LNK1107: invalid or corrupt file: cannot read at ERROR

[Chris Kawa]

Change all the LIBS lines from these:
@
LIBS += C:\Users\hamit\Desktop\opencv\release\bin\libopencv_core2410.dll
...
@
to these:
@
LIBS += -LC:/Users/hamit/Desktop/opencv/release/lib -lopencv_core2410
...
@
Notice "lib" instead of "bin", the -L without space before the path and -l(lowercase L) before the library name and no "lib" prefix or extension. Also \ is an escape character so either use / (recommended) or \.
After that place the .dll files in the directory where your app executable is and also don't forget to run Build->run qmake.

INCLUDEPATH += C:\Users\hamit\Desktop\opencv\release\install\include

LIBS += -LC:\Users\hamit\Desktop\opencv\release\lib -lopencv_core2410
LIBS += -LC:\Users\hamit\Desktop\opencv\release\lib -lopencv_contrib2410
LIBS += -LC:\Users\hamit\Desktop\opencv\release\lib -lopencv_highgui2410
LIBS += -LC:\Users\hamit\Desktop\opencv\release\lib -lopencv_imgproc2410
LIBS += -LC:\Users\hamit\Desktop\opencv\release\lib -lopencv_calib3d2410

i did like that but it gave me error again.. just error name changed.. its LNK1181: cannot open input file'..... '

[Chris Kawa]

The '...' is very important :) It tells you which file is problematic. Did you verify that it exist at that location?

[hamit1453]

its 'opencv_core2410.lib'

and i just added .dll files..not .lib's

Which compiler are you using ? Which compiler was used to build OpenCV ?

[hamit1453]

i did my project with visual studio 2010. i want to make ainterface with Qt 5.1

[SGaist]

Was OpenCV also built with VS2010 ?

[hamit1453]

Hello!
In order to overcome this pb you should just edit the compiler. According to the video you should choose Mingw Release.

Go to projects ( parameter compilation) and modify it!
Good luck!
