Hello,
I am developing an interactive C++ application (a game) which is supposed to use the Tobii 4C eye tracker. In order to interface with the eye tracker, I am using the Stream Engine API.
Stream engine api link (download link at the bottom of page): https://developer.tobii.com/consumer-eye-trackers/stream-engine/getting-started/
I added the .h files provided with the API to my project and I added the directory containing the tobii_stream_engine.dll and tobii_stream_engine.lib files to the project library directories.
My issue is that I am getting a LK1107 error (invalid or corrupt file) on thetobii_stream_engine.dll file at the linking stage (not a runtime error). Personally, I think this is a binary compatibility issue as I am using the 2019 MSVC toolset.
Do you have any input?
Thank you,
Hi @davidolivier, sorry to hear about your issues. Could you kindly confirm which Visual Studio version you are using? If not already, we recommend 2019. Have you tried (as a test) both the 32 and 64 bit versions?
If you have a spare system to test that would also be useful as the files themselves have been checked for consistency. I assume that you already tried downloading again , perhaps with a download manager to ensure no lost packets.
Hopefully we will get you up and running soon, thanks for your patience.
Hello again,
I ended up solving the issue by following the steps in the following tutorial (for future reference):
https://docs.microsoft.com/en-us/cpp/build/walkthrough-creating-and-using-a-dynamic-link-library-cpp?view=vs-2019Essentially, I was missing one step : copying the provided .dll next to the executable .exe in my build folder (as recommended in the tutorial). I come from a linux background … I still have to work on my windows devops skills I guess.
Thanks for the quick response!
Cheers
