Hi, I want to build boost out-of-tree. Usually, this is done like this: $ mkdir /path/to/build $ cd /path/to/build $ /path/to/source/configure $ make The actual source is not modified, all output is written in the build directory. The best I could find was http://www.boost.org/doc/libs/1_52_0/more/getting_started/unix-variants.html..., but the bootstrap.sh step will still modify the source directory. How can I do a real out-of-tree build of boost? Regards, Tino
