[ltt-dev] Fwd: Re: Lttng and Tiny Core?

[Medved, Michael]

I tried compiling the modules in this configuration and got the 
following error message:

CC [M] arch/x86/kvm/x86.o
arch/x86/kvm/x86.c: In function �vcpu_enter_guest�:
arch/x86/kvm/x86.c:3937: error: �prof_on__imv� undeclared (first use in 
this function)
arch/x86/kvm/x86.c:3937: error: (Each undeclared identifier is reported 
only once
arch/x86/kvm/x86.c:3937: error: for each function it appears in.)
arch/x86/kvm/x86.c:3937: warning: type defaults to �int� in declaration

make[2]: *** [arch/x86/kvm/x86.o] Error 1
make[1]: *** [arch/x86/kvm] Error 2
make: *** [arch/x86] Error 2

Help?
