We got a problem in make -j4 can it fix ? c++: error: unrecognized command-line option ‘--param=ipcp-unit-growth=100000’; did you mean ‘--param=ipa-cp-unit-growth=’?
Have you fixed the problem yet. In my case, I am getting same error message and then at 22% I am getting an error message. Pi is getting hanged when we are using make command. I am using RaspberryPi 3B+ and trying to build openCV 4.0.0.
I tried exactly the way in Raspberry PI, all seemed to be worked, but at the end the "import cv2" says there is no cv2 module, I tried to run at least c code, it couldn't find any opencv libraries. Where the libraries are located?
hi there I followed your steps carefully and i have one issue on step 9(Instructions for Compiling), after i wrote all the lines an error message appears saying that "bash: cmake: command not found". how can I resolve this?
You don't have make and cmake installed in your raspberry pi3. Run following command to install them in the raspberry pi3. sudo apt-get install build-essential cmake it will take some time approx 2 minutes. so just hold tight and let it be finished. after that you surely wont get this error.
Awesome work, just a heads up for anyone running into this error copy-n-pasting the "make -j4" code straight off the blog: "make: *** No rule to make target '-j4'. Stop." my experience is that the dash ( - ) at the side of the 'j' changes when pasting into the terminal. The '-j' is suppose to be read as an option and the '4' it's argument. That's what I get from copying and pasting too much

what if you want to work with python3 (3.7)? you just tested python 2.7.16..
