Hi, I tried to build boost for iPhone on Mac OS X. If I try the following ... bjam --prefix=/somePath toolset=darwin target-os=iphone macosx- version=iphone-2.0 define=_LITTLE_ENDIAN link=static install ... the libraries will build fine, but they are i386 code, not arm, so there're unusable. But if I add architecture=arm ... bjam --prefix=/somePath toolset=darwin architecture=arm target- os=iphone macosx-version=iphone-2.0 define=_LITTLE_ENDIAN link=static install ... the whole thing just does not build. It fails very early with the following error: g++-4.0: installation problem, cannot exec '/usr/bin/arm-apple-darwin9- g++-4.0.1': No such file or directory Any ideas/hints how to build the boost libraries for the iPhone? (By the way, /usr/bin/arm-apple-darwin9-g++-4.0.1 is existing on my Mac.)
