The applicative-numbers package [1] provides an include file.  With ghci, the include file isn&#39;t being found, though with cabal+ghc it is found.<br><br>My test source is just two lines:<br><br>{-# LANGUAGE CPP #-}<br>#include &quot;ApplicativeNumeric-inc.hs&quot;<br>
<br>I&#39;d sure appreciate it if someone could take a look at the .cabal file [2] and tell me if I&#39;m doing something wrong.  And/or point me to one or more working examples of cabal packages that export include files that are then findable via ghci.<br>
