Could not successfully build powerblock - PowerBlock Driver (opt/retropie.../build/powerblock not found)

The error

[ 88%] Linking CXX executable powerblock
/usr/lib/gcc/arm-linux-gnueabihf/6/../../../libwiringPi.so: undefined reference to `fcntl@GLIBC_2.28'
collect2: error: ld returned 1 exit status

indicates you have a wiringpi library compiled agains another system (Raspbian Buster ?). Did you install it manually or you modified your apt sources to include something else than the Raspbian Stretch repositories ?

I've run the compilation on a RetroPie 4.4.x system and I didn't get the error you have during compilation of controlblock.

I installed wiringpi from here:

http://wiringpi.com/download-and-install/

I installed it this way:

To update or install on a Raspbian-Lite system:

sudo apt-get install wiringpi

@mikealves wiringpi is already installed on a RetroPie system, however installing it through apt-get is also ok - but you didn't answer my other question: did you add extra-repositories to your apt sources ?

Hey. I just followed the instructions on the WiringPi site and wound up with this.

100%] Installing service.
[....] Starting powerblock (via systemctl): powerblock.service.
[100%] Built target installservice
/home/pi/PowerBlock
[SUCCESS] The PowerBlock driver binary is installed
[SUCCESS] The PowerBlock service is running
You can find the configuration file at /etc/powerblockconfig.cfg.

Now it works fine. Thank you for your help. This noob wouldn't have figured without your help. Thanks so much for everything!

Glad to hear that!
Just in case, I have just updated the ControlBlock and PowerBlock modules such that wiringpi gets installed as APT packages as part go the module installation process.

I had to reinstall RetroPie (long story). Now I am getting this error when I try to reinstall PowerBlockService.

Does it work if you run the quick installation command from https://github.com/petrockblog/PowerBlock#quick-installation?

That one does not work for me, build stops with

Had to install wiringpi manually, and to execute steps from https://github.com/petrockblog/PowerBlock manually. Seems to be a version mismatch with library wiringpi.

@superpie3k Thanks for your responses. I was away on vacation and only just got back to this. I had the same experience as above. "Had to install wiringpi manually, and to execute steps from https://github.com/petrockblog/PowerBlock manually. Seems to be a version mismatch with library wiringpi." But I got it working now.

For future note: I removed the dependency to WiringPi now. Please see also https://retropie.org.uk/forum/topic/23328/powerblock-driver-quick-installation-fails/5.
