As far as I know all the code is organised properly and the function
prototypes provided in header files. As for adding to the Makefile -
that's where we are struggling. We have tried the following
'experiments': adding our new source files to the 'OBJS' variable
(OBJS+=s1.o s2.o); creating a migration.o directive which depends on
s1.o and s2.o (this actually produces a slightly different error:
---
In File included from s1.h:11,
from s1.c:14:
Qemu-kvm.h:11:17: error: cpu.h: No such file or directory
In File included from s1.h:11,
from s1.c:14:
Qemu-kvm.h:18: error: expected declaration specifiers of '...' before
'CPUState'
<ommitted further cascading errors>
Make[1]: *** [arc.o] Error 1
Make[1]: Leaving directory `/root/tmp/KVM2/qemu'
Make: *** [qemu] Error 2
---
This is why we are wondering if any special consideratinos need to be
made when adding to the makefile, or if there is already a howto
somewhere?
