================= Cross-compilation ================= If you are planning to perform cross-compilation e.g. for Linux/Aarch64, you will probably want to use experimental feature ``--enable-bootstrap`` in your ``.mozconfig``. Then, you just have to specify the the target arch, after which the build system will automatically set up the sysroot. For example, cross-compiling for Linux/Aarch64: .. code-block:: text ac_add_options --target=aarch64-linux-gnu ac_add_options --enable-bootstrap
