<div>Dear mvapich team,</div>
<div><br>
</div>
<div>There is a minor issue with the documentation at this location:</div>
<div><br>
</div>
<div><a href="https://mvapich.cse.ohio-state.edu/userguide/userguide_spack/" data-auth="NotApplicable">https://mvapich.cse.ohio-state.edu/userguide/userguide_spack/</a></div>
<div><br>
</div>
<div>Can you please update the spack install instructions with this minor change? </div>
<div><br>
</div>
<div>Basically spack requires a specific version for externals, so the "spec" line needs to have a specific version as shown below:</div>
<div><br>
</div>
<div><font face="monospace" size="4"> rdma-core:<br>
buildable: False<br>
externals:<br>
- spec: rdma-core<b><font color="#ff0000">@52.0</font></b><br>
prefix: /usr<br>
</font></div>
<div><br>
</div>
<div>Not sure if there is a better way but what I did was to first try to run the "spack spec ..." command without the above section and it shows which version spack is expecting and added that version in the packages.yaml file as mentioned above.</div>
<div><br>
</div>
<div>Thank you!</div>
