cohttp 0.11.0 fails to compile via opam #113

ericbmerritt · 2014-04-15T16:12:25Z

I figured this would be the best place to post. The latest release of cohttp in opam fails to compile consistently.

Do you have the native code version of the native code compiler installed? That is, ocamlopt.opt. It should work without it, but it would be good to check if it work when ocamlopt.opt is actually available.

ericbmerritt · 2014-04-15T18:27:28Z

Basically things are installed like this.

- name: Add ocaml ppa
  action: apt_repository repo="ppa:avsm/ppa"
          update_cache=yes

- name: make sure essential build tools are in place
  action: apt name={{ item }} state=latest
  with_items:
    - ocaml
    - opam
    - camlp4-extra

That is the equivelent of installing your ppa and running apt-get install ocaml and apt-get install opam. I take it there is another installation I need to be doing. I will check on that as soon as I get to a place that I can.

avsm · 2014-04-15T18:33:46Z

Yeah, if you install 'ocaml-native-compilers' then it'll work. However, this should not be required, so I will leave this bug open to fix it to work even when ocamlopt.opt is not available.

shouldn't you install a compiler with opam and not use the system compiler? I'm not sure how you'd drive opam to cleanly switch compilers via ansible however.

avsm · 2014-04-15T18:35:07Z

The system compiler should work fine with OPAM, as long as it's not upgraded after the OPAM initialization (but OPAM will detect this if the system compiler version changes)

So should I need to install something extra to build cohttp?

This may have been a stupidity on my part, but is there any way to raise
this to users in opam? That is, its not quite obvious to an external user
that an opam package requires external, non-opam resources. This is true
for libraries as well as compilers. Is there a way to print out some
message on failure to tell the user 'we have requirement x and y you should
install those and try again' type of thing?

@ericbmerritt

I think there's still a problem on our end here. We should allow users to install cohttp with only the bytecode compiled compiler (ocamlopt and not ocamlopt.opt).

avsm says we have a fallback: https://github.com/avsm/ocaml-cohttp/blob/master/Makefile#L13

but it's not working...

As a general tip though you still want to have the native compiler package since it will speed up compilation a lot usually.

ericbmerritt · 2014-04-16T04:17:39Z

I just added it to our provisioning. I just didn't realize that it was needed and not installed.

Btw, I just installed ocaml-native-compiler and got the following error.

$> which ocamlopt.opt
/usr/bin/ocamlopt.opt

$> opam install cohttp

I get the same error as above after installing ocaml-native-compiler

rgrinberg · 2014-04-17T01:31:59Z

it also fails for me :/

rgrinberg · 2014-04-17T02:14:51Z

#114 fixes this i think

Fixed in cohttp 0.11.1, uploaded to opam
