Best free IDE for OpenCV on Linux Mint for GUI development? I'm using Mint 18.1 with Cinnamon as a desktop. I would like

Re: Win 7 with OpenCV 2.4.10, CMake, MinGW32, and Code::Blocks.

I have rebuilt both static and shared (dynamic) libraries for Windows, and written some simple applications in C::B. However, no application works unless the dynamic libraries PATH is set indicating that linking to static libraries alone does not produce a stand-alone executable. Has anyone managed to build a stand-alone program (one that does not need the presence of dynamic libraries), and if so, how?

Rebuild instructions that I have from the web indicate the use of the terminal commands "MINGW32-make" and "MINGW32-make install". I would have expected to use "cmake-make" and "cmake-make install" instead, but cmake-make does not exist. Is CMake strictly for creating make files? Can it not be used execute the make scripts it generates? Am I missing something here?

This for Win 7 64 bit and Eclipse CDT and not the MSVS tools. I have installed CMake, MINGW32 and OpenCV 2.4.10 I have run CMake-gui and understand it. I am now experimenting with re-building OpenCV.

After being mired down in details of re-building OpenCV for Windows 7, my head is still "in the weeds", so I need to ask what are likely dumb questions to regain my bearings:

I have rebuilt OpenCV with MinGW32. But what exactly have I built: Win32 libraries?

If I now install the QT development environment, does it come with MinGW32 and do I need to re-build OpenCV with that development tool? If so, again, what am I building; something different from what I build before I installed QT?

What is the best development platform and tools to create standalone CV applications (that don't need an IDE to run in)?

It seems that changes to the Install Guide wiki pages is not possible; I cannot create an account. I have documented a method for installing OpenCV V2.4.2 for use with Code:Blocks. The existing information is misleading and so I would like to correct it. How can I do that?

This happened to me also. Check if this program wants command line parameters. It may be missing the filename of an image in the command line.

Check the code for references to "argv" etc. Those lines try to access command line parameters. Comment out this lines and hard code the name of the image file. Then run it again.

My past rebuild experience for V2.3.1 was good. But the files for V2.4.2 are very different.

Was it intended that the binaries be rebuilt in the V2.4.2 release? If so is there some documentation as to how?

I tried rebuilding with CMake and MINGW but it took only a short time compared to V2.3.1.
