[Xen-users] [SPAM] xen 4.0.0 compilation fails in function cpuid
I am using gentoo as a hypervisor and dom0. I''ve successfully built a 32bit 2.6.34 dom0 kernel and installed gentoo''s xen 4.0.0 package. However, compilation of the xen-tools package fails: xen-detect.c: In function ''cpuid'': xen-detect.c:43: error: can''t find a register in class ''BREG'' while reloading ''asm'' xen-detect.c:43: error: ''asm'' operand has impossible constraints The outcome is the same when I attempt to build from the official xen 4.0.0 hypervisor and tools source distribution (xen-4.0.0.tar.gz from xen.org). I have had success building this in a different, but similar, gentoo environment, so I assume there is something amiss with my toolchain or the gcc options I''m using. Any pointers toward a fix would be appreciated. Thanks. -mike d. P.S. I''ve heard that the "hardened" use flag I''ve got enabled can cause problems so I''m removing it and rebuilding tonight.
