Nxusb does not compile on Rocky 9.4

Hi guys,

It seems the latest version of nomachine(8.14.2) does not compile the nxusb driver. Default dependencies installed, gcc, make, but seems more like a compiler compatibility issue?

make: Entering directory ‘/usr/src/kernels/5.14.0-427.40.1.el9_4.x86_64’ CC [M] /var/lib/dkms/nxusb/1.0.0/build/nxusb-vhci-hcd.o CC [M] /var/lib/dkms/nxusb/1.0.0/build/nxusb-vhci-iocifc.o /var/lib/dkms/nxusb/1.0.0/build/nxusb-vhci-hcd.c: In function ‘vhci_hub_control’: /var/lib/dkms/nxusb/1.0.0/build/nxusb-vhci-hcd.c:713:28: warning: this statement may fall through [-Wimplicit-fallthrough=] 713 | if (hcd->speed != HCD_USB3) { | ^ /var/lib/dkms/nxusb/1.0.0/build/nxusb-vhci-hcd.c:718:17: note: here 718 | case USB_PORT_FEAT_RESET: | ^~~~ /var/lib/dkms/nxusb/1.0.0/build/nxusb-vhci-iocifc.c:1198:10: error: ‘struct class’ has no member named ‘owner’ 1198 | .owner = THIS_MODULE, | ^~~~~ In file included from ./include/linux/linkage.h:7, from ./include/linux/kernel.h:8, from ./include/linux/list.h:9, from ./include/linux/module.h:12, from /var/lib/dkms/nxusb/1.0.0/build/nxusb-vhci-iocifc.c:41: ./include/linux/export.h:17:21: error: initialization of ‘const char *’ from incompatible pointer type ‘struct module *’ [-Werror=incompatible-pointer-types] 17 | #define THIS_MODULE (&__this_module) | ^ /var/lib/dkms/nxusb/1.0.0/build/nxusb-vhci-iocifc.c:1198:18: note: in expansion of macro ‘THIS_MODULE’ 1198 | .owner = THIS_MODULE, | ^~~~~~~~~~~ ./include/linux/export.h:17:21: note: (near initialization for ‘vhci_iocifc_class.name’) 17 | #define THIS_MODULE (&__this_module) | ^ /var/lib/dkms/nxusb/1.0.0/build/nxusb-vhci-iocifc.c:1198:18: note: in expansion of macro ‘THIS_MODULE’ 1198 | .owner = THIS_MODULE, | ^~~~~~~~~~~ cc1: some warnings being treated as errors make[1]: *** [scripts/Makefile.build:299: /var/lib/dkms/nxusb/1.0.0/build/nxusb-vhci-iocifc.o] Error 1 make[1]: *** Waiting for unfinished jobs…. make: *** [Makefile:1936: /var/lib/dkms/nxusb/1.0.0/build] Error 2 make: Leaving directory ‘/usr/src/kernels/5.14.0-427.40.1.el9_4.x86_64’

Thanks!

Hi, thanks for reporting, we are checking and will let you know our findings soon.

Thanks for looking into that!

Quick question, in the README file in the nxusb source dir I see a mention of usb-vhdi. I did manage to compile and install the 1.15.6 version of usb-vhdi using dkms and loaded it. Is that sufficient for nomachine or nxusb is a customised vhdi kmod? (can’t see any usb devices ready for connecting to the remote host with usb-vhdi)

I also can’t see a mention in the rpm install script of the nomachine rpm package attempting to compile/install nxusb, not sure if maybe that’s removed for some reason.

To compile nxusb kernel module you have to delete line 1198: ".owner = THIS_MODULE," in "/usr/NX/share/src/nxusb/nxusb-vhci-iocifc.c" and then run sudo make in the same directory as that file.
