Illegal Instruction (core dumped) Linux Mint 21.1 & GQRX App - error-handling

I'm a total noob to Linux, running Linux Mint 21.1 on an old AMD Phenom 2 x4 955 machine. I'm trying to run an app called GQRX-SDR for a USB software defined radio (RTL-SDR) & it won't open from "All Applications". From Terminal it simply gives
"Illegal Instruction (Core Dumped)"
Does anyone have any suggestions how to fix this? Please bear in mind I'm brand new to Linux & I don't understand any of the posts I've read so any suggestions would have to be really detailed & spelt out.
Thanks.
Installed Linux Mint 21.1 & GQRX on the fresh install. No other changes.

Installation of Kinect on Mac OS Sierra

I have a Kinect 1414 and a MacBook Pro which has mac os sierra on it. I am trying to install the necessary things to run a sample in my mac. In order to do that, I strictly followed the steps shown in here. After completing each step, when I run the Sample-PointViewer, I am getting this output:
1628 INFO New log started on 2017-02-11 00:17:31
1709 INFO OpenNI version is 1.5.7 (Build 10)-MacOSX (Nov 12 2013 13:39:54)
1715 INFO --- Filter Info --- Minimum Severity: UNKNOWN
One or more of the following nodes could not be enumerated:
I am not sure if it is an important thing but I also noticed that even if I disconnect Kinect from mac, it gives the same output.
If anyone can help me, I will be really happy.
Thanks in advance.

Why would Objective-C require a post-2010 Mac?

I'm thinking of signing up for the Objective-C Crash Course on Udemy but the requirement is a Mac after 2010.
I have an early 2009 with 2 x 3.32 GHz Quad-Core Intel Xeon 64 GB 1066 MHz DDR3 ECC & ssHD happily running El Capitan v10.11.6 & running Xcode beta 8.5
Is there something that I'm missing? Is it a hardware thing?
(Please forgive me if this is a really dumb question but I'm a newb in diapers.)
Udemy may have other reasons for requiring a more recent Mac that is specific to their course.. If you can run El Capitan, you can install the latest Xcode and can use it to learn Objective-C. I would suggest ignoring the requirement for the course until if and when it becomes clear why it's in place.

How do I manually configure NI Visa on linux

I'm trying to get the National Instruments Visa library (without Labview) working on a Redhat Enterprise Linux 6.7 PC. It comes with some configuration utilities (NIvisaic & visaconf) to find and setup the instruments but after a week of trying we've given up trying to get them to run. I know from windows it's just a configuration text file visaconf.ini but I don't know where to put it or if it's the same file & format for linux. Bottom line, how do I manually configure NI Visa in Linux ?
Why not use the PyVISA library?

Issue Installing Elastix 4.0 via Bootable USB - CentOS7 Error

Goal
I was attempting to install Elastix 4.0 on a home PC via a Bootable USB, but never had any luck getting it to install past the CentOS7 part (it kept giving me a "Warning: /dev/root does not exist" error).
What I've Tried
My main PC is Windows 10 Pro, so after downloading the latest Elastix 4.0 .iso from "http://www.elastix.com/en/downloads/" (Elastix-4.0.74-Stable-x86_64-bin-10Feb2016.iso) I used UNetbootin to create my Bootable USB for Elastix 4.0. I put the now Bootable USB into the PC I want to put Elastix 4.0 on and started it up.
It gave me the "Install Elastix 4" menu, so I hit enter and waited. Then the install proceeded to do its checks for CentOS7, but ended up getting stuck and gave me an error message "dracut-initqueue[580]: Warning: Could not boot." and "Warning: /dev/root does not exist".
This is where I am stuck and cannot proceed.
EDIT #1: I signed up for the Elastix forms, and someone else also had this issue. They said they downloaded the .iso and used Rufus to make a Bootable USB, and then booted the installation using the Troubleshooting -> Install CentOS 7 using Basic Graphics ... but according to them, that apparently corrupted something else and then they opted to just use a DVD.
EDIT #2: I tested this, and making a Bootable DVD of the .iso does work great for local machines. Installing it via a VM also seems to work without hassle. As a personal goal, I would like to get this working via a Bootable USB.
Research
I did some research but a lot of the solutions I've noticed are using the dd command in Linux to make a Bootable USB for just CentOS7 because it is (was?) known that UNetbootin did not properly make a Bootable USB for CentOS7, and I can't seem to find anything that would assist in making the Elastix 4.0 .iso work properly via a Bootable USB. I did try other tools such as Rufus 2.7, Win32 Disk Imager, ISO2USB, and dd for Windows, though most rendered my USB not bootable at all (Rufus worked OK, but still got stuck at the CentOS7 part). Also, installing via a CD/DVD is not ideal, as I have no CD/DVD drive (and I want to see if I can get this working via a Bootable USB drive).
There seem to be a few guides out there for trying to create a Bootable USB for Elastix 2.x, but nothing for Elastix 4.0. Reviewing those, it looks like the guides reference some files that do not exist in the new .iso (ex: ks_default.cfg). Still, my issue pertains mainly to the CentOS7 error I'm getting so I don't think this is related.
Any assistance with this is appreciated, and if you require more information from my end just let me know. I'm willing to try / re-try anything.
Thank you in advance.

Look for this line, but it may change:
append initrd=initrd.img inst.stage2=hd:LABEL=CentOS\x207\x20x86_64 inst.ks=cdrom:/dev/cdrom:/ks/anaconda-ks.cfg quiet
Change it to:
append initrd=initrd.img inst.stage2=hd:LABEL=CentOS\x207\x20x86_64 inst.ks=sdb1:/dev/sdb1:/ks/anaconda-ks.cfg quiet
Hi there i solve this problem 80%.
i did some manual change at line:
inst.ks=cdrom:/dev/cdrom:/ks/anaconda-ks.cfg quiet
Mine:
inst.ks=scsi:/dev/sdb1:/ks/anaconda-ks.cfg quiet
hd is not recogniced by Centos7.
made my usb bootable with rufus 2.9
then open isolinux.cfg with notepad++
just change the line
inst.ks=hd:sdb1:/ks/anaconda-ks.cfg quiet
where sdb1 used to say cdrom

Installing Curl IDE/RTE on AMD processors

Trying to move my development environment to Linux. And new to Curl. Can't get it to install the IDE & RTE packages on an AMD HP PC running Ubuntu x64. I tried to install the Debian package via the package installer and get "Error: Wrong architecture - i386". Tried using the --force-architecture switch but it errors out.
I'm assuming Curl IDE will just run under Intel processors? Anyone have any luck with this issue and can advise?
It's been a while since I ran linux, but try looking for the x64 version. There are also x64 to x86 compatibility libraries available that should make 32 bit programs work for most situations.
The ubuntu forums are a much better place for this question, however.
