### Cross compile ### Cross compile
Set `CC` and `FC` to point to the cross toolchains, and set `HOSTCC` to your host C compiler. Set `CC` and `FC` to point to the cross toolchains, and set `HOSTCC` to your host C compiler.
The target must be specified explicitly when cross compiling. The target must be specified explicitly when cross compiling. The `CROSS=1` flag should be specified.
