As I've been getting into embedded systems I've noticed that some projects (Arch Arm and OpenBSD for example) frown upon cross compiling. What is the reasoning for this? Is a cross-compiled binary somehow different from a natively compiled one?
OpenBSD suggests that building on the hardware ensures that the system is fully functional (and also self-hosting) and that makes complete sense. But do people actually develop and compile kernel drivers on the hardware they are developing for? It sounds very time consuming.
From OpenBSD FAQ:
"Cross-compiling tools are in the system, for use by developers bringing up a new platform. However, they are not maintained for general use."
I'll see if I can hunt down the IRC log where a developer from ArchLinux Arm told me that they don't cross compile, though they seem to have updated their info on cross-compiling with DistCC: http://archlinuxarm.org/developers/distcc-cross-compiling
