RPi 3b+ Ubuntu 20.04.1 LTS (arm64) compile error #4

Closed h45h3ncryp73d closed 2 years ago

h45h3ncryp73d commented 3 years ago

I was trying to compile raspi-fanshim on my RPi and I can"t get past sudo cmake .. CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: wiringPi_LIB linked by target "RaspiFanshim" in directory /home/ubuntu/raspi-fanshim linked by target "RaspiAPA102" in directory /home/ubuntu/raspi-fanshim/dependencies/raspi-apa102

wiringpi is installed ...

Any ideas how to solve this? Thanks.

It seems like you did not install the wiringPi library.

sudo apt install wiringpi

Not sure if the lib is available in the default Ubuntu repositories tho.

$ sudo apt install wiringpi Reading package lists... Done Building dependency tree Reading state information... Done wiringpi is already the newest version (2.50-0ubuntu1). 0 upgraded, 0 newly installed, 0 to remove and 5 not upgraded.

No it is already installed ...

Strange. Cmake does not seem to be able to detect wiringPi on your machine using the find_library() function.

Can you tell me at what location the library got installed?

$ sudo dpkg -L wiringpi /. /usr /usr/bin /usr/bin/gpio /usr/share /usr/share/doc /usr/share/doc/wiringpi /usr/share/doc/wiringpi/People /usr/share/doc/wiringpi/README.TXT /usr/share/doc/wiringpi/copyright /usr/share/man /usr/share/man/man1 /usr/share/man/man1/gpio.1.gz /usr/share/doc/wiringpi/changelog.Debian.gz

Can you try copying it to /usr/lib and test again?

Or try out cmake -DCMAKE_LIBRARY_PATH=/mypath to make Cmake search at the correct location.

Hmm ... can you please be more precise ... Copy /usr/lib/aarch64-linux-gnu/libwiringPi.so.2 or /usr/bin/gpio?

Or try out cmake -DCMAKE_LIBRARY_PATH=/mypath to make Cmake search at the correct location.

Tried sudo cmake -DCMAKE_LIBRARY_PATH=/usr/bin and got ~/raspi-fanshim$ sudo cmake -DCMAKE_LIBRARY_PATH=/usr/bin CMake Warning: No source or binary directory provided. Both will be assumed to be the same as the current working directory, but note that this warning will become a fatal error in future CMake releases.

Tried all of sudo cmake -DCMAKE_LIBRARY_PATH= /. /usr /usr/bin /usr/bin/gpio /usr/share

and got the same error. Even tried re-installing wiringpi ...

Funny ...

Sadly I don't have a Pi up and running right now so I can't even check on the default Raspbian installation. Never worked with Ubuntu on these devices as well ...

Trying out the different pathes was just a wild guess. Found out there seems to be a debug command-line option. Please invoke cmake using cmake -DCMAKE_FIND_DEBUG_MODE=true and paste me the debug output.

Thanks for trying anyway .. Ubuntu wasn't my first choice but the only one supporting arm64 at the time ... I see Debian is getting there too ... And Raspian hmm ... slowly? getting there ...
