There are many examples of these, and scripts and tools available to build them. You'll need to configure --host=, --target=, and --build=. It's a really good idea to build a fully-integrated source tree, with all of the binutils in the same source tree as gcc. This is called a "Cygnus tree" after Cygnus, which invented a lot of this stuff. (And, incidentally, where I used to work.) One question: do you have the root filesystem for your target machine? This means target headers and libraries. If you do that'll make things veru much easier. http://crosstool-ng.github.io/ is a thing which is supposed to support Canadian crosses. -- Andrew Haley Java Platform Lead Engineer Red Hat UK Ltd. <https://www.redhat.com> EAC8 43EB D3EF DB98 CC77 2FAD A5CD 6035 332F A671
