Gamecon Module not found

Milesc22

I am trying to install the gamcon gpio rpi module, but when I try via the retropie setup it says it failed. Module gamecon-gpio-grpi not found. I have tried several things I found on other forums and I have not been able to find anything that works for me.

@BuZz I have tried updating everything and installing. No luck. Then I did rpi-update which updates to 4.4.15 which there isn't a header on niksula.hut, so I guess at this point I have to downgrade my kernel. Nothing I tried before worked and to be honest I got it to work once before but I have no idea why. I returned to my pi after a few days and what had previously failed to install suddenly work. To my knowledge I did nothing different and now I'm experiencing the same issue. When it tries the first time it says something like bad version number - and then after that it will say failed on every attempt cause module not found

rpi-update will break it as there are not prepackaged kernel headers for that version (rpi-update should be avoided unless you need to specifically test something)

you need to be on the latest retropie-setup and the latest packaged kernel (which has a matching headers package)

you could try sudo apt-get update; sudo apt-get install --reinstall raspberrypi-bootloader raspberrypi-kernel raspberrypi-kernel-headers

I need to see logs of errors to be able to advise further.

@BuZz So I'm not familiar with how to view logs. If so I could potentially look into this further myself. Where are logs located for these types of errors?

~/RetroPie-Setup/logs (gzipped - unpack with 7-zip or so)

@BuZz Thank you! I currently reformatting an SD card to start fresh. Hopefully I will have better luck this time.
