[Solved] UE4.9 EyeXSamples Build Fail

[Stuart Butler]

Hi Folks,

Just tried to build the project and get a lengthy compile error, I’ve added the include to the EyeXPlayerController.h as mentioned by others on here however I still get the following compile errors.

Any ideas?

Cheers

Stu

Got the project to build using 4.8 so I’m assuming 4.9 is the issue.

I’m not a C++ programmer so I’m not sure where to start with this.

Hi Stu,

I’m working on getting a functioning EyeX for UE4 plugin up and running, but it might take some time. The main API change for UE4.9 is solved by this pull request: https://github.com/Temaran/EyeXforUE4/tree/v/4.9. When I tested that branch with the EyeX demo scenes it seems some Blueprint code is broken, so I cannot merge that pull request as is. You might want to try using that branch in the meantime if you need to be on UE4.9.

[Jenny [Tobii]]

Hi Stu,

I have fixed the EyeX for UE4 plugin and there is now a v/4.9 branch that should be working out-of-the-box.

[Stuart Butler]

Awesome!!

I’ll take a look ASAP.

Thanks!!

I tried both v 4.x and v 4.9 samples for both 4.8.3 and 4.9.2 but both are giving me the same error.

[Kishor]

Ok, the solution is
Don’t follow the instructions in readme file that comes with project zip, they are not updated. Follow the updated instructions from here.

[Jenny [Tobii]]

Hi Kishor (@kishorpd),

I don’t understand what readme was incorrect?
The one shown here: https://github.com/TobiiTechnology/EyeXforUE4/tree/master, is the same as the one you are pointing to, and the one included in the project zip if you download from GitHub.

[Kishor]

Oops, sorry!

Actually this error occurs, if we miss this step:

– Extract the EyeX SDK files and copy the lib and include directories to the
Plugins/TobiiEyeX/ThirdParty/EyeX folder of the EyeZ plugin. (Note that
the SDK license differs from the one used for this plugin.)

I missed that step because I thought we’ve to just extract the stuff and did not read that we have to copy the files. My bad.
(And went un-noticed as even my friend had missed the same step.)

Yep, the steps are completely fine no matter from where you follow, because the files are same. Again sorry!:(

And yep, the device is amazing! Excited to start developing!:)
