You should probably be talking to Intel who produces these .deb files, and/or to the GAMESS people. This is a simple convenience repo with a helper script that was once useful to me. It is in no way official or affiliated with Intel.

Ah, and it now automatically redefines BLAS/LAPACK during the package install:

Setting MKL as default BLAS/LAPACK implementation as requested.
update-alternatives: using /usr/lib/x86_64-linux-gnu/libmkl_rt.so to provide /usr/lib/x86_64-linux-gnu/libblas.so (libblas.so-x86_64-linux-gnu) in manual mode
update-alternatives: using /usr/lib/x86_64-linux-gnu/libmkl_rt.so to provide /usr/lib/x86_64-linux-gnu/liblapack.so (liblapack.so-x86_64-linux-gnu) in manual mode
update-alternatives: using /usr/lib/x86_64-linux-gnu/libmkl_rt.so to provide /usr/lib/x86_64-linux-gnu/libblas64.so (libblas64.so-x86_64-linux-gnu) in manual mode
update-alternatives: using /usr/lib/x86_64-linux-gnu/libmkl_rt.so to provide /usr/lib/x86_64-linux-gnu/liblapack64.so (liblapack64.so-x86_64-linux-gnu) in manual mode

This is during the run of:

sudo apt-get install intel-mkl-full

[eddelbuettel]

So we no longer need to set up the file /etc/ld.so.conf.d/mkl.conf ? Good.

It appears so. It's odd that they made such a major change in the same major version.

[eddelbuettel]

So short of a more formal PR (no need really) should I just comment out lines 27 to 30? Would you be able to test and verify?

[stas00]

I was hoping you'd do an install of the latest release at some point in the future and see what needs to be changed. I haven't used the previous setup, so I have no point of reference. I only meant to indicate these changes in this issue.

It turns out that the quantum mechanics code GAMESS looks for the mkl libraries in the /opt/intel/ tree, and that is now broken. Intel says that the mkl libraries are installed in /opt/intel/...
While I can see the possible benefit of also having them in the other locations, I think it should not also break what would normally be expected from packages that can use it. Could the transition not keep both with a link from the /opt tree to the standard ones?

Ah, thank you for the clarification.
