 This page describes how to setup a cross platform build environment where the Debian distribution and version on build host and run-time Raspberry are identical. It will install and use the same ARM libraries (libc) and header version for building the armhf binary.

   - Manual setup
 Debian's own cross-compilation documentation recommends `crossbuild-essential-<architecture>` as the normal way of installing the cross compiler.

 GCC is also used to cross compile Linux applications. Applications can be compiled for 32-bit or 64-bit Linux systems.
