Perdix AI on Linux

[Dirk Hohndel]

Hi Linus,

Trying to download from the Perdix AI on Linux. Running on an oldish Thinkpad
with the USB BT 4.0 dongle that you recommended.


$ ldd subsurface | grep Qt5Network
	libQt5Network.so.5 => /home/hohndel/Qt5.9.0/5.9/gcc_64/lib/libQt5Network.so.5 (0x00007f6f69dc8000)

This is the stock Qt 5.9 as downloaded from qt.io

It scans and finds the Petrel AI just fine. Download attempt results in:

Any ideas?
