[MirageOS-devel] Question about Mirage-www

[çå <sooner1943@xxxxxxxxx>]

Hello everyone,

  ÂI'm a beginner in Mirage and Ocaml. I have followed the installation instructions on the website and run several simple unikernel examples successfully. However, when I tried to build the Mirage-www unikernel, an odd error happened to me. Here is the error report:

#=== ERROR while installing hex.0.2.0 =========================================#

# make: *** [build] Error 1

Actually, I have installed the Bytes module. Here is "opam list":

# Installed packages for 4.01.0:

asn1-combinators    Â0.1.2 ÂCombinators for expressing ASN.1 grammars in OCaml

base-bigarray      Âbase ÂBigarray library distributed with the OCaml compiler

base-bytes       legacy ÂBytes compatibility library distributed with ocamlfind

base-no-ppx       Âbase ÂA pseudo-library to indicate lack of extension points support

I think base-bytes is supposed to be the Bytes module. I googled this problem and nothing helped. Could anyone help me out of this?ÂI'm truly grateful for your time!
