbreviation of the name of the library or the company.

No, it doesn't. I'm also at a loss with this, let's see if Mahesh can post a little more info. Joaquín M López Muñoz Telefónica, Investigaicón y Desarrollo
