Hi all. I'm compiling PETSc 3.7.3 on Fedora; the libraries are built in 4 different stages, each stage starting from a *clean PETSc source* directory:
petsc src
|
v
petsc src1 |--> serial libraries (link1)
petsc src2 |--> serial (64bit INTEGER) libraries (link2)
petsc src3 |--> OpenMPI libraries (link3)
petsc src4 |--> MPICH libraries (link4)

The resulting libraries look contain 'unused (strange) direct shared
library dependencies'. Like for serial libpetsc.so:
$ ldd -u /usr/lib64/libpetsc.so.3.7.3
Unused direct dependencies:
/lib64/libmetis.so.0
/lib64/libhwloc.so.5
/lib64/libhdf5.so.10
/lib64/libquadmath.so.0
/lib64/libstdc++.so.6
/lib64/libgomp.so.1
libmetis.so is (correctly?) activated with *--with-metis=1* option but
results unused.
libhwloc.so.5, libhdf5.so.10 and libstdc++.so shouldn't be linked.
Here you can find a full build log on Fedora 24 64bit:
https://copr-be.cloud.fedoraproject.org/results/sagitter/petsc/fedora-24-x86_64/00461492-petsc/build.log.gz
RPMs built are:

Do you have idea why this happens?
Regards.
