<br>
I just discovered that PETSc 3.16.4 fails to link against
the latest AMD <br>
BLIS and LibFLAME libraries on a Linux box.<br>
<br>
-------------------------------------------------------------------------------<br>
You set a value for --with-blas-lib=<lib> and
--with-lapack-lib=<lib>, <br>
but ['/opt/amd/amd-blis-3.1.0/lib/lp64/libblis.a'] and <br>
['/opt/amd/amd-libflame-3.1.0/lib/lp64/libflame.a'] cannot
be used<br>
*******************************************************************************<br>
<br>
My previous experience with 3.9.4 on the same system was
fully <br>
successful. Looking in the configure logs (attached) reveals
small <br>
difference in the linking compared to 3.9.4<br>
<br>
Could you please make a guess what went wrong?<br>

<p>Thanks Matt, I'll try.<br>

<p>Not at all. I have configured 3.9.4 just now to make a test, and
it perfectly finds all the libraries. So there must be something
that 3.16.4 does differently. <br>
