CentOS 5.11: Illegal instruction

[noharm]

Hi All,

I’m trying to install the latest NoMachine free version on a CentOS5.11 virtual machine (openstack KVM guest). But the installer completes with errors and I can’t get the binaries to run. On a CentOS6 guest I have no problems at all, but need the CentOS5 platform for compatibility reasons of other old software.

Any insights would be appreciated.

Regards, Harm

I think I was able to trace the issue to a call from /usr/NX/lib/libcrypto.so

[root@nomachine-test ~]# ulimit -c unlimited
[root@nomachine-test ~]# sysctl -w kernel.core_uses_pid=1
kernel.core_uses_pid = 1
[root@nomachine-test ~]# /etc/NX/nxserver –start
Illegal instruction (core dumped)

Hi.

We couldn’t reproduce problem on different virtual machines with CentOS 5.11. But we would like to look closer to this issue.We couldn’t find CentOS 5 image on openstack sources (https://docs.openstack.org/image-guide/obtain-images.html). Can you tell us how you prepared the image with CentOS 5? Send a link with instructions.
