Can anybody help me out? here's my procedures: 1. build bjam from the source. 2. run bjam "-sTOOLS=vc-7_1" "--with-python-root=D:\Python24" install After hundreds of successful items, the process suddenly stop with an error "failed to write command file!". I tried seveal times, with or without compiling python libraries, It stopped ramdonly,sometimes at the python libraries, others at the multi-thread libraries. My system is Windows XP SP2 English, with Visual studio 2003. I have have VC2005 express b2 installed. Previously, I encountered the same problem with boost 1.33b2. but i have no problem with boost 1.32 which I 've been happy with for a long time.
