[petsc-dev] Investigation about 'unused direct shared library dependencies'

[Antonio Trande]

Thanks for your replies.
I have fixed almost entirely all unused dependencies.


petsc.x86_64: W: unused-direct-shlib-dependency
/usr/lib64/libpetsc.so.3.7.3 /lib64/libhdf5.so.10

petsc64.x86_64: W: unused-direct-shlib-dependency
/usr/lib64/libpetsc64.so.3.7.3 /lib64/libhdf5.so.10

As Satish said, 'hdf5' is required by 'cgns' at building time.
Like libptscotcherr/libscotcherror, i guess, are required for Scotch.
Remain an unused link of 'scalapack' in the MPI builds:

petsc-mpich.x86_64: W: unused-direct-shlib-dependency
/usr/lib64/mpich/lib/libpetsc.so.3.7.3
/usr/lib64/mpich/lib/libscalapack.so.2
petsc-mpich.x86_64: W: unused-direct-shlib-dependency
/usr/lib64/mpich/lib/libpetsc.so.3.7.3
/usr/lib64/mpich/lib/libptscotcherr.so.0
petsc-mpich.x86_64: W: unused-direct-shlib-dependency
/usr/lib64/mpich/lib/libpetsc.so.3.7.3
/usr/lib64/mpich/lib/libscotcherr.so.0

petsc-openmpi.x86_64: W: unused-direct-shlib-dependency
/usr/lib64/openmpi/lib/libpetsc.so.3.7.3
/usr/lib64/openmpi/lib/libscalapack.so.2
petsc-openmpi.x86_64: W: unused-direct-shlib-dependency
/usr/lib64/openmpi/lib/libpetsc.so.3.7.3
/usr/lib64/openmpi/lib/libptscotcherr.so.0
petsc-openmpi.x86_64: W: unused-direct-shlib-dependency
/usr/lib64/openmpi/lib/libpetsc.so.3.7.3
/usr/lib64/openmpi/lib/libscotcherr.so.0

'scalapck' is configured with:

 --with-scalapack=1 \
 --with-scalapack-lib="-L/usr/lib(64)/openmpi/lib -lscalapack" \
 --with-scalapck-include=/usr/include/openmpi-%_arch \
