Cannot build a site without archive

[qaristote]

I'm trying out Hakyll and want to build a single webpage with no blog posts nor archives. I thus deleted every instance of these that appears in the initial site:

$ ls
css  images  index.html  my-site.cabal  site.hs  templates

$ ls templates
default.html

$ cat index.html
---
title: Home
---

<h2>Welcome</h2>

<img src="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/images/haskell-logo.png" style="float: right; margin: 10px;" />

<p>Welcome to my blog!</p>

<p>I've reproduced a list of recent posts here for your reading pleasure:</p>

$ cat site.hs
--------------------------------------------------------------------------------
{-# LANGUAGE OverloadedStrings #-}
import           Data.Monoid (mappend)
import           Hakyll


--------------------------------------------------------------------------------
main :: IO ()
main = hakyll $ do
    match "images/*" $ do
        route   idRoute
        compile copyFileCompiler

    match "css/*" $ do
        route   idRoute
        compile compressCssCompiler

    match "index.html" $ do
        route idRoute
        compile copyFileCompiler
--------------------------------------------------------------------------------

$ cat templates/default.html
...
        <header>
            <div class="logo">
                <a href="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/">My Hakyll Blog</a>
            </div>
            <nav>
                <a href="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/">Home</a>
            </nav>
        </header>
...

But somehow Hakyll still insists on building archive.html:

$ cabal build
...
$ site build -v

Why is that ? What I am supposed to do if I don't want to build a blog ?

This seems weird -- maybe cabal build did not put the output in ./site? Could you try again using e.g. cabal run site?

[qaristote]

Yes that works thank you ! Note that site build still doesn't work even after a successful cabal run site build though.

@qaristote You have to re-run cabal new-install every time you change the Haskell code. If you don't do that, invocations of site build would run an old version of the binary. You can do cabal new-install && site build if you want, but cabal run site build achieves pretty much the same result without installing the binary into ~/.cabal/bin.

Oh ok I get it now, thanks :)
