undefined symbol: libusb_get_port_number

[modrobert]

On Ubuntu 16.04.5 LTS configuring and compiling works fine but when running 'rkdeveloptool' I get the following error:

rkdeveloptool: symbol lookup error: rkdeveloptool: undefined symbol: libusb_get_port_number

After checking libusb-1.0...

$ nm -D /usr/lib/libusb-1.0.so.0.0.0 | grep get_

As you can see libusb_get_port_number() is missing in libusb-1.0.

The following fix using libusb_get_device_address() instead worked for me:

$ diff RKScan.cpp.original RKScan.cpp.fix
262c262,263
<                       desc.uiLocationID += libusb_get_port_number(dev); 
---
>                       // desc.uiLocationID += libusb_get_port_number(dev); 
>                       desc.uiLocationID += libusb_get_device_address(dev);
