Hi Satish,
I just discovered that PETSc 3.16.4 fails to link against the
latest AMD
BLIS and LibFLAME libraries on a Linux box.
-------------------------------------------------------------------------------
You set a value for --with-blas-lib=<lib> and
--with-lapack-lib=<lib>,
but ['/opt/amd/amd-blis-3.1.0/lib/lp64/libblis.a'] and
['/opt/amd/amd-libflame-3.1.0/lib/lp64/libflame.a'] cannot be used
*******************************************************************************
My previous experience with 3.9.4 on the same system was fully
successful. Looking in the configure logs (attached) reveals small
difference in the linking compared to 3.9.4
Could you please make a guess what went wrong?
Down in the log I see:
/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):
Thanks Matt, I'll try.
Did the gfortran library move or get upgraded?
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.
Best,
Anton
Thanks,
Matt
Best regards,
Anton
