Re: [Boost-users] uBlas: compiler error (Borland 2007)

The compiler says:

[BCC32 Error] matrix.hpp(2671): E2247 'identity_matrix::one_' is not accessible

I have no idea what the compiler wants to tell me here. Does it means that the nested class is not allowed to access this private member? I also have no ideas about the access rules to private members for nested classes.

Apparently this the way nested classes are handled in Borland C++ 2007. Unless you declare nested classes friends they cannot access the containing class's private or protected members. I have noticed that Borland C++ is not in the list of supported compilers. However, I've found that the uBlas library in Boost 1.32 works for me if I add #define BOOST_UBLAS_NO_PROXY_SHORTCUTS before I include ublas. I haven't done extensive testing, though. Hope I'll get rid of Borland C++ sooner or later, anyway.

There is a special mailing list for ublas, where you are more likely to get help.

The Boost docs said so, but I was unable to find it on http://lists.boost.org. Oops... er... I see it's there now... must have been hiding the other day. ;-) thanks for your help Hendrik
