Hi, I'm trying to build Boost on windows 7, I'm using rubenv mingw+gcc-4.8 (from here: http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Wi... ). I tried the usual way: "bootstrap gcc" and ".\b2". But at the beginning of the building process a weird crash happens with a windows message dialog of "Keyboard History Utility has stopped working". It happens even with the suppressing option ('-d0'). In the process list I see that this Keyboard Utility is called "doskey.exe". What is happening? Is it possible to build boost with gcc-4.8 on windows? Thanks for your attention, Alessandro Stamatto.
