<div dir="ltr"><div>Hey All,</div><div><br></div><div>I'm trying to install MPICH on a set of National Instruments myRIOs. They run the angstrom kernel. Currently when I run the configuration for the build it errors at the AR interface because the ar function is missing -r for replacement in archives. This is a busy box implementation of ar. It doesn't look like busy box has a new implementation. So i'm looking at two options avoiding the archiver if that is an option or download a new ar function. The myRIO uses a armv7a processor. </div>
<div><br></div><div>Can I get by with disabling the archiver interface? skiming readme looks like no option to do so</div><div>Can I disable the check on the archiver interface with --disable-ar interface?</div><div>Another ar function?</div>
