Hi All, (particularly Jaakko!) While working on using BLL's operator return type mechanism in uBLAS I stumbled on the problem the recent (snapshot) GCC-3.4 has with BLL. I noticed Jaakoo checked in the following patch a few days ago as a workaround. #if BOOST_WORKAROUND(__GNUC__, == 3) && __GNUC_MINOR__ >=4 #include <vector> #else namespace std { template <class T, class Allocator> class vector; } #endif
From my own research the problem is not just restricted to 'std::vector'. It certainly also occurs with 'std::map'.
I assume (have not verified) that the problem is related to hidden template parameters in the gcc-3.4 implementations of the std containers. OR is the problem simply a bug (an regression) in gcc 3.4 Too late for gcc 3.4 but I will submit a bug report if no one else has already done so.
