im at step to install opencv

cmake -D CMAKE_BUILD_TYPE=RELEASE \
                                -D CMAKE_INSTALL_PREFIX=/usr/local \
                                -D INSTALL_PYTHON_EXAMPLES=ON \
                                -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-4.4.0/modules \
                                -D BUILD_EXAMPLES=ON ..
make -j $(nproc)

but when it installing like 20-30 min it’ll auto restart my raspberry pi and i can’t do the next step

**sudo make install && sudo ldconfig**
**sudo reboot**

in the end how to fix it
I’m using raspberry pi B model 4 8GB

Make: *** [Makefile:166: all ] Error 2

Your Raspberry Pi should have adequate cooling. Use a heatsink and a fan if possible to prevent overheating.

Hi Phitak,

Welcome to the forum! What Pi OS are you using? This guide of ours was made for Buster, if you are using Bookworm it may be a bit trickier.
