There might also be a misunderstanding given your first post, because I only use stack to provide those ghc (ghc-pkg, alex, happy) binaries, and I'm not managing the ghc source as a stack package; and what that means is that I don't have to run `stack exec --` to interact with build artifacts.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jan 26, 2017 at 8:05 PM, Alan & Kim Zimmerman <span dir="ltr"><<a href="mailto:alan.zimm@gmail.com" target="_blank">alan.zimm@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>FWIW, I use the docker image, as per <a href="https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Linux#Docker" target="_blank">https://ghc.haskell.org/trac/<wbr>ghc/wiki/Building/Preparation/<wbr>Linux#Docker</a>, where I have the invocation in a one-line script<span class="HOEnZb"><font color="#888888"><br><br></font></span></div><span class="HOEnZb"><font color="#888888">Alan<br></font></span></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On 26 January 2017 at 19:38, Phyx <span dir="ltr"><<a href="mailto:lonetiger@gmail.com" target="_blank">lonetiger@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p dir="ltr">But do you really want to do this? </p>
