Hi Jonathan, I was suspecting the missing assembler too as I did not see the *-as file in the $PREFIX/bin directory. To add more color to this, I have: 1. Run the contrib/download_prerequisites script 2. Configured binutils with ../binutils-2.27/configure --target=$TARGET --prefix="$PREFIX" --with-sysroot --disable-nls --disable-werror 3. Run `make` and `make install` in the new `build-binutils` directory Is there a specific flag to create the assembler in the binutils config? These are the files found in my new $PREFIX/bin directory: x86_64-apple-darwin15.6.0-addr2line x86_64-apple-darwin15.6.0-readelf x86_64-apple-darwin15.6.0-ar x86_64-apple-darwin15.6.0-size x86_64-apple-darwin15.6.0-c++filt x86_64-apple-darwin15.6.0-strings x86_64-apple-darwin15.6.0-elfedit x86_64-apple-darwin15.6.0-strip x86_64-apple-darwin15.6.0-nm x86_64-apple-darwin15.6.0-objcopy x86_64-apple-darwin15.6.0-objdump x86_64-apple-darwin15.6.0-ranlib On Fri, Jan 6, 2017 at 7:31 AM, Nick Leli <nicholasleli@xxxxxxxxx> wrote: > Hi Jonathan, > > I was suspecting the missing assembler too as I did not see the *-as file in > the $PREFIX/bin directory.
