<dramforever> Hello! I've just got started with OCaml and got into a problem
<dramforever> I'm following the instructions of Real World OCaml, but failed at the "opam install core utop" step here: https://github.com/realworldocaml/book/wiki/Installation-Instructions#configuring-opam
<dramforever> Wait, I'll post the logs
<lpaste> dramforever pasted “opam install core utop” at http://lpaste.net/170063
<dramforever> Now that's a huge log and I got confused just trying to find out what to google... Anyway thanks in advance
<dmbaturin> dramforever: If you are using opam, it's better if you install the ocaml compiler through opam too. Externally installed compiler can be... tricky.

<dramforever> dmbaturin: Thanks! I'm trying it now
<dramforever> (Sorry for the long delay, I just got disconnected but saw your response through the logs)

<adrien> justin_smith: lablgtk2.auto-init is handy but is not necessarily the best way: if your program takes arguments, it means that "foo --help" will require a graphical display
<adrien> so it depends on the kind of program you're making

<mehdid> I have a little project (built using oasis) where source is in src/ and documentation should be generated in doc/
<mehdid> but ocamlbuild fails with "Ocamlbuild knows of no rules that apply to a target named ../src/Opensource.odoc"
orbifx has quit [Ping timeout: 276 seconds]
<mehdid> does anyone know how to sort this out?
<Algebr`> mehdid: I think you did to provide a doc thing
<Algebr`> example:
agarwal1975 has joined #ocaml
<Algebr`> hmm, forgot steps exactly but oasis can generate what you need
<Algebr`> here's what I use: http://pastebin.com/d0Hv2iSn
<Algebr`> what happens if you do oasis setup
<Algebr`> then make doc
<mehdid> it runs fine
<mehdid> until it reaches the doc
<mehdid> but "oasis setup" doesn't complain
sh0t has joined #ocaml
<Algebr`> same error?
<mehdid> well, yes, I didn't change anything yet so the error is still the same
<mehdid> It seems to work with this change:
<mehdid> - XOCamlbuildLibraries: opensource
<mehdid> + XOCamlbuildModules: src/Opensource
<Algebr`> yay
<mehdid> but fails now for the "Document distrbution" part
<mehdid> I blame gildor for making complicated wrappers on top of simple tools :-)
<Algebr`> Drup: ping
<Algebr`> err, nvm

<SomeDamnBody> Is there a way to get a list of all components of a graph? As in, say a graph contains two discrete graphs. How can I get A and B as separate graphs?
<flux> somedamnbody, you're looking for an algorithm or a function in OCamlGraph?
<Drup> SomeDamnBody: ocamlgraph.
<Kakadu> SomeDamnBody: The function you asked yesterday is enough
Simn has quit [Read error: Connection reset by peer]
<SomeDamnBody> kakadu: strongly connected components may find a subset of A or B
ggole has quit []
<SomeDamnBody> Because my graph is directed. I need all of A and all of B, but recognizably discrete
<Kakadu> Ah, it was about strong components...
<SomeDamnBody> kakadu: yes, that was yesterday. Different question today
<SomeDamnBody> Drup: an algorithm in ocamlgraph
<Drup> SomeDamnBody: just turn your graph to non-directed and compute components
<SomeDamnBody> I was wondering if that would work
<SomeDamnBody> Ok, well, I gotta find out how to make it undirected...
malc_` is now known as malc_
<SomeDamnBody> wait... wouldn't iter_vertex of a Directed graph signature still qualify the module type for an undirected graph as specified in the Components.Undirected??
<SomeDamnBody> That would sure be easy...
