<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></blockquote><div><br></div><div>Down in the log I see:</div><div><br></div><div>/usr/bin/ld: warning: libgfortran.so.5, needed by /opt/amd/amd-libflame-3.1.0/lib/lp64/libflame.so, not found (try using -rpath or -rpath-link):<br></div><div><br></div><div>Did the gfortran library move or get upgraded?</div><div><br></div><div> Thanks,</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
