  • A few tips you must know when compiling the Linux kernel
    A few tips you must know when compiling the Linux kernel
    To compile Linux, you usually only need to run make menuconfig to configure the modules to be compiled, and then run make. Linux defaults to local compilation, which means compiling the kernel used by the local machine. In embedded development, cross compilation is often required. To do cross compilation, you need to add macro definitions after the make command, such as cross compilation to the arm target.
