Hello All,

Below is the error which i am facing when i build with an command mingw32-make:

Thanks for the response. How to attach the file in the forum? Anyways i am copying the last few line of errors manually. Below is the error list,

mingw32-make[2]: * [modules\videoio\CMakeFiles\opencv_videoio.dir\build.make:263: modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_msmf.cpp.obj] Error 1 mingw32-make[1]: [CMakeFiles\Makefile2:4159: modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2 mingw32-make: ** [Makefile:162: all] Error 2

what you show is not the actual error, which must be a few lines up in the output. can you look again ?

and which gcc --version is used ?

(also please put code / errors into your QUESTION as requested, not into comments)

How to attach the file in the forum?

just paste the text there.

please use those cmake flags for mingw:

ENABLE_PRECOMPILED_HEADERS=OFF
WITH_MSMF=OFF
CPU_DISPATCH=""

I have pasted the error in the QUESTION now. gcc version i am using is 7.2.0

i have set PRECOMPILE HEADERS to off in CMAKE gui.

it is still trying to compile the MSMF video backend, and fails there (mingw is lacking some headers for it), so you have to disable thatfrom cmake:

WITH_MSMF=OFF
CPU_DISPATCH=""

then it should build fine. (i'm using ming64 7.2.0, too)

Yeah thanks for your help. Its working now! I am able to use the OPENCV4.0 successfully. But, by turning off the MSMF will this have limited functionality and whats the functionality usage of MSMF.

it's an alternative webcam backend (to the venerable, but still working directshow one)

So MSMF is related to webcam functionality, Since i have turned off this now will this impact in future if i plan to use some webcam application.
