→How to cross compile the linux kernel
= How to cross compile the linux kernel =
In order to build the Linux Kernel for IGEP Processor boards PROCESSOR BOARDS it's recommended to cross-compile the kernel, that's, build the kernel in your HOST machine for a target architecture.
To setup the cross-compiling there are two fundamental variables that the kernel uses to select the target architecture. Normally these values are guessed based on your build environment, but of course that environment here does not match our target embedded system, so we'll need to override them. The variables in question are ARCH and CROSS_COMPILE.
The ARCH variable is the architecture you're targetting as the kernel knows it. For IGEP Processor Boards PROCESSOR BOARDS you'll set to "arm" architecture.
Hopefully the CROSS_COMPILE variable is pretty self-explanatory. Set this to the prefix of your toolchain (including the trailing dash "-"). So if your toolchain is invoked as say arm-linux-gnueabi-gcc, just chop off that trailing gcc and that's what you use: arm-linux-gnu-.
