Make is not available. That appears to be initially the reason why it woht work. Time for a make test m4.!

[Rudd-O]

will close in about 5E10 seconds when the pi is done compiling lawl

nono, it's actually a thing:

I know, I know... http://forums.nas4free.org/viewtopic.php?f=61&t=260 (see picard), but still... ideas?

I would make a copy of the above program and then run the build command with V=1 to see what is being passed to GCC. It looks like the kernel build system is not setting up includes correctly.

It should be telling the C preprocessor to search /usr/src/kernels/3.4.2-3.fc17.armv5tel/arch/arm/mach-$subarch/include for headers for some $subarch, but that is not happening here.

I suspect that this is a RedHat-specific regression. This works on Gentoo with the Raspberry Pi kernel sources.

[Rudd-O]

Yah this is weird:
.fc17.armv5tel EXTRA
the architecture is actuall armv6l
Linux melody.dragonfear 3.2.27 #1 PREEMPT Mon Oct 1 22:37:41 UTC 2012 armv6l armv6l armv6l GNU/Linux

Makes no sense what they did.

[ryao]

It just occurred to me that you should use the Raspberry Pi kernel sources to build the kernel. No other kernel sources are compatible with that hardware as far as I know.

[Rudd-O]

Three days after, the kernel is finally compiled. Doing ZFS now, SPL worked. Wish me luck.

[Rudd-O]

Compile appears to work. Closing this issue.

[behlendorf]

Good news, thanks for the update.
