Re: Link Error with DAOS 1.0

Nabarro, Tom
 

There have been some fixes in master for build issues with ubuntu 20.04 (specifically for spdk, ipmctl and I think hwloc). Can you try building from master?

This small patch gets me past that error:

 

jvolivie-desk1:[~/daos_1.0]$ git diff

But then it runs into an issue with hwloc.

It looks like hwloc version 1.5 which should work but perhaps there is something new on Ubuntu 20.04 that we only resolved on master.

Hi Archie,

 

I don’t know if 1.0 has been tried with Ubuntu 20.04 though it does work with 18.04.   I will give it a try locally and see what I can find out.

Sorry for not having that:
