For those interested, I put an ebuild of mkl version 8.0.1.006 on the overlay (http://gentooscience.org). Intel MKL uses quite a lot of resources to install, so be aware. The ebuild was redone from scratch and is still in early stages, but it seems to work. It is non interactive, and avoids installing rpm (only rpm2targz). Anyone willing to help is more than welcome!

Well I did try to use the rpm eclass without success, like the icc/ifc ebuilds do. The rpm created from the big install does not look very kosher, with rpmoffset and cpio failing to extract files. Using the full app-arch/rpm and associated database bring too many polluting dependencies. If anyone has more experience dealing with intel rpms, please help. BTW, I emailed Intel support for existing non-rpm dependent versions of mkl and ipp. Their response was they are working on a new install, which should do the job.
I reworked the ebuild significantly if anyone wants to give a try. I insisted and ended up using rpm_unpack, thanks spyderous. News are fortran95 implementation, some scripts to deal with the blas-config/eselect stuff, and a lot of other changes. There is a couple things which still need work: eselect does not show the mkl implementation, even after a scan. Also, right now the chosen solution to make it work for gentoo-like virtuals is merging the libs into one big library, through a rather ugly process. I would need libtool and eselect experts to give it a look. Also, it could benefit optimization with a cpu detection command (p3,p4,p4 with sse3,etc...). Is there anything wrong grep'ed /proc/cpuinfo for this?

Yes, because that breaks binary packages moved to different machines; also, cpuinfo formatting can be very unreliable. Can you use CFLAGS for this? Perhaps you could clear up exactly what you want to do with the cpu info.
(In reply to comment #6) > cpuinfo formatting can be very unreliable. Can you use CFLAGS for this? Perhaps > you could clear up exactly what you want to do with the cpu info. The cpu detection is needed to create a optimized kernel blas implementation. MKL comes with (e.g. x86) a libmkl.so as a core kernel, then one has to choose among libmkl_p3.so, libmkl_p4.so or libmkl_p4e.so depending on your processor. To make a full blas implemention, my idea was to create a libblas.so, merging the proper libs according to the cpu info. I updated the ebuild using the CFLAGS parsing option, but the list of parsed flags is certainly far from complete. Now anyone has an idea how to merge .so libs on a portable way, or has a more clever idea to use mkl as one of the blas/lapack virtual?
(In reply to comment #7) It turns out to be a reasonably bad idea, creating extra huge libraries. To go further into this ebuild, I would need some help regarding eselect. Of what I see in /usr/share/eselect/modules/{blas,lapack}.eselect, MKL is in, but hardcoded for version 7.2, which is neither in portage nor in bugs entries. Is the idea of eselect {blas,lapack} not only to select the library but also to show compilation flags, as a full replacement of {blas,lapack}-config? If yes, I can not see the option. MKL could really benefit of just showing compilation or link flags, properly selecting the CPU and threadings, instead of merging and re-installing the libraries.

Hi, Updates from the gentooscience overlay: - simple bump to 8.0.2.004 for the standard mkl - bump to 8.1.014. This mkl version is available when registering to premier.intel.com. Intel fixed a number of installation bugs, and consequently mkl ebuild changed a lot. This last ebuild doesn't provide mkl as a blas/lapack virtual yet, therefore much easier. It only installs mkl and update environment variables. Also note this new mkl provides a fftw (static libs only) implementation. Sebastien
There is no ebuild for mkl-8.1.1.004.
Created attachment 102112 [details] mkl-8.1.1.004 ebuild Here you are one ebuild for mkl 8.1.1.004, which is a slightly changed version of mkl-8.1.014.ebuild, in order to fix problems with the Intel mkl installer.
I'll try to bump this soon, I've been doing other Intel stuff yesterday.
I updated the mkl to version 9.0.018 in the main tree. Once again, intel had changed the installation process. I will try to support this version. Packaging the mkl is quite involved. As a remark, if Intel continues to grow their binary blob (it is now up to 400Mb), as long as modifying the installation process, I doubt the work of packaging it is worth it.
