<jco> Hello!
<jco> I tried to run a small program with CamlImages but I got this error:
<jco> (Failure unsupported)
<jco> Raised by primitive operation at file "png/png.ml", line 48,
<jco> the problematic line is this one: let img = Png.load "png.png" [];;
<oni-on-ion> i wish i could help. is there some code i can try at home?
<jco> I just followed the instructions for compilation below
<oni-on-ion> ok, going to try it here
<oni-on-ion> nope., i cannot
<jco> maybe I haven't some extra packages installed on my system to make it work
<oni-on-ion> i think i might leave ocaml alone now
<jco> oni-on-ion: did you compiled the code and ran it?
<oni-on-ion> ^
<oni-on-ion> i have a new install with 4.09 and i am already in the midst of fighting with ocaml dependencies. i dont think i can continue using it like this. there is no community support
<oni-on-ion> sorry.
<jco> :'( I've struggled with opam too
<jco> oni-on-ion: you might be interest in opam switches
<oni-on-ion> i dont know anyone that uses ocaml and hav barely spoke to anyone in my life that uses it. i am not sure where people get help or support unless they are working in a company or from school.
<jco> it lets you have several installations of ocaml kept separated
<jco> in isolation
<oni-on-ion> what? opam switch is how to get an ocaml compiler.
<oni-on-ion> i am trying to fix the one i already had, i dont think this is an uncommon problem.
<oni-on-ion> these are not solutions when starting from ground zero
<oni-on-ion> these are bandaids for existing knowledge and project. but counterproductive to starting out.
<oni-on-ion> i am not in the mood to install an older version of ocaml to help with your code, sorry. i've just installed a brand new 4.09 to get my own code working again.
<jco> ok, thanks for you interest anyways :)

<rzmt> Hi, i currently have enabled more compiler warnings in dune config. I added Menhir to the project, and i'm getting warnings from the generated OCaml code. Can i use the default warnings for that single module? I enabled the warnings like this https://dpaste.org/qfus

<Fardale> oni-on-ion: people get help here, on discord or discuss
<Fardale> oni-on-ion: the error message you got from opam just told you that opam can not install camlimage because it is not compatible with ocaml 4.09.0
<Fardale> and it is a commun problem that some package are imcompatible with some other, that is why switch are important to not have too many package install in the same switch
<Fardale> for camlimage, the loading fonction is not implemented
<mahmudov> i am getting unbounded Lwt error,
<mahmudov> already installed Lwt and i did "eval 'opam config -env'"
