Hi plop38746,
“When I follow the article instruction to build the module I get the error posted below.”
please do not use ‘sudo make’ because sudo drops the PWD environment variable and causes compilation problems. We have just updated https://www.nomachine.com/AR12J00658 to state it more clearly.
Additionally we found that there is a compilation error (the fix will be shipped with the new packages that we will release soon).
You can fix the problem manually:
IMPORTANT: Let’s assume that NoMachine is installed in /usr/NX.
1. Navigate to /usr/NX/share/src/nxusb
2. Edit ‘vhub.h’ file in your favourite text editor.
If you’re using vi or vim you can skip directly to the line in question:
$ vim vhub.h +60
3. Edit the 60th line that currently is:
enum { VHUB_NUM_PORTS = USB_MAXCHILDREN > 15 ? 15 : USB_MAXCHILDREN };
to have:
enum { VHUB_NUM_PORTS = 15 };
4. Save the changes in file (:wq in vim).
5. You are now ready to compile the module.
6. Be sure that you run ‘make’ as non-privileged user:
$ make
If the build fails due to permission problems, run the following command:
$ sudo rm -rf /usr/NX/share/src/nxusb/include/linux
And then retry:
$ make
If there are still problems with permissions, run the compilation as root. Use ‘su’ and then run the ‘make’ command.
