Helo, there are a few things, i need from the boost filesystem library, so i tried to follow these instructions: http://www.boost.org/doc/libs/1_35_0/more/getting_started/windows.html#or-build-binaries-from-source The problem is, that when i invoke bjam bjam --build-dir="C:\Documents and Settings\Kane\build-boost" --toolset=gcc stage it creates a directory structure in "C:\Documents and Settings\Kane\build-boost"... but all directories are empty. The size of the whole build-boost directory is 0 bytes. Also, bjam gives me a LOT of "failed" and "skipped" messages, so i don't think it did its job. "...failed updating 131 targets..." "..skipped 74 targets..."
