Hi there I'm new to OpenCV. I was trying to make the libraries and it crashed. Any help would be most appreciated.

"can’t write PCH file: No space left on device"

well, i'm on win, but a build here takes ~2gb.

the pch files are quite big, opencv_features2d290.pch alone 16.5mb, so you could trade compile time against disk space and rerun cmake with ENABLE_PRECOMPILED_HEADERS=OFF (but cleanup anything that cmake generated before)

Hi, I have the same Problem, although I got the error on 95% of "make" command. So, I ran cmake without any Problems and then by execution of make I got Problems with space. Can you tell me what should I do to complete the Installation? If the steps are the same as you wrote already, how can I detect, what files were created during "cmake" execution? Should I then run "make" command again? Thanks in advance! Dmitry

you probably told cmake to build into a "build" folder. just delete that whole folder and start again

cmake, make, yes back to start
