MinGW Build Error OpenCV 4.8.0

saqib · September 19, 2023, 2:51pm

Trying to build OpenCV 4.8.0 from source on windows with mingw, throws error at around 50%.
I tried both the gcc 13 with mcf threads and gc 12.2.0 with posix threads and seh exceptions but it throws the same error, which is related to videoio.

unfortunately, no mingw version has code for MSMF, so you will have to do without the MSMF & OBSSENSOR backends for videoio

clean prev. build artefacts and add

WITH_MSMF=OFF
WITH_OBSSENSOR=OFF

to your cmake cmdline, rerun cmake && make

Thank You, Very much it really helped, i built without errors, but now there is another runtime error, when i start program it instantly crashes and the fault is in opencv_480world.dll, what my question is that i built with world and i thought it would make a separate world dll alongwith all others but it deleted others, so i would like to use some help building all other modules without going through all that mess again since object files are already present so its just a matter of link. Can you please tell how?

berak · September 20, 2023, 5:55am

code ? error ?
dont make us guess, it’s bad enough if you do …

saqib · September 20, 2023, 6:41am

I would just like to build modules separately because opencv_world is just too large to ship with my little projects that use at max two libraries, so if you can help with that i would be pleased, because my system is slow it already took me freaking 8**hours to build, only to realize it combined all libs into one.

berak · September 20, 2023, 6:44am

indeed, you must check this ! and this:

if (frame.empty())) // ALARM !

most probably, you capture did not open, try index 0 instead

saqib · September 20, 2023, 11:03am

It worked, for some reason Clion shell couldn’t see Environment variables thats why it was crashing, however my question remains same can i build with slight change to config without building it from scratch, i tried modifying Makefile and Cmake files but they are just too many. regenerating obviously starts building from very start.

berak · September 20, 2023, 11:14am

easy:

cmake -DBUILD_opencv_world=OFF

i’m afraid, you’re still making wrong guesses.

if the video capture does not open, it’s because of wrong user supplied params (id, backend) at runtime, it’s not a linking problem

saqib · September 20, 2023, 11:16am

Thanks that really helped… yes I got that crashing part under control now.
