Thanks, that helped, I added this line in tools/build/v2/tools/darwin.jam: iphone-3.0 iphonesim-3.0 I'm now having an error message saying: error: unrecognized command line option: "-Wno-long-double" I solved that by taking this out: # - GCC 4.2 and higher in Darwin does not have -Wno-long-double. if $(version) < "4.2.0" { flags darwin.compile OPTIONS $(condition) : -Wno-long-double ; } What's the clean here, does anybody know? Thanks, Frank

Hope that's enough. ************************ using boost .138 ************************ compiler gcc 4.2 i686-apple-darwin9-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5572) (dot 10.2) Copyright (C) 2007 Free Software Foundation, Inc.
