Hello, I tried to build my own OpenCV3.1 on windows 7 using MinGW. I configured it to be compatible with Qt and I used my Qt's mingw compiler.

I created a QtBuild directory for this alongside the sources and build directories. After running through all stages, including adding a path to the DLL's created, I get the above error message whenever I want to run one of the examples.

I've looked this up on stackoverflow, and people say that it has something to do with linking with gcc instead of g++, but, heck, I've beed dealing with the building via the CMake configuration, and it doesnt look like I specified one linker instead of another.

Hello, I'm on Windows 7 with Qt 5.3.1 installed. I'm trying to build an OpenCV for use with Qt as suggested by the book Learn OpenCV by Example by Garcia et al. However, despite following the book carefully, it appears that not a single library file is built.

I have created a dedicated build directory QtInstall for a Qt Installation alongside the prebuilt build directory. After having gone through all the steps: configure and generate (and I must say the CMake Gui documentation is dismal). I find that appart from a lot of files that have extension .cmake, a CmakeCache.txt file and a couple of header files, there seems to be a lot of missing files I would expect. For example the subdirectories lib and bin are empy. There is not a single include in the include subdirectory, no doxygen documentation at all, but a doxyfile. There is not a single sample, and so on, just .cmake files everywhere.

However there are some warning signs: In the CMakeCache.txt file there is the following line: GLIB_LIBRARY:FILEPATH=GLIB_LIBRARY-NOTFOUND

I'm guessing that this is related to the Glibc library. How strange, it knows where the MingW gcc compiler is, but not the libraries. The trouble is that there seem to be several candidates for GLIB_LIBARY, and I dont know which one to take.

There is for example C:\Qt\Qt5.3.1\Tools\mingw482_32\lib\gcc\i686-w64-mingw32\lib which contains glibcc_s.sa

There is also C:\Qt\Qt5.3.1\Tools\mingw482_32\lib\gcc\i686-w64-mingw32\4.8.2 which contains a whole lot of files like for example libstdc++.a

So, is GLIB_LIBRARY:FILEPATH part of my problem? If my installation of Qt is so standard, I'm guessing that anyone who has set up Qt 5.3 is going to have the same problem.

Another problem is Python 3 : I have the Anaconda Python Distribution, in C:\Anaconda3 Configure does not find this. Do I have to manually edit all the Python variables? If so how am I supposed to know what the difference between

Python include dir and Python include dir2

?

This is what happens when you do most of your development with another IDE (QtCreator in my case). In QtCreator you have to go out of your way to set different INCLUDEPATH's for Debug and Release environments.

It turned out the inconsistency of the Debug vs Release builds. When I modified one build, the other build was being compiled. VS does this without warning.

That's all very well, but I could post up a screen shot showing my entry for "Additional Include Directories"

for a while I thought I had inverted opencv2 and opencv, but no. Hardwiring the include path is another workaround at first sight, but then using namespace cv causes an error!

Hello, I just uncompressed openCV3.1 and put the source and build directory to this directory:

d:\openCV\openCV3.1\

so

d:\openCV\openCV3.1\build\include\opencv2\opencv.hpp

really exists.

Inside my VS 2015 community edition I created a test project whose first line is

#include <opencv2/opencv.hpp>

My project was a console project which was marked as "empty". In the properties page of the project I have set as additional Include directories the following

D:\openCV\OpenCV3.1\build\include;%(AdditionalIncludeDirectories)

but the error persists: the compiler claims that it cannot open the source file opencv2/opencv.hpp It does not help if I replace the slash by a backslash.

I had exactly the same problem with VS 2013 community edition, and posted a question on stackoverflow, but the people who wanted to help were stuck. At the time I found the workaround of copying the whole lot of include files to my source directory. This is not really elegant.

If I right click on the #include "opencv2/opencv.hpp" I get the following message Any comments?
