Can't get Waveforms SDK to work on Linux (Arch and Ubuntu 22.04 VM)

[Gen]

Hi,

I can't get the Waveforms SDK working. The Waveforms application works fine, and the dwfcmd command as well.

I have tried the AUR packages (waveforms and adept runtime) on Archlinux, and then made a fresh Ubuntu VM (quemu) (from iso: ubuntu-22.04.1-desktop-amd64.iso) where I installed digilent.adept.runtime_2.26.1-amd64.deb and digilent.waveforms_3.19.5_amd64.deb downloaded from the digilent website.

The Python examples, or my own Python scripts using the SDK always throw an error of an undefined symbol.

 File "/usr/share/digilent/waveforms/samples/py/Device_Enumeration.py", line 19, in <module>
    dwf = cdll.LoadLibrary("libdwf.so")
  File "/usr/lib/python3.10/ctypes/__init__.py", line 452, in LoadLibrary
    return self._dlltype(name)
  File "/usr/lib/python3.10/ctypes/__init__.py", line 374, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: /lib/libdwf.so: undefined symbol: DmgtConfigureFPGA

The nm command also says that there are no symbols in /lib/libdwf.so or /usr/lib/libdwf.so. Shouldn't there be some?

I also can't build any C examples, or the dwfcmd command. (I can run the included one, but not compile it myself)

 

When building the dwfcmd with: sudo g++ -ldwf dwfcmd.cpp -o out I get endless warnings and hidden somewhere in them is one error:

dwfcmd.cpp: In function ‘bool FAnalogOutPlay(HDWF, int, int)’:
dwfcmd.cpp:1734:17: error: ordered comparison of pointer with integer zero (‘char*’ and ‘int’)
 1734 |         if(szRun<=0){

after commenting out the code that causes this error, ld complains about not finding symbols.

A bunch more of undefined reference to ...
/usr/bin/ld: dwfcmd.cpp:(.text+0xcce7): undefined reference to `FDwfDigitalIOOutputGet'
/usr/bin/ld: dwfcmd.cpp:(.text+0xcd9e): undefined reference to `FDwfDigitalIOStatus'

collect2: error: ld returned 1 exit status

libusb-1.0.so.0 is present on both Arch and Ubuntu. as verified with ldconfig -p | grep usb.

What could be the problem here?

Hi @Gen

Oh, I did read through that thread, but thought that because I already had adept installed, it must be a different problem for me. I didn't see that those links had a newer version. 🤦‍♂️

2.27.7 works without problems!! (on Arch and Ubuntu)

Thanks for the extremely fast response.
