Hi all, In a recent post (a few weeks ago), someone asked if it is possible to remove the compiler name/version from the library name. i.e., libboost_math_c99-gcc43-mt-1_37.so --> libboost_math_c99-mt.so Someone replied that adding "--layout=system" to bjam would do the trick and indeed, that worked. When compiling Boost, I was wondering if it is possible to add this parameter to the user-config.jam file, rather than editting the Makefile directly? If so, what would be the syntax to do this? Somewhere, I read that user-config.jam "define[s] available toolsets" -- I guess this parameter is not a toolset, so it is not possible? The reason I am asking is rather silly -- but just that editting the Makefile is slightly more error-prone than sending a user-config.jam to someone (or backing it up myself for later use) since the Makefile could change based on what configure outputs. Thank you! Ray
