Then you can go on to use Xcode IDE later if you want to once you get started. Now you can compile and link with a really simple command like: g++ $(pkg-config -cflags -libs opencv) process.cpp -o process INSTALL TAR LIB FOR MAC OS X INSTALLIt helps if you use the pkg-config package to pick up all the necessary compiler/linker settings you need, so I would suggest: brew install pkg-config ![]() Once you have got it installed, you can start compiling and building your own project. INSTALL TAR LIB FOR MAC OS X UPDATEYou can also update all installed packages with: brew update & brew upgrade & brew cleanup You can later remove any packages you no longer want with: brew rm opencv So, for a vanilla (no special options) installation and build of OpenCV do this: brew install opencv Or brew search boost # Look for "boost" libraries Then you can find any packages you want with: brew search opencv # Look for packages called "opencv" I will not show the line here in case it ever changes and someone looks at this in a few years, but it is easy to see if you go to the link above. Then, if you want to install OpenCV on a Mac, install a package manager such as homebrew which is a matter of copying and pasting a single line from the homebrew website into your Terminal. The above is called a "Spotlight Search" and is the easiest way to find anything on a Mac. Copy and paste the following into Terminal and hit Enter/Return. Next you must install Xcode's command-line tools, so start a Terminal - by pressing ⌘+ SPACE and starting to type Terminal and when it guesses correctly, just hit Enter/Return. If you are totally new to Mac, App Store looks like this: clang or gcc or g++) and no build tools, (i.e. Without Xcode, you will have no compiler (i.e. INSTALL TAR LIB FOR MAC OS X FOR FREEI am not looking for a tutorial on how to install OpenCV or other libraries, but I am instead trying to learn how that actually works so I won't need tutorials in the future.īefore you can do any C/C++ development work on a Mac, you need to go to the App Store and download Xcode for free - it is Apple's IDE - Integrated Development Environment. hpp, executables, or a collection of everything)? Is this structure specific to C++ and OS X or is it more widespread? Also, where would the libraries like OpenCV be installed, how would clang (or any other compiler/linker) know where to find them, and what kind of files would they be (.a. I think a lot of this is done by CMake, but I don't know what CMake really does, how you would use it, or how you would then utilize the library/framework in your code. Then, after you download it, you have to build it (I don't know what build means though), and then link your compiler against it so that it can access the files? I don't know how any of this would be done, or really what this means. My understanding is that OpenCV (and other libraries/frameworks) is distributed as only the source code so that is is able to work cross-platform. ![]() I am trying to install OpenCV, but I don't know what needs to happen for it to be installed, how to check, or what really OpenCV is (Is it a library, framework, something else?). I am really confused over what it means to install (I think they are called libraries) for C++. ![]() I am trying to get my head around some basic concepts, but I can't seem to figure them out. ![]()
