Re: puzzled on how to integrate arm kernel patch(es) into crosstool

I'm not sure if this is exclusively an arm-specific kernel header missing issue or whether it is specific to at91. One of the developers was unable to build his arm (at91?) specific code without adding a directory of arm specific header files (obtained from a 2.95.3 arm environment) and changing the symlink:

.../arm-arm9-linux-gnu/sys-include/asm/arch-at91

modified the link "arch" to point at "arch-at91" rather
than "arch-integrator".

Aha. Can you send me a test file from that developer I can use to check whether my toolchain comes with the right include files? One that doesn't compile with the vanilla crosstool?

Now the code compiles -- but where is the "pristine" source of this? would the rmk patch ftp://ftp.arm.linux.org.uk/pub/armlinux/source/kernel-patches/v2.4/patch-2.4.21-rmk1.bz2
have this code? I suspect not, as reading this email


http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2004-January/019067.html

So I feel like I am on the verge of success with having a fully-functional arm cross-compiler using crosstool (v0.25)...

Yeah, sounds like you're close. I'll try to pay attention to the thread you linked to.

Next I need to build a minimal embedded environment (ptx again?)...

Yes, the wonderful ptxdist. You should look at its patch repository; they may have already solved this very problem. - Dan
