getting error when run mingw32-make: cap_dshow.cpp file error
HI, After setting necessary things, When I run mingw32-make in command line, up to 41% Many things were gone fine with few warnings. But at 42%, it stopped due to error in module/videoio/cmakefiles/opencv_videoio.dir/src/cap_dshow.cpp.obj failed
After searching this website, someone recommended to check for broken Cap_dshow.cpp (missing "/" on comment, etc). when I go through the Cap_dshow.cpp file, i think something missing in the file but I could not able to recognize the error. Can anyone give me working cap_dshow.cpp file to replace the error file? Or could be there any other issue?
my OS: MS Windows 7 32 bit Opencv: opencv-4.0.0-vc14_vc15.exe
advance thanks

your pictures are useless here.
please replace the screenshots with a TEXT version, so we can quote you properly, it can be indexed for search, etc. thank you !
(also, they don't show any real error, which must be some lines higher up, so please look again !)
also: which mingw are you trying with, exactly ?
mingw version: i686-5.1.0-release-posix-dwarf-rt_v4-rev0 (extracted to folder C:\mingw)
Tried "mingw-w64-install" using "mingw-get-setup" msi (Folder C:\Program Files..\mingw)
OS: MS Windows 7 32 bit , IDE: Netbeans 8.0.2 , Make: msys ("MSYS-1.0.11") , CMake: CMake("cmake-3.13.1-win32-x86") ,
Warnings Received: 1. D:\opencv\sources\modules\core\src\lda.cpp:187:39: warning: unknown conversion type character 'z' in format [-WFormat=] ,
..... same type of warnings in many .cpp files
Error Received (at final, Stopped): mingw32-make[2]: [modules\videoio\CMakeFiles\opencv_videoio.dir\build.make:61: modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_dshow.cpp.obj] Error 1 mingw32-make[1]: [CMakeFiles\Makefile2:4127: modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2
makefile:161:recipe for target 'all' failed ,
mingw32-make: [all] Error 2
those are still only warnings. and mingw 5.1.0 is VERY old (and might not work here)
please have another look at the compiler output. if you cannot find it, edit your question, and put the make output there. (NOT into comments !)
latest mingw downloded and installed and run.
g++ version = 8.1 ,
gcc version = 8.1 , msys make version = 3.81 ,
CMake version = 3.13 ,

Netbeans IDE 8.0.2 ,
OS : Windows 7 32 bit ,
same result. Any help? thanks
since you seem unable to find the error, please add the make output TO YOUR QUESTION
Sorry to ask you this. Where is the output of the 'make' file resides?
on a console, in some window, idk. how you run make.
but the cmake output is already valuable ! please change your cmake flags like this:
and rerun cmake configure / generate
tried. but not succeeded yet. when I run cmake cmd (after configure, Generate), it is not reaching up to 100%. it stopped at 42% as earlier. The same file cap_dshow.cpp. cmd takes 2 to 3 hrs to reach 42%.
when I run netbeans using simple "Hello World !", it displays the "Hello World !" text and also error as read from master failed : Input/output error Hello World !
RUN FAILED (exit value 1, total time: 4s) When i include #include <opencv2 opencv.hpp=""> and run,
it displays error as
main.cpp:9:10: fatal error: opencv2/opencv.hpp: No such file or directory
#include <opencv2 opencv.hpp="">
^~~~~~~~~~~~~~~~~~~~ Any other issu
again, we canonly help you, if we see the real error msg. and no, that is not the final one.
how to capture entire output of cmd window to show you complete compiling result?
you can either mark it with the mouse directly, or right-click on the title bar -> edit -> copy
For your info: I have followed the sequence mentioned in this blog:
http://cerkala.blogspot.com/2015/09/o...
that's from 2015 :\
and mentioning other ppls blogs is kinda useless here. we need to see, what you did, not someone else.
I have added the all warnings and errors on original post using editing. Kindly excuse for the huge code. Could not able to attach notepad. if there is any other option, pl let me know. Just copy the entire code (added lastly) to notepad and view in full view. Then only you can identify the errors easily (thru' error pointer).
FYI: The errors are mostly inside the sprintf, snprintf and format. When I run the configure CMake, there were some errors received on INT8, INT16, INT32 in CXX
waiting for your reply. advance thanks
Any help ?
I have removed all the warnings and posted only errors. I believe that there is a problem only in sprintf(), snprintf() function. Pl see the error code and try to provide help. thanks.
