Hi Hollis and Avi, I run into a compile problem with libkvm when compiling kvm-49. It caused the compile problem mentioned in my email yesterday.
It has to with the line in libkvm/Makefile CFLAGS += -I $(KERNELDIR)/include when compiling kvm-49 (git or snapshot), this include points to my resident kernel's version of kvm.h instead of the local one copied with "make sync LINUX=<kvm git repo>"). in kvm-48, KERNELDIR points to the kvm-userspace/kernel/ directory (under the git repo), but in the more recent versions it changes to /lib/modules/2.6.22.9-61.fc6/build/include. Here are the compiles from kvm-48 (kvmctl.c) and 49 (libkvm.c) respectively, kvm-48: gcc -m64 -I /home/cam/research/KVM/Sakwatamau/kvm-48/kernel/include -MMD -MF ./.kvmctl.d -g -fomit-frame-pointer -Wall -fno-stack-protector -c -o kvmctl.o kvmctl.c kvm-49: cc -MMD -MF ./.libkvm.d -g -fomit-frame-pointer -Wall -fno-stack-protector -I /lib/modules/2.6.22.9-61.fc6/build/include -c -o libkvm.o libkvm.c what is KERNELDIR supposed to point to - the install location for the modules or the location of kernel source? When configuring, I tried setting --kerneldir to the repo copy, but that didn't work. Thanks, Cam Hollis Blanchard wrote: > Move libkvm into its own directory.
