xinput issues

[slicer69]

I tried to build the new Lumina snapshot (from Dec 12th) on Debian Linux and ran into a few problems, all with the new xinput code. The problems basically seem to boil down into two things:

1. xinput isn't available in Debian, causing an dependency issue.

2. The xinput website (as it is listed in the FreeBSD port) does not exist, so I cannot learn about xinput and download/build it.

I checked and it looks like other BSDs do not have xinput either, making Lumina more or less tied to FreeBSD-based systems until we can patch around the dependency. Maybe we can add platform checks to the code which basically makes xinput a FreeBSD exclusive feature for now?

xinput isn't available in Debian, causing an dependency issue.
xinput is a standard X component. See: https://www.x.org/releases/current/doc/man/man1/xinput.1.xhtml

I dont know what version of Debian you are running, but this should cover it: https://packages.debian.org/search?keywords=xinput

We have talked internally about different pages for different systems based on what is bundled, but that's something we wont be able to get to immediately.

I might be able to check/disable that page in lumina-config if the utility is not found. Let me look into that....

[beanpole135]

Fixed!

I added a quick runtime check for the "xinput" utility, and if it is not available then the input devices page in lumina-config will not be available.

"I dont know what version of Debian you are running, but this should cover it:"

I should have been more clear. I'm not talking about the xinput executable, but the xinput header file. Lumina fails to build on my system because of a missing compile-time dependency which is not provided by the xinput package. My problem is that the xcb/xinput.h header file is not available. Having a run-time check for the xinput program is a good run-time work around, but first I need to get Lumina to compile.

So far as I can tell, using apt-file, there is no xinput.h header file in Debian.

[beanpole135]

Ok, that makes more sense now.
I think the xcb/xinput.h file is supposed to be included with one of the base XCB library packages. Not sure which one yet - looking now...

[beanpole135]

Yep - part of the base XCB library on FreeBSD:
http://xcb.freedesktop.org

[beanpole135]

It is not even in a separate library bundle. The main "libxcb" dist file looks like it includes it.

[q5sys]

So far as I can tell, using apt-file, there is no xinput.h header file in Debian.
Debian splits header and other dev files into separate packages. I checked and the one that has xinput.h is : https://packages.debian.org/search?keywords=libxi-dev

[q5sys]

Now that I think about this, there are several distros that split dev files into other packages. So this will probably end up being an issue that others face as well.

[slicer69]

Not only that, but the header is in another location. On my system (with libxi-dev installed, thanks for tracking down the package), the XInput.h file is stored in the PREFIX/include/X11/extensions/ directory. Where it looks like Lumina's build process is looking in PREFIX/include/xcb/ for the file. We should probably have this in the search/includ path and mention the libxi-dev package dependency in the documentation.

[beanpole135]

The X11/extensions directory should be for the XLib libraries, not the XCB libraries (same effect - different libraries though)

[q5sys]

Slicer69, can you let me know if other than xinput and libxi-dev that the list that appears in the DEPENDENCY file are correct for Debian?

Did you find that you needed anything else, if so I want to get that added to the list.

[slicer69]

I think those were the only two dependency issues.
I have found that even with those deps in place, I still can't compile Lumina on Debian, but it appears to be a code/Qt issue. I think FreeBSD's ports are far enough ahead of Debian Stable, version wise, that I'm going to need to upgrade more libaries to compile newer versions of the desktop.

[jochenplumeyer]

Same error here on Debian Jessie, "xcb/xinput.h" does not exist in the distro.
From http://stackoverflow.com/questions/10881682/missing-xcb-header-in-debian-squeeze-wheezy
"It seems that XInput Extension is disabled by default because it's not yet stable enough; hence not packaged in Debian."
XCB is compiled without "--enable-xinput "

[slicer69]

That would explain all the xinput/xcb errors I run into when xinput.h has been added to the system. Thanks for confirming it's not just me messing up the build process.

[beanpole135]

Ok - Try this now: dc8e7ac

The new "NO_XINPUT" compile-time flag will disable the use of the xcb/xinput.h class (and disable the input device properties page in lumina-config) if your OS does not have that include file for some reason.

[beanpole135]

New release archive created for 1.2.0 which includes this change:
https://github.com/trueos/lumina/releases/tag/v1.2.0-p1

[slicer69]

I compiled the new Lumina patch and confirmed "qmake CONFIG+=NO_XINPUT LINUX_DISTRO=Debian" works on my Debian Stable system.

Can you also update description of build process on https://lumina-desktop.org/get-lumina/#source-debian page?

[beanpole135]

I just disabled that xinput usage permanently.
The X11 methods for managing input devices are really not that useful - so they should be managed on the OS side of things instead ("moused" on FreeBSD/TrueOS, not sure about other OS's offhand).
