[petsc-users] Ignoring PETSC_ARCH for make check?

[san.temporal at gmail.com]

Hi all,

I have just successfully compiled 3.13.0. But with install this is what I
get

    $ make PETSC_DIR=/home/santiago/Documents/installers/petsc/petsc-3.13.0
PETSC_ARCH=arch-linux2-c-opt install
    *** Using
PETSC_DIR=/home/santiago/Documents/installers/petsc/petsc-3.13.0
PETSC_ARCH=arch-linux2-c-opt ***
    *** Installing PETSc at prefix location: /home/santiago/usr/local  ***
    ====================================
    Install complete.
    Now to check if the libraries are working do (in current directory):
    make PETSC_DIR=/home/santiago/usr/local PETSC_ARCH="" check
    ====================================
    /usr/bin/make  --no-print-directory -f makefile
PETSC_ARCH=arch-linux2-c-opt
PETSC_DIR=/home/santiago/Documents/installers/petsc/petsc-3.13.0
mpi4py-install petsc4py-install libmesh-install mfem-install slepc-install
hpddm-install amrex-install
    make[2]: Nothing to be done for 'mpi4py-install'.
    make[2]: Nothing to be done for 'petsc4py-install'.
    make[2]: Nothing to be done for 'libmesh-install'.
    make[2]: Nothing to be done for 'mfem-install'.
    make[2]: Nothing to be done for 'slepc-install'.
    make[2]: Nothing to be done for 'hpddm-install'.
    make[2]: Nothing to be done for 'amrex-install'.

What is strange to me is that I am instructed to execute a line with
PETSC_ARCH=", while my environment has PETSC_ARCH=arch-linux2-c-opt
Why is that?

PS: The same happened to me with various other compilations I have just
tested, with 3.9, 3.10, 3.11, 3.12

PS2: I do not recall seeing this ever before, although I may have missed
it/forgotten.

Thanks in advance,
Santiago
