Possible Ubuntu 18.10 compatibility issue
Closed this issue · 7 comments
Installed Ubuntu 18.10 yesterday, and while trying to get my Huion Kamvas Pro 13 to work, I tried to install uclogic-tools and ran into this error:

configure: error: Package requirements (libusb-1.0 >= 1.0.0) were not met:
No package 'libusb-1.0' found
However, when checking that I have it installed, I noticed that the naming convention is slightly different:
libusb-1.0-0/cosmic,now 2:1.0.22-2 amd64 [installed,automatic]
There is no other option for libusb when I search across the repositories, so I assume that the one I have installed is what's needed, but perhaps the compiler is failing to find it because of a slightly different label?
Thank you for the report, @Eqlipse. I tried to reproduce the issue on a fresh install of Ubuntu 18.10, but couldn't. Make sure you install the libusb-1.0-0-dev package mentioned in the README.md, though.
Closing now, please reopen if it still doesn't work for you.
Ah. I'd like to clarify something about that readme, then...
Requirements:
libusb >= 1.0
Libusb development packages are usually named libusb-1.0-0-dev or libusbx-devel. Debian-based systems also need the pkg-config package installed.
It doesn't actually say "You need the development version." Reading the statement, it starts off with libusb >=1.0 , which means "greater than or equal to" version 1.0... then says where you can get versions greater than 1.0.
In other words, it's worded incorrectly. If 1.0 is not sufficient, then it should say so, instead of saying that 1.0 is fine, but higher versions will also work (which is what the current wording actually says).
@Eqlipse, please take a look at the updated README.md and see if the instructions are less confusing now.
The original "libusb >= 1.0" condition referred to the upstream package and version, not to distribution package and version, since that's more universal. Also, to build anything you normally need a distribution's development package installed for the upstream package. All of this might be familiar to developers, but certainly not to everyone. So I removed this general description, and only left the more specific instructions to avoid confusion. Hope that's better.

@spbnick It is, thank you for the clarification!
OK, cool 😃
