Need 64-bit version of mkl_link_tool in the DevCloud

[Andras_A_]

I have a project on the DevCloud that uses MKL and is built with CMake. For convenience, CMake invokes `mkl_link_tool` to construct the link line. However, `mkl_link_tool` happens to be a 32-bit executable:

/glob/development-tools/versions/intel-parallel-studio/compilers_and_libraries_2019.3.199/linux$ file mkl/tools/mkl_link_tool
mkl/tools/mkl_link_tool: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-, for GNU/Linux 2.6.18, BuildID[sha1]=ec312866645ce227a0fd3b0aeabe20b1c9d7ba42, not stripped

and Ubuntu does not let it run. `bash` gives a very misleading error message, saying that the file could not be found.

The cure is to install the 32-bit compatibility layer package:

`sudo apt-get install lib32stdc++6`

but hey, I have no sudo privileges on the DevCloud :-)

Is there a quick workaround at the user level?

BTW, it's high time for `mkl_link_tool` grew up and gained an additional set of 32 bits which I am sure it deserves .:-)

Cheers, AA

yes, you are right, this is a 32-bit routine. I am not sure about the workaround with this case...only manually added the need libraries but this is not what you like to see as I guess.  Could you submit the official Feature Request to the Intel Online Service Center?

[Andras_A_]

Thank you for your reply. I will certainly submit a Feature Request as suggested.

However, a quick fix is needed ASAP. Would it be possible that a sysadmin installs the Ubuntu 32-bit compatibility layer on the DevCloud in the meantime? As far as I can tell the following commands are needed:

sudo dpkg --add-architecture i386
sudo apt update
sudo apt install libc6:i386

...but I leave it to the experts to figure out the details :-)

Many thanks, András

Please note that MKL 2020 update 1 has 32bit and 64 bit binaries for the mkl_link_tool already.  They are found in mkl/tools/mkl_link_tool/{ia32/intel64} folders.

Thank you, but that does not help me as I cannot install that on the DevCloud either :-)

...and that's going to be the correct solution for this problem on the DevCloud. Many thanks!

mkl v. 2020 u1 has been released.

Excellent news! Now some good soul should install it on the DevCloud... :-)

Thanks, András
