            <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>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>
