Issues with CMake for Opencv
April 7, 2024, 09:03
I have been following this guide https://pimylifeup.com/raspberry-pi-opencv/
when i run Cmake to prepare OPENCV for comp it gives me this "Configuring Incomplete, Errors Occurred!" please help
What does the CMakeError.log say?
a lot like it's a lot of lines
build output check failed
This statement does not help to find the error...
Post the issue on https://pastebin.com/ if it is too long for the chat!
it's pretty big ngl
It looks like you tried it, changed it a bit, tried again, changed it a bit and tried again. Am I right?
actually the first time it installed there was a an error i had to try again for it to finish downloading i then ran the rest of the code
but yeah in short i kinda did that?
You need to know exactly what you did...
Try writing down exactly what you have done so far.
Example:
sudo apt install
sudo apt update
sudo apt install xyz
sudo nano file.txt
I have changed this and that.
So maybe we can find out what happened.
i just used the commands on this guide
i changed nothing
at all
do i just restart from scratch?
A little tip: enter the word
history` to see what command you have used so far.
Here you go
So if you don't have anything important on the Pi, start again from the beginning.
But leave out the Ubuntu repository.
Better just use apt. So either
sudo apt update/upgrade/installor
sudo apt-get update/upgrade/install.And since the libjasper-dev package is optional according to OpenCV, try it without. https://docs.opencv.org/3.4/d7/d9f/tutorial_linux_install.html
want me to format and do a new new install?
i am new to all this so i am a bit confused
Yes
oh god
wait you mean i just need to delete open cv and contrib and restart
or do you mean my pi entirely from start
Reinstall the OS.
ok i will do it
Believe me, it's easier than uninstalling everything... It's usually not as clean as reinstalling the OS.
i can imagine that
ill go get some rest then i haven't slept because of this
28 hours
ill update you when i am back
thank you for your time thunder
This is the worst mistake you can make.
Don't drink, you can hold out for a few days.
Not eating for a few weeks, depending.
Not sleeping clouds your mind. Don't do that. Solutions usually come in your sleep!
That's true
I'll rest a bit
Yo I am back
Reinstalled the os
Ok so i did a different method
i followed this tutorial
no errors but it's a bit confusing given i do not know what to do next for the facial recognition
<@1071178789939331253>
i have followed this tutorial
start to finish
Ping me tomorrow my brain is just not working rn
i have now a virtual env
ah
ok
Sorry
ah i do have a quick question
in thonny
when i try to save
the windo is too damn big
Yes
for me to save
i can't resize it down
you know to actually type and all
😂
I use nano and vim myself
I use lite os so I only see the terminal
No VNC. And it's been a while since I've been on desktop.
May you show me what part is too big?
too vertically big
can't resize it down
used alt
did nothing
i am on VNC so it's not a screen issue
Idk
God it's been a while since I've seen RPi is desktop
i can resize horizontally not vertically
update i am now losing my motivation and will it keeps showing me errors
I did a new fresh os I'll retry
i did a full env install
then i wrote down a code in thonny
i then sent a picture to show
import cv2
img=cv2.imread ("lkma.jpg")
cv2.namedWindow('image',cv2.WINDOW_NORMAL)
cv2.imshow('image',img)
cv2.waitKey(0)
cv2.destroyAllWindows()
it results in this
(env) lkma@raspberrypi:~/project $ python3 test_opencv.py qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in "/home/lkma/project/env/lib/python3.11/site-packages/cv2/qt/plugins"
the image shows up tho
apparently there is some big issues with the Qtwayland plugin?
right now i am installing the facial recognition lib
it's taking a bit long
with dlib being so damn slow
Do you use Bookworm?
If the program has problems with Wayland you should switch to X.11.
sudo raspi-configAdvanced options If this does not work and there is no other solution, the only option is to install Bullseye... By the way, get used to it, in IT everything rarely works immediately and without problems.
i am not sure what to say let me check
A6
Change to X
ill do it once the face recog fails for now i need to write down a few lines of code since i am still trying to "send notif to an app/email" from the pi
For email you need to set up msmtp and specify an SMTP server.
For App I have seen this here https://pimylifeup.com/raspberry-pi-ntfy/, but have not tried it myself. I prefer to use email.
one hiccup is google disable less secure apps ?
kinda confused trying to figure it out
No idea what exactly you mean...
Let me send you a screenshot
Oh this has changed
https://youtu.be/Ee7PDsbfOUI?feature=shared try and follow this
i legit don't know what to do
Yeah me neither actually
I did do this before
No clue where it's gone now
Maybe it's on by default so try continuing on
