pyvisa-py not linking with linux-gpib #254

Open kdkirmse opened 4 years ago

kdkirmse commented 4 years ago

It looks like I have some form of library incompatibility between pyvisa-py and linux-gpib. I cannot get pyvisa-py to use linux-gpib

I have installed linux-gpib 4.3.3 R1916

python3 -m visa info output
