[elm-discuss] elm-make commands fails on Freebsd while working on MacOS

[Julien Wazné]

Hello,


I've having a problem to compile ELM code on Freebsd server while
everything is OK on my laptop (MacOS Sierra).


Here's the command that fails on freebsd : elm-make --yes --output
../static/vendor/app.js App.elm

*I cannot find module 'Users.Model'.*
*Module 'Types' is trying to import it.*
*Potential problems could be:*
** Misspelled the module name*** Need to add a source directory or new
dependency to elm-package.json*

Application structure looks like this:
[image: image]
<Loading Image...>

users/Model.elm starts like this:
module Users.Model exposing (..)


Types.elm starts like this:
module Types exposing (..)

import Users.Model exposing (..)


elm-package.json like this:
{
"version": "1.0.0",
"summary": "helpful summary of your project, less than 80 characters",
"repository": "https://github.com/user/project.git",
"license": "BSD3",
"source-directories": [
"."
],
"exposed-modules": [],
"dependencies": {
...
},
"elm-version": "0.18.0 <= v < 0.19.0"
}


I've installed ELM on freebsd using the following commands:
*as root*
$ pkg install ghc hs-cabal-install
*Change Path to
PATH="$PATH:/usr/local/elm/Elm-Platform/0.18/.cabal-sandbox/bin"*


$ curl
https://raw.githubusercontent.com/elm-lang/elm-platform/master/installers/BuildFromSource.hs >
BuildFromSource.hs


$ runhaskell BuildFromSource.hs 0.18


Any help would be appreciated.


Thks !

Hi!

Everytime someone has a problem with X is working on MacOS, but it is not
working on Linux, my intuition is: A file/folder is named in the wrong case.
HFS+, unlike most other file systems, doesn't make a difference between
lowercase and uppercase. If you look at your folder, its called "users",
while the module is using "Users".

Maybe this is just a dump guess and the problem you have cannot be solved
that easy :)

Thanks a lot Daniel !

That was indeed a lowercase/uppercase issue...

=> I've renamed the folder to meet the module name and all has been
perfectly compiled

I would recommend you to jump into slack (http://elmlang.herokuapp.com/)
next time. Such questions can be potentially answered much quicker there.
Folks, especially in the beginners channel, have helped me a lot already.
It is super friendly!
