<p>Dear Barry,</p>
<p>Currently we are testing compilation on arm on a raspberry pi, where we include a locally compiled onetbb2021.4. The distributed binary package includes a scip compiled with soplex and papilo.<br></p>
<p>As far as I know there are no immediate plans for getting a mac machine with the new architecture.</p>
<p>For improving the compilation, let's continue the discussion privately. Please send me logfile containing the error(s) and we can check it.<br></p>
<p>Best,<br>
Franziska<br></p>

<div>Dear Barry,</div>

<div>I think PaPILO depends on libraries that are not cross-platform, it will be a mid-term goal to make it compile everywhere. In the meantime for Mac ARM, compiling with PaPILO off should work?</div>
<div><br></div>
<div>Let us know if it doens't.</div>

<br>
<span style="font-family:"Helvetica Neue"">I wonder if there are any plans to provide binary packages for the ARM architecture? The latest v7.0.3 source code does not cleanly compile on a new ARM64v8 MacBook Pro – there are some external dependencies such as “catch” in papilo that are missing upstream changes for ARM support. I managed to get it to compile by updating that and disabling some things but there were a number of warnings. `make test` successfully passes 1361 tests.</span><br>
<br>
<span style="font-family:"Helvetica Neue"">Is this something that there is any plans to provide official binaries for? I would be happy to help in any way I can. With Apple no longer selling Intel machines, this is likely to become a growing demand I would expect. Many thanks in advance, and thank you for all the work that has gone into the SCIP suite so far.</span><br>
