I have a problem installing sikuli on fedora 16 its a 64 bits architecture, my main problem comes with the compilation of opencv, sikuli requires the 2.1 version of opencv and in the cmake step it tells me it can not find some libraries. I have tried installing the libraries and creating symbolic links but it still will not work, does anybody knows a good tutorial or some good ideas to solve my problem?
I'd recommend you to raise a question on Sikuli bug tracker https://answers.launchpad.net/sikuli because it's quicker to get the response from developers there.

I have been pulling my hair out trying to get mingw and opencv working on Windows for Visual Studio Code for the past three days.
I am using mingw 8.1, and opencv 4.5.2(tried 4.1.1)
The online guides I found apparently don't work, and I even went as far as to build openCV myself to see if it would work, but it did not.
Every version I try throws a procedure entry point could not be located in dynamic link library imgcodecs452.dll error, and I could not find anything online.
Has anyone ran into this issue?
Note that I'm running a very old CPU, pre-AVX x5690, but I did compile for without AVX yet it still failed.
Having an issue with trying to build any opencv version with code::blocks.
I've have built opencv successfully before and have no idea what the issue is.
I've tried following many different tutorials on building opencv using mingw 4.9.2 and CMake. I have also tried using mingw32 and mingw64.
But I continue to receive the errors shown in the image above.
My question is; What is the issue? How can I fix this? And, lastly, what am I doing wrong?
Found that the version of OpenCV I was using had issues with MinGW. Tested a whole bunch of OpenCV versions (3.3, 3.2, 3.1, 2.4.13, 2.4.13.3).
I found that OpenCV version 2.4.9 with the latest version of CMake and MinGW worked.
Thought I'd leave this here to help anyone else having issues with creating OpenCV to work with MinGW/Code::Blocks
I googled this question a lot but couldn't find any solution? Please help.I found help for OpenCV 2.0 and 2.1 but that doesn't work for the latest version 2.4.6. Also I have no idea what CMake and MingW is?
Here is an official installation guide. You should not use dev-c++ because it is old, outdated software. Try some modern IDE like code::blocks or eclipse.
Z3's dependency on libgmp.so.3 is unresolved in the linux package, leaving the user to provide this library. However, this library is very old and is not readily available.
Does anyone know a method for getting around this issue? I am currently running x86_64 and cannot get around this missing dependency without a great deal of hassle.
Is it possible the linux packages could be fixed such they include the expected library in the distribution?
You can get GMP3 by executing sudo apt install libgmp3-dev.
I'm not a Linux expert, but this is the command I used to install GMP before I compiled Z3.
When I installed the virtual machine for running Linux 64, I think I didn't find a package for the more recent versions of GMP.
I will try again. If it doesn't work, I will download the most recent GMP tar ball and build it from scratch.
BTW, the Z3 for Linux 32 comes with two .so files. One of them has GMP statically linked.
The trick I used for building this .so file didn't work for the 64 bit version.
As I said, I'm not a Linux expert, any suggestions on how to build a better Z3 library for Linux x86_64 users are welcome.
sir,
I have tried my level best to install open cv library 2.2.0 version.but it has'nt suceeded
it shows that errors in linking the library hughigh,
whether we wanted to insatll the ipp library prior to install the opencv?
please help me ?..............
I can only recommend the install advice on the OpenCV page. If you are using a unix download the source of the library you want to install and then use cmake to install the library. That usually works fine for me.
Try installing the 1.1 version of OpenCV.
The 2.x version is brand new and as of Nov 1 2009 you will have difficulty finding documentation for that. The 1.1 version of OpenCV, on the other hand, is very well documented and you should have no trouble finding online tutorials for your platform that walk you through the installation process step-by-step.
As an aside: "IPP" refers to Intel's Performance Primitives. In the 1.1 version these are entirely optional. OpenCV does not require them. If you have the Performance Primitives installed, however, your OpenCV code may run faster. (For me it cut down my image processing time by a factor of five.) Once you get everything up and running you can purchase the IPP library from intel here: http://software.intel.com/en-us/intel-ipp/
