I built in the normal fashion, with the CBE compilers (cc: Sun C 5.9 SunOS_i386 Patch 124868-10 2009/04/30), and 12u1 lint.
I'm not subscribed to zfs-discuss, but have you established whether the problematic build is DEBUG? (the bits I uploaded were non-DEBUG). -- Rich Haudy Kazemi wrote: >>> Could it somehow not be compiling 64-bit support? >>> >>> >>> -- >>> Brent Jones >>> >> >> I thought about that but it says when it boots up that it is 64-bit, and I'm >> able to run >> 64-bit binaries.
