<p>I use to compile mpich <span style="font-family:Calibri,Helvetica,sans-serif,EmojiFont,"Apple Color Emoji","Segoe UI Emoji",NotoColorEmoji,"Segoe UI Symbol","Android Emoji",EmojiSymbols; font-size:16px">versions 3.4,x, 4.1.x, and 4.2.x</span> configured with
this option (--with-hcoll=) in the past without any problems. It looks like some recent changes in the related files introduced a problem that slip into 4.3.0 and makes compilation impossible.<br>
<br>
Could it be fixed ? Or could the --with-hcoll option be removed if it is no longer relevant (I guess that if we use ch4:ucx, ucx may itself use hcoll internally to optimize collective operations when running on hierarchical environment) ?<br>
<br>
Here are some details:<br>
