Thank you very much for the assistance. It got my through that error, but I've smacked headlong into another one. My user-config.jam now specifies the compiler with the following line using gcc : android : $(androidNDKRoot)/toolchains/arm-linux-androideabi-4.7/prebuilt/$(androidPlatform)/bin/arm-linux-androideabi-g++ compileflags="--sysroot=$(androidNDKRoot)/platforms/android-8/arch-arm/ -I$(androidNDKRoot)/sources/cxx-stl/gnu-libstdc++/4.7/include -I$(androidNDKRoot)/sources/cxx-stl/gnu-libstdc++/4.7/libs/armeabi/include" ; I've played around with adding spaces before and after the equal sign in compileflags="--sysroot...", but in all cases I got an error similar to: arm-linux-androideabi-g++.exe: error: compileflags=--sysroot=/cygdrive/c/Android/android-ndk-r8d/platforms/android-8/arch-arm/: No such file or directory If I leave that compile flag out, the error recurs for the next -I compile flag. I have verified that directories exist at each of those paths. When trying the alternate format I came across for compile flags, which changes the compiler line to this: using gcc : android : $(androidNDKRoot)/toolchains/arm-linux-androideabi-4.7/prebuilt/$(androidPlatform)/bin/arm-linux-androideabi-g++ <compileflags>--sysroot=$(androidNDKRoot)/platforms/android-8/arch-arm/ <compileflags>-I$(androidNDKRoot)/sources/cxx-stl/gnu-libstdc++/4.7/include <compileflags>-I$(androidNDKRoot)/sources/cxx-stl/gnu-libstdc++/4.7/libs/armeabi/include ; I get a four instances of the following error when I attempt to run b2: /bin/sh: compileflags: No such file or directory I've also tried with a space between <compileflags> and the flag, but I get the very same errors. I really do appreciate your initial help. It would help me immensely if you could offer any advice on this next problem as well, or could point me to somewhere that I could learn to work through these problems for myself. The particulars about how things need to be formatted / spaced aren't obvious to me, and I haven't had luck finding relevant documentation.
