Linux Kernel Cross Compile, 32 headers and compile the kernel and the headers yourself or find the right package.

Linux Kernel Cross Compile, Using apt to keep Raspberry Pi OS up to date also keeps your Linux kernel and firmware up to date, since Raspberry Pi distributes them as Debian packages. Cross-compiling a Linux kernel involves building the kernel on one platform (the host) for use on another platform (the target). 15. Assume that PingWu wants to compile the General rules: there is a correlation between gcc and binutils releases, use simultaneously released versions; it is better to use latest kernel headers to compile libc but use - The CROSS_COMPILE variable should be set to the prefix of the toolchain (CTARGET), including the trailing dash.
