<div dir="auto">I assume stack-based builds are still broken for PPC, as well as Intel builds on 10.6.8, but I will try to find time to work on fixing it. Ken kindly shared his work on GHC for Snow Leopard, but it is for x86 (and not in Macports).<br>
<br>
If anyone is good at cross-compiling, please ping me. We need to first build the latest GHC on 10.6.8 Intel and then cross-compile GHC for PPC.</div>

<blockquote type="cite" style="border-left-color: grey; border-left-width: thin; border-left-style: solid; margin: 5px 5px;padding-left: 10px;">I recently added legacy-based support to pandoc, but I’m not sure that the code I used is working. I’ll issue a revised PR based on any feedback and use a working version for other GHC-based projects.

<div>stack-based stack builds work all the way back to Snow Leopard: https://ports.macports.org/port/stack/details/. I’d expect the same of pandoc, but it only builds back to Sierra: <a href="https://ports.macports.org/port/pandoc/details/">https://ports.macports.org/port/pandoc/details/</a></div>
</div>
</div>
<div><br></div>
<div>Is anyone able to suggest profile code that will accomplish this? Is this related to the design choice to use a the port variant +stack to specify the build tool?</div>
