opam fails during "make depend" #1

Closed dvn0 closed 4 years ago

dvn0 commented 4 years ago

Hello,

This is a nice project, and I have some limited experience building MirageOS unikernels. I'm experiencing a problem while trying to install the dependencies:

First I run:

mirage configure -t unix

and then:

make depend

and I get this output:

  1 opam pin add -k path --no-action --yes mirage-unikernel-unipi-unix . && opam depext --yes --update mirage-unikernel-unipi-unix ; opam pin remove --no-action mirage-unikernel-unipi-unix
  2 Package mirage-unikernel-unipi-unix does not exist, create as a NEW package? [Y/n] y
  3 [mirage-unikernel-unipi-unix.~dev] synchronised from file:///home/[user]/src/unikernels/mirageos/unipi
  4 mirage-unikernel-unipi-unix is now pinned to file:///home/[user]/src/unikernels/mirageos/unipi (version ~dev)

I've also tried with hvt, and virtio targets, and the result is the same.

Hi @dvn0, what is your OCaml version (ocaml --version)? What is your mirage version (mirage --version)?

dvn0 commented 4 years ago

My relevant software versions:

The OCaml toplevel, version 4.09.0
opam 2.0.5
mirage v3.9.0

since you're on debian, maybe you're running into this issue https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=908203 -- is your opam package a 2.0.5-1?

hannesm commented 4 years ago

hmm no, due to the conduit 3 release there are some issues in respect to version constraints. I'll try to figure them out and find a solution.

oh, interesting. I am on Ubuntu actually, and yes my package is the 2.0.5-1... :/

hannesm commented 4 years ago

but 2.0.5-1 is the good one AFAICT :)

sorry for the inconvenience and late reply, I finally worked on this issue and 70092ef has a solution (which compilcates the build process slightly). if you still have trouble, please reopen this issue with an updated error message. Thanks.
