Thanks for the bug report it's been a while since we've tried ppc64 builds so I wasn't aware they were broken.

[mailinglists35]

@tensor5 have you managed to produce a useable build for openwrt? if yes, could you post instructions?

[tensor5]

No, haven't tried since I opened the bug. I lost interest in that platform but I may give it a shot if you are.

[mailinglists35]

i have a netgear wndr4300 router and was curious if this 128mb ram and mips cpu device could handle a samba sharing a single 1Tb usb drive formatted with zfs + snapshots. alternate idea was to try freebsd mips + ports + samba + zfs

[tensor5]

I originally wanted to try ZFS on a PS3, which has 256mb ram, but then I ended up using btrfs. I'll try and see if it compiles, when I have some time.

[tensor5]

I tried today after a long time, and I was able to cross compile spl and zfs 0.6.4 for powerpc64 using linux 4.0. I haven't tested it, though.

[behlendorf]

@tensor5 that's good news. If you get a chance to load the modules and verify they work let us know!

[mailinglists35]

@tensor5 wow wow wow! would you mind sharing the result or (preferrably) the build steps?

[tensor5]

I had to edit the configure script in order to allow cross compilation; other then that it was just configure and make. I'll post the details soon.

[behlendorf]

Resolved and a ppc64 builder was added to prevent future regressions.
