RR> Which version of bjam and Boost are you using? Where do you have mingw RR> installed? I using: C:\Lang\Projects\boost Version 1.31.0 And i updating it from CVS every day. C:\Tools\bjam.exe Boost.Jam Version 3.1.9. OS=NT. C:\Lang\gnu\MinGW I install MinGW-3.1.0-1.exe And I extract current archives gcc-*-3.3.1-20030804-1.tar.gz C:\Lang\ActiveState\Python\python.exe 2.3.3 (#51, Dec 18 2003, 20:22:39) [MSC v.1200 32 bit (Intel)] from www.python.org RR> Just in case. I should mention (as I did on another post) that there is RR> a bug with Boost.Build+BJam release that prevents it from handling RR> spaces for the compiler tools. If that's your situation try installing RR> mingw to a location without spaces. RR> HTH.
