How to Use OpenCV 2.48 with CodeBlock on Windows7 , 64 bit [closed]
Need help. I have been using codeblock and openCV using IplImage etc. Developed and used many examples but all IplImage manipulation. Now I want to use mat feature. I am unable to configure CodeBlock with openCV , I have downloaded MinGw ( complete size around 1.3 GB ) , Tried various version of CodeBlock, the best working with me is Version CodeBlock 10.05. with Mingw , but I have not used that : no link , no reference in path / libraries
I have tried to use Cmake to make binaries of MinGW but no success, so deleted all data of CMake and what it produced.
My Path includes ( MinGW is placed in E:\MinGW )
E:\MinGW\bin; E:\MinGW\mingw32\bin; C:\opencv248\opencv\build\x86\vc10\bin ; D:\path ;
I have configures CodeBlock as under:-
Using code::blocks-10.04 for OpenCV 2.4.8 , in Windows 7 64 bit.
Open code::blocks go to Setting->Compiler and debugger, then a popup window opens.
I selected Search directories tab, and below select Compiler tab, gave OpenCV include path,
C:\opencv248\opencv\build\include\opencv2
C:\opencv248\opencv\build\include\opencv
C:\opencv248\opencv\build\include
E:\MinGW\include
Then I Clicked on Linker tab next to Compiler tab added OpenCV bin directory, like
C:\opencv248\opencv\build\x86\vc10\bin , here I used 32 bit binaries. e:\MinGW\bin
Now open Linker settings tab and below Link libraries add OpenCV libraries,
E:\MinGW\lib\libaclui.a etc there are many files Also added all files like this open : E:\MinGW\mingw32\lib\libwin32spl.a
Toolchain is configures for e:\MinGW as shown
I also set the Build Options
then
and
next
I get these errors

C:\opencv248\opencv\build\x86\vc10\bin - that's wrong.
you can't use the visual studio libs with mingw, you will have to build your own opencv libs first.
Or just tell your codeblocks to use the VC compiler. Much easier :)
Hello Berak, I thankyou for your guidance, I removed C:\opencv248\opencv\build\x86\vc10\bin from all settings, still same problem.
Dear StevenPuttemans , can you tell me how to use VC compiler , I have not installed any other IDE like VS etc. This vc came with CodeBlock.
sookhen, you got 2 options now:
Dear Berak , Thanks . I have both downloaded available with me. VS2010 and Mingw almost 1.3 GB data , Got MinGW through mingw-get-setup.exe , have cmake-3.0.0-win32-x86.exe , I also have downloaded MinGWStudioFullSetupPlus-2.exe . I have used codeblocks-10.05mingw-setup.exe to install CodeBlock. I have also tried C::B ver 12 and codeblocks-13.12mingw-setup.exe
Please guide me , which is more stable way, I want to avoid VS2010 as it will restrict the scope. I have tried to build openCV libs, but I could not learn the right way. I did learn, the point is right way ...
Happy reading.
Trying various options, linking libraries , setting path , etc now I am getting this error

Is there a visual compiler 2008? or a visual compiler 2010? If not, just download that one and it will work.
Thanks, I am trying to change the compiler : from Build options , and Toolchain as well. I shall inform you about the results soon. Hopefully, it will be done.
Thanks everybody. I shifted back to VS2010, I wanted to use Open Source IDE like CodeBlock, with experienced programmers guiding and supporting in problem handling. Now I have configured my VS2010 on Win7 , 64 bit , I followed the steps given at this tutorial :- http://answers.opencv.org/question/6495/visual-studio-2012-and-rtlfreeheap-error/?answer=36619#post-id-36619
To pay my gratitude to Berak and Steven Puttemans , I am posting the tutorial I for configuring VS2010 , Win 7 - 32 bit. I did not build libraries for 32 bit, I used those which came with OpenCV2.4.8 in x86 folder .

Thanks a lot.
