Hi guysI have a problem when I need to configure the ide Dev c ++.I can not know why this error happens and the tutorials I find on the internet talk about openCv 2.X and the truth is that what they speak does not work for me.I need you to please help me.
- Sep 20, 2014 首先,先下載Dev-C和OpenCV: Dev-C OpenCV 先建立一個專案,然後設定相關編譯參數。 從Tools - Compiler Options中設定,分別要設定4個地方: 加入需要連結的lib檔,如果是debug模.
- Could you please send a good one for setting DEV C for OpenCV? Thanks, Update 2: Hi berak, I'm still having the linker problem in DEV C, when I compile the code it can't find the header file. I think I have included the right folders. Do you have any idea or could you please send the best way to set up the linker stuff in DEV C for.
Jun 04, 2008 請問一下 你在這一篇文章所示範的OPENCV版本是否為1.0阿 因為我安裝的是1.1 所以在按照你所寫的要include時並無C:Program FilesOpenCVotherlibscvcaminclude這一個選項 而且在otherlibs只有highgui,ffopencv以及graphics這三各資料夾 這是不是因為版本不同的關係所造成的 若是的.
The text of the error is the follow:
- main.cpp:(.text$_ZN2cv3MatD1Ev[_ZN2cv3MatD1Ev]+0x36): undefined reference to `cv::fastFree(void*)'
- 'main.cpp:(.text$_ZN2cv3MataSERKS0_[_ZN2cv3MataSERKS0_]+0x114): undefined reference to `cv::Mat::copySize(cv::Mat const&)' '
- 'main.cpp:(.text$_ZN2cv3Mat7releaseEv[_ZN2cv3Mat7releaseEv]+0x48): undefined reference to `cv::Mat::deallocate()' '
i downloaded the follow example:
Thanks for your help.Sorry my English is not very good :(

which compiler is used there ? (if that is mingw, then you have to BUILD the opencv libs from src first)
(and please check
gcc -v
, and report back, it might be too old to be usable anyway)ok. the ide: Dev c++ version 5.11.compiler: MinGW64How can I do that?
how can I do that. And I change the compiler settings and set the binaries directories but nothing. Also the opencv folder does not have a pckg file ..Some tell me that the dev c ++ has not been supported for a while, but I was able to use the SDL library without problems.What 'ide' do you recommend me then?Thank you
your IDE is entirely irrelevant. Classic vst plugins download. your compiler is (at least here).
and yes, devcpp5.1.1 is from 2012, that's far too long ago for a fast moving thing like opencv
and no, you can't use any prebuild libs, they are for visualstudio2015/17 only. either get that (recommended, huge download, though) or latest mingw64 (like 7.2 or 7.3 you would still have to build libs from src, though).
I think it's time to leave behind the old dev c ++. I'm going to use the visual studio. I do not see another solution. There seems to be no way to couple the devc ++ and the open cv 3.4.X. Thanks for answering
ok sorry one thing more:I can use codeblocks?really i dont like visual stuido
idk abourt codeblockks, but again, the compiler matters here, not your fav. IDE
The following steps have been tested for Ubuntu 10.04 but should work with other distros as well.
Required Packages
- GCC 4.4.x or later
- CMake 2.8.7 or higher
- Git
- GTK+2.x or higher, including headers (libgtk2.0-dev)
- pkg-config
- Python 2.6 or later and Numpy 1.5 or later with developer packages (python-dev, python-numpy)
- ffmpeg or libav development packages: libavcodec-dev, libavformat-dev, libswscale-dev
- [optional] libtbb2 libtbb-dev
- [optional] libdc1394 2.x
- [optional] libjpeg-dev, libpng-dev, libtiff-dev, libjasper-dev, libdc1394-22-dev
- [optional] CUDA Toolkit 6.5 or higher
The packages can be installed using a terminal and the following commands or by using Synaptic Manager:
[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
Getting OpenCV Source Code
You can use the latest stable OpenCV version or you can grab the latest snapshot from our Git repository.
Getting the Latest Stable OpenCV Version
- Go to our downloads page.
- Download the source archive and unpack it.
Opencv C++ Documentation
Getting the Cutting-edge OpenCV from the Git Repository
Launch Git client and clone OpenCV repository. If you need modules from OpenCV contrib repository then clone it as well.

For example
![Include Include](/uploads/1/3/3/9/133935032/101908996.jpg)
git clone https://github.com/opencv/opencv.git
git clone https://github.com/opencv/opencv_contrib.git
Building OpenCV from Source Using CMake
How To Include Opencv In Dev C Mac
- Create a temporary directory, which we denote as <cmake_build_dir>, where you want to put the generated Makefiles, project files as well the object files and output binaries and enter there.For examplemkdir build
- Configuring. Run cmake [<some optional parameters>] <path to the OpenCV source directory>For examplecmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .or cmake-gui
- set full path to OpenCV source code, e.g. /home/user/opencv
- set full path to <cmake_build_dir>, e.g. /home/user/opencv/build
- set optional parameters
- run: “Configure”
- run: “Generate”
- Note
- Use
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local .
, without spaces after -D if the above example doesn't work.
- Description of some parameters
- build type:
CMAKE_BUILD_TYPE=ReleaseDebug
- to build with modules from opencv_contrib set OPENCV_EXTRA_MODULES_PATH to <path to opencv_contrib/modules/>
- set BUILD_DOCS for building documents
- set BUILD_EXAMPLES to build all examples
- build type:
- [optional] Building python. Set the following python parameters:
- PYTHON2(3)_EXECUTABLE = <path to python>
- PYTHON_INCLUDE_DIR = /usr/include/python<version>
- PYTHON_INCLUDE_DIR2 = /usr/include/x86_64-linux-gnu/python<version>
- PYTHON_LIBRARY = /usr/lib/x86_64-linux-gnu/libpython<version>.so
- PYTHON2(3)_NUMPY_INCLUDE_DIRS = /usr/lib/python<version>/dist-packages/numpy/core/include/
- [optional] Building java.
- Unset parameter: BUILD_SHARED_LIBS
- It is useful also to unset BUILD_EXAMPLES, BUILD_TESTS, BUILD_PERF_TESTS - as they all will be statically linked with OpenCV and can take a lot of memory.
- Build. From build directory execute make, it is recommended to do this in several threadsFor example Black guy beat boxing auto tune.
- [optional] Building documents. Enter <cmake_build_dir/doc/> and run make with target 'doxygen'For examplemake -j7 doxygen
- To install libraries, execute the following command from build directory
- [optional] Running tests
- Get the required test data from OpenCV extra repository.
For examplegit clone https://github.com/opencv/opencv_extra.git- set OPENCV_TEST_DATA_PATH environment variable to <path to opencv_extra/testdata>.
- execute tests from build directory.

- Note
- If the size of the created library is a critical issue (like in case of an Android build) you can use the install/strip command to get the smallest size possible. The stripped version appears to be twice as small. However, we do not recommend using this unless those extra megabytes do really matter.
