Need 64-bit version of mkl_link_tool in the DevCloud

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 .:-)

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?

Thank you for your reply. I

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 :-)

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

Thanks, András
