I'm running on an i86 processor using Ubuntu, works well! Have you tried to build and run it on an Arm-based M1/M2 Mac by any chance? Guessing it might be tough to get the FFT and other libs working.

I think I made it run on Raspberry pi 3B+ before, which has an aged Broadcom ARM CPU.

I would like to ask if there is a problem with the carrier phase observations in the .obs file? When I input the base station and rover files, I can normally aquisition, track, and PVT. However, when I input the output .obs file into RTKlib for differential processing, the positioning results are all single point solutions, and I cannot obtain a fixed solution.
