Hi!

I'm trying to build the XenServer tools on NixOS, and compiling ocaml_xenLowlevelLibs causes the following error when building against Xen 4.5.0 as officially released:
https://gist.github.com/ts468/316c69f7f0203a204d41

Could you maybe assist me in solving this issue?

Many thanks,
Thomas

I have the same error. Did you learn any more about it?

I have the same problem in Ubuntu 15.04 on x86.

As far as I remember ocaml_xenLowlevelLibs is not needed for Xen 4.5 anymore.

Hm - so the Xenctrl package in opam will not work with Xen 4.5? Are there any alternatives?
