I successfully built release/debug versions and installed boost-1_37 under Windows Vista, Visual C++ 9.0 SP1. I use the following command: bjam --toolset=msvc --build-type=complete stage install However when I am using UBLAS, I get the following error: Error 1 fatal error C1083: Cannot open include file: 'boost/mpl/vector/aux_/preprocessed/plain/vector20.hpp': No such file or directory C:\Boost\include\boost-1_37\boost\mpl\vector\aux_\include_preprocessed.hpp 49 I checked 'boost/mpl/vector/aux_/preprocessed/plain/ and here is a listing of the files there: Directory of C:\Boost\include\boost-1_37\boost\mpl\vector\aux_\preprocessed\plain 05/11/2008 14:27 <DIR> . 05/11/2008 14:27 <DIR> .. 02/09/2004 11:41 19,378 vector10.hpp 28/11/2004 01:50 3,415 vector10_c.hpp 28/11/2004 01:50 6,556 vector20_c.hpp 02/09/2004 11:41 52,729 vector30.hpp 28/11/2004 01:50 9,747 vector30_c.hpp 02/09/2004 11:41 69,549 vector40.hpp 28/11/2004 01:50 12,937 vector40_c.hpp 02/09/2004 11:41 86,369 vector50.hpp 28/11/2004 01:50 16,136 vector50_c.hpp 10 File(s) 276,816 bytes As you can see, vector20.hpp is missing. Is tthis a legitimate problem or have I not built something correctly? Thanks for any help Andrew -- ___________________________________________ Andrew J. P.
