Hi, I am a newbie in Xen. I just downloaded the source using bitkeeper. When I tried to compile the source, I got the following error message: make[3]: Entering directory `/usr/src/xen-2.0.bk/xen/common'' gcc -nostdinc -fno-builtin -fno-common -fno-strict-aliasing -iwithprefix include -Wall -Werror -pipe -I/usr/src/xen-2.0.bk/xen/include -Wno-pointer-arith -Wredundant-decls -O3 -fomit-frame-pointer -msoft-float -m32 -march=i686 -DNDEBUG -c ac_timer.c -o ac_timer.o gcc -nostdinc -fno-builtin -fno-common -fno-strict-aliasing -iwithprefix include -Wall -Werror -pipe -I/usr/src/xen-2.0.bk/xen/include -Wno-pointer-arith -Wredundant-decls -O3 -fomit-frame-pointer -msoft-float -m32 -march=i686 -DNDEBUG -c dom0_ops.c -o dom0_ops.o dom0_ops.c: In function `do_dom0_op'': /usr/src/xen-2.0.bk/xen/include/asm/mm.h:160: error: can''t find a register in class `BREG'' while reloading `asm'' /usr/src/xen-2.0.bk/xen/include/asm/mm.h:160: error: can''t find a register in class `BREG'' while reloading `asm'' make[3]: *** [dom0_ops.o] Error 1 make[3]: Leaving directory `/usr/src/xen-2.0.bk/xen/common'' make[2]: *** [/usr/src/xen-2.0.bk/xen/xen] Error 2 make[2]: Leaving directory `/usr/src/xen-2.0.bk/xen'' make[1]: *** [xen] Error 2 make[1]: Leaving directory `/usr/src/xen-2.0.bk'' make: *** [world] Error 2 SOS:)
