Hello everyone
I would like to control some data acquisition equipment so I installed the library from the GitHub repository of the manufacturer (
https://github.com/mccdaq/uldaq). After building the project as described on the repository, I get a symbol lookup error when I try to run one of the provided examples (`AIn` in this case):
Quote:
./AIn
Found 1 DAQ device(s)
[0] USB-1608GX: (020D2FF3)
Connecting to device USB-1608GX - please wait ...
/home/dvarx/Downloads/libuldaq-1.2.1/examples/.libs/AIn: symbol lookup error: /home/dvarx/Downloads/libuldaq-1.2.1/src/.libs/libuldaq.so.1: undefined symbol: libusb_has_capability

When I run the same program as superuser, no errors occur and everything seems to work fine. I did install the device rules file with the following rule:
Quote:
|
SUBSYSTEM=="usb", ATTR{idVendor}=="09db", ATTR{idProduct}=="0135", GROUP="adm", MODE="0666"
|
which corresponds to the device I want to control:

Does anyone have an idea how I could debug this issue?
