Hi I am trying to compile chaos,
and I get this error:

CC lib/h2/xen/xc.o
lib/h2/xen/xc.c:46:21: fatal error: xencall.h: No such file or directory
compilation terminated.
lib/h2.mk:23: recipe for target 'lib/h2/xen/xc.o' failed
make: *** [lib/h2/xen/xc.o] Error 1

I built xen by cloning it from https://github.com/xen-project/xen.git and modified config file with XEN_ROOT and PREFIX pointing at the built source(Not installed). I couldnt find the file xencall.h, Can somebody help me with this.

Hi there! You also have to set the value for XEN_PREFIX in either config.in or .config file. That should be the same value you set when configuring xen tools. That is, if you ran the ./configure command with --prefix=<my-path>, you should also set XEN_PREFIX=<my_path>.
Let us know if you have further problems.
