Hi people, I'm sure this subject as already been treated. I apologies for requesting it one time again. I try to compile boost libs as static libs (& multi-thread & universal & why not monolithic) and now I'm sure the ./configure compilation can't do that for me. So I began to go through the bjam way... but I'm absolutely not sure of the syntax and options to do what I want. (--build-type=static ???) My first try made me dynamic ".a" in many many folders and no ./include and no ./lib like in a standard install. And many error message when trying to copy files in the system lib directory (that I don't want to). What is the good way to compile boost on mac OS as static lib in the good folders ? (I've already done it on windows, I remember it much easyer, why ?) Germain
