Compile for intel and Amd (question) #200

Closed alphafox02 closed 4 years ago

alphafox02 commented 4 years ago

Is there a flag or option I can add when compiling that’ll allow the installed liquid-dsp to run in both intel and amd? I’ve not figured out the exact issue and I’m sure this is a weird request, but if I compile liquid-dsp as it states on your GitHub page to use alongside cubicsdr it works fine on my intel machine. If I take out the hard drive and stick it in a Amd based machine, start up cubicsdr I get failures with liquid-dsp. I know that’s not a lot of detail, but I will say if I go into the liquid-dsp folder make uninstall/clean and rerun the instal steps everything is then fine with it.

I’m assuming this has something to do with me first compiling on intel and then moving to amd.

I don't think so. While AMD and Intel share the X86_64 architecture, running a program (or linking to a library) compiled for a different system is going to have unexpected results, and will most certainly not work. You'd want to either cross-compile for the target system, or just build natively.

Hi. I found that compiling as directions state on the github page results as I mentioned above. What I end up having to do in the Amd machine is go back in the liquid-dsp source folder and run make uninstall and or make clean followed by all the steps to compile it from scratch. Everything is then fine on the Amd machine. If I understand what you are saying the standard steps on the liquid dsp git page will not allow me to simply move from Intel to Amd without rebuilding it.
