Hi there,

I am trying to run a singularity container on a CentOS7 host, which 
contains an application with Qt5 dependencies.

I am experiencing an error where |libQt5Core.so.5| can not be used 
because of an incompatibility with the linux kernel version for CentOS7:

|uname -r 3.10.0-1160.76.1.el7.x86_64 |

The error given is: |
error while loading shared libraries: libQt5Core.so.5: cannot open 
shared object file: No such file or directory|.

Searching online, various posts (e.g. 
<https://askubuntu.com/a/1163268/1041180>) conclude the solution is to 
execute the following command in order to impose compatibility with 
older kernels:

|strip --remove-section=.note.ABI-tag 
/usr/lib/x86_64-linux-gnu/libQt5Core.so.5|

However executing the command returns the error: |strip: 
/usr/lib/x86_64-linux-gnu/libQt5Core.so.5: could not create temporary 
file to hold stripped copy: cause of error unknown|

I have confirmed:

  * the container works on systems with a newer kernel
  * I am running the container with the |--writable| flag, and as |sudo|
  * I have the correct path:
      o

        |whereis libQt5Core.so.5||
        libQt5Core.so.5: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5|

I am at a dead end as to why the strip command is not working. I have 
been unable to find a solution online.  As strip is a part of the 
binutils suite, I was hoping that someone might be able to point me 
towards a solution, or at least a line of investigation?

Sincerest thanks in advance!

Cheers,
Paul
