Dear Boost users: I have been successful in using boost under gcc 4.3. (running Linux FC9). I wanted to try compiling under Windows environment - Borland C++ 2007. A simple program using "boost/numerics/ublas/vector.hpp" will not compile. I got errors like: [BCC32 Error] is_reference.hpp(46) E2135 Reference cannot be declared 'const' or 'volatile' etc. I have looked at the header file "is_reference.hpp" to see if I could make something out of the line 46. It turns to be a "workaround" for BORLAND compiler. There is a comment to the effect "theses are illegal specializations: cv-qualifies applied to references have no effect according to [8.3.2p1], C++ Builder requires them though it treats cv-qualified reference as distinct types ..." I would like to know if any has been successful in using Borland compiler with boost library based codes. Regards, Philip Ogunbona
