Incompatible processor?

[kb6nu]

I just installed Linux Mint on this Windows box and ran the Andy's Ham Radio script to install a bunch of ham radio software including Not1MM. When I tried running Not1MM from the application menu nothing happened, so I saw that you could run it from the command line using the command run_not1mm. When I do that, I get the error message:

Incompatible processor. The Qt build requires the following features: sse4.2 popcnt

I'm not sure what this means. Can I somehow get not1mm to run on this machine, or is the processor too old, or ???

Thanks,

Dan KB6NU

Hi Dan, Sorry you're having trouble. I'm not very familiar with Andy's or the run_not1mm script.
But the error you're seeing seems to be saying that the Qt6 GUI library needs that processor feature in order for it to run.

I'm not sure how Qt was built. But after applying some Google Fu, It looks like the sse4.2 popcnt thing is an optional compile flag.
Which is all well and good but I don't think you have the option to compile your own Qt stack on Andy's to omit this compile time flag.
I looked thru the build requirements documentation for Qt6 and it has no specific mention of a minimum processor spec required.
Back in the day I remember compiling C code, and the setup scripts tested what your setup was and turned on specific compile time flags if your hardware supported it. So my guess is Andy has a newer processor and the compiled binary reflects this.

I know my laptop is no spring chicken. It's a 2012 vintage ThinkPad T430 with an i5. Looks like support for sse4.2 first appeared in 2008.

Hope that helped.

Cheers, Mike K6GTE

Just for funzies you might try installing uv from Astral and see if you can run an instance of not1mm with uvx.
Worth a try.

curl -LsSf https://astral.sh/uv/install.sh | sh

then

uvx not1mm@latest

Thanks for the quick reply. Maybe I’ll try un-installing the Andy’s version and re-installing it. 73! Dan KB6NU

Tried that. Got the same error message. :( I guess I need to figure out what the deal is with Qt. 73! Dan KB6NU

Have you had any more thoughts about this? I thought maybe that Andy's Ham Radio Linux somehow screwed up my system, so I reloaded the OS and re-installed not1mm, but I'm still getting this error message. :(

No, I'm sorry Dan. I haven't found/seen anything to resolve your issue with Qt6/PyQt6.

Dan, I saw your blog post on this yesterday and I don't have an answer. I too am running a rather old computer, a Lenovo M73 with a Core i5 processor, etc. Installing using the uvx method recommended by Mike works flawlessly on Debian 12 (currently tagged as 'oldstable').

I will note that when using various package managers that uninstalling and installing again may or may not make any difference. For example, Debian's (Ubuntu's, Mint's, etc.) apt will not remove modified configuration files unless a package is explicitly purged. Other package managers may or may not behave similarly. What this means is that in the course of setting up or running a program, some files will be installed either to the system directory /etc or to one's home directory (depending on the type of package). The apt package manager will leave most files in the /etc directory unless told to purge them. Programs like Not1MM and even Qt will write files to a user's home directory but no package manager that I am aware of will remove those files so once written there by a program they have to be explicitly deleted by the user. This means that uninstalling and installing a package again will not do anything to files written in a user's home directory.

I would be curious, Dan, if you could install Linux Mint and then install Not1MM per its manual and see if it works.
