Hello all,,
My objective is to use OpenCV with Eclipse (plugin CDT). Firstly, I downloaded the CDT plugin from help ยป install new software. After that, I added the correct cdt 9.2 url and after downloading the whole 34 files, eclipse had to restart.
After applying all the steps in this link
http://docs.opencv.org/2.4/doc/tutorials/introduction/linux_eclipse/linux_eclipse.html
I got these errors in the screenshot
errors
Best Regards

I am currently working on a Open-Source Project, which has some third-party library dependencies, I have installed all of them using Vcpkg into a particular folder in my E: drive and integrated them with Visual Studio with the "vcpkg integrate install" command, and supplied the Cmake toolchain also in the IDE.
But the libraries (ie. WxWidgets currently) are not being detected while configuring the build.
I am attaching the configuration message as well as the error snapshots below.
Any suggestions regarding this, would of great help.
Thanks & Regards.

I'm trying to write a program that uses SURF algorithm and I know that the nonfree module must be installed separately. I've downloaded and installed the latest version of CMake(3.5.2) and I'm following the instructions from:
https://github.com/itseez/opencv_contrib/ . I'm using the GUI and I run Visual Studio 2015 on a 64 bit Windows 10.
Since I know that for SURF you must include xfeatures2d when it asked me the source of the code I only specified the xfeatures2d folder. When I first pressed the configure button I had some errors(I've attached an image of them). I managed to get rid of one of the errors, the one that said to write a line of code at the top of the file
cmake_minimum_required(VERSION 3.5), but I still have one error:
CMake Error at CMakeLists.txt:4 (ocv_define_module):
Unknown CMake command "ocv_define_module".
I'm also attaching a picture of the CMakeLists.txt. Please help me find the problem.
Also, if you could help my install all modules at once, I would be grateful. Or do I have to set as input every folder in the modules folder?
GUI error and CMakeLists.txt
Try using Visual Studio 12 2013 for compilation, this has worked for me, but not the other (newer) versions of Visual Studio.
I have been trying to build OpenCV 2.4.10 on Windows 7 32bit using Visual Studio 2013 and it has been a real pain. I have make some achivements but unfortunatelly it is not working 100%.
I would like to write a small manual not so focused on the step by step -it can be frustrating when one of those steps fails and you don't know how to reach the next one- and more focused on understanding what is happening on each step, why and what to expect when something goes wrong.
I ask for your help, sure you have faced lot of them before and can explain why it is happening.
I am downloading 3 to build with CMake 3.0.2 and Visual Studio 2013. I will update this thread as I take steps.
My aim is to build 2.4.10 with CUDA, TBB and OpenGL support. And make it work :)
Clone OpenCV 2.4.10 (I am using TortoiseGit at C:\OpenCV\src\src)
Download TBB Compiled
Unzip TBB in C:\OpenCV\src\opt\tbb
Unzip OpenCV source in C:\OpenCV\src dir
Open CMake and target source dir C:\OpenCV\src and built dir C:\OpenCV\built
Configure CMake for the first time
Select Visual Studio 12 2013, Use default native compilers for a configuration Win32
Select this options:
Under WITH tab:
WITH_CUDA (already checked)
WITH_OPENGL
WITH_TBB
And click configure again...
Here, OPENGL libs are found (opengl32 and glu32) and first missing paths appear (TBB_INCLUDE_DIRS), those for TBB_INCLUDE_DIRS, so:
Point that line to C:\OpenCV\src\opt\tbb\include and click configure again.
After that configuration process, TBB tab appears in red with LIB_DIR and STDDEF_PATH labels pointed to my TBB folder.
Click configure again to confirm the changes.
This time, there are no tag in red, and everything seems to be fine. I check the output and GUI OpenGL support is set to Yes, and so is Use TBB (ver 4.3 interface 8002) under Other third-party libraries, so
Click Generate to generate the Visual Studio files
Files are generated, so
Open Visual Studio 2013 and open OpenCV solution at C:\OpenCV\built and wait for it to be ready
Select Debug and then Build Solution (Ctrl+Shift+B) and wait...
First errors happen when it tries to find the core lib, so I re-run CMake for a simple build, without OpenGL, CUDA or TBB.
I have found this guide:
Which point to several of the problems I have been having. After compiling with its recommendations now I am having a particular problem regarding throw_nogpu that I will look for.
This guide solved my problems with CUDA, OpenGL and TBB:

I hope it helps.
I was successful in installing MINGW32 and CMake and rebuilt OpenCV 2.3.2 (the superpak). But V2.4.2 is not the superpak and doesn't have all the files that V2.3.1 has. My attempt to rebuild was very short (seconds rather than 20 minutes). This is Win XP Pro SP3.
The OpenCV wiki and various guides don't work because the V2.4.2 package is very different. The Yahoo OpenCV group does not respond. My guess is they don't know.
Can I/Do I rebuild V2.4.2, and if so how?
Same way you build any other version.
Run cmake-gui, configure, generate then build the resulting .sln

I am following the Slashdev Blackberry development tutorial to setup BB development environment.
I am done with the first part of the tutorial, when i follow the second part.
then I get the following error on building the HelloWorldApp via Ant:
BUILD FAILED
C:\Documents and Settings\acernet135\workspace\HelloWorld\res\build.xml:16: jde home must be a directory
Total time: 172 milliseconds
Any help? How to sort this out? Thanks
Those instructions are pretty old. You should look at the latest JDE Plug-in instructions and also look at my Windows 7 notes about this process.
