Empty list of usb device, nxusb cannot be compiled because of missing relocs_32

[jeremy.fix]

Hello,

I’m facing issues with some clients (but not all) trying to connect to a NoMachine server.

When we try to connect a USB device, the list is always empty. I tried with another client that I know to work, trying to share the same USB device with the same NoMachine server, and I was able to share the device.

My initial guess was that maybe nxusb.ko is required and not loaded on the client because not in the correct format. But actually, if I try to

cd /usr/NX/share/src/nxusb && make -f Makefile

I get :

make -C /lib/modules/5.3.0-62-generic/build M=
make[1]: Entering directory ‘/usr/src/linux-headers-5.3.0-62-generic’

I got this issue in a Ubuntu 20.04 running a kernel 5.something and also on a Ubuntu 18.04 running a kernel 5.3.0-62-generic.   But the compilation works on an ubuntu 18.04, kernel 4.15.0-112-generic .

Do you have any idea on where this issue might come from ?

Thank you for your help.

Hello,

Make sure your system is configured correctly. Those articles may help you:

Oh, I’m sorry. Actually , that was a little piece that I didn’t do strictly as you mentioned in the links :

I did :

sudo make -f Makefile

and I should have done

sudo su

make -f Makefile

That solved it for the 5.3.0-62-generic ; I will check if it solved the problems on the other OS and keep you informed.

Thanks for your help.
