I want to install open cv library and i am using Dev c++ compiler. I tried several times to install open cv, but it doesnt work properly. i have read some documents which says, it is necessary to intall cmake first. but, i tried without it. can anyone guide me to install open cv please (please give me procedure, step by step).
I would answer this properly, but, here is my very important recommendation.
Don't use Dev-C++!
It isn't really maintained (last release was in 2005), it is mostly meant for beginning programmers (I learned from it myself), its a pain to do anything it was not meant to do.
I would suggest Visual C++ Express, Eclipse CDT, or Code::Blocks. If you have a computer that's pretty new, then, Netbeans.
If you are willing to use these technologies, a lot of people will gladly give you answers.
I wrote a procedure for Code::Blocks on Win32 a little while back.

I just learned the basics for git bash and GitHub, and I want to start using a repository for a simple console-based text game in C++ that I will be making. I have a MacBook laptop that I use to code on the go in XCode, and when I am home I use my Windows desktop in Visual Studio.
My question is "How do I run a C++ program from GitHub for both of these IDE's after I have cloned it?"
Should I just get the same IDE for both computers, like Eclipse? I've done quite a bit of research, but everything seems super complicated. I am hoping that there's an easier way, as I'm just a hobby coder. I'm definitely willing to learn; I just hate copying and pasting commands without understanding what they do. Any help is appreciated :)
Edited: Clarified that I know how to clone. The running part is what I don't know how to do.
There really are several ways to do what you're asking.
Store the project files with your repo, usually in a dedicated folder
msvc (with version)
xcode
makefile
qt creator
kdevelop
etc....
generalize the c++ with another build-system like CMake
The first option will/can get annoying but it is usually where most people starting to learn to program go. It isn't too bad so long as you realize you'll probably have problems sharing your project as no one has 'quite' the same exact setup as you.
The second option is where most projects usually end up. You need to learn the intricacies of something like CMake but once you learn, projects can be made for almost any IDE/environment.
I'm trying to compile cairo into a lib file using Mingw. I've downloaded the cairo, cairomm, and pixman source packages, but I can't figure out where to go from here. The INSTALL help file talks about a bunch of scripts that I can't seem to run or even find ('./configure', 'make', 'make install'). Googling the issue is bringing up nothing helpful.
I feel like this is a noobish question to ask. I've only recently started getting into the C++ side of programming (coming from Java/C#), and this is the first time I've had to compile an external library before using it. The shocking lack of explanations on the process makes me wonder if there was some chapter of a tutorial somewhere I was supposed to read that makes this whole process a complete no-brainer.
I think this project isn't supporting building with Mingw.
There are build instructions here for building with Visual Studio (which can be downloaded for free as the Visual Studio Express Edition from MS Website: http://www.visualstudio.com/en-US/products/visual-studio-express-vs
Build instructions here:
http://cairographics.org/end_to_end_build_for_win32/
It's probably possible to make this work for MingW, but you will have to make it work yourself, which may be a bit of a long step for someone who is new to compilers and build scripts in general.
I would like to start programming in OCaml. As I am a Windows user, I understand that it is preferred to do so using the OCaml plugin for Netbeans.
I have downloaded the aforementioned plugin from the following link: http://ocamlplugin.loki-a.com/ocamlplugin/updates/ . I have installed the plugin into Netbeans as instructed. I managed to open a project but even the sample "Hello World" won't run.
I then tried to install the OCaml IDE from here: http://ocamlplugin.loki-a.com/index.php?title=Main_Page#Download_2 , but it still wouldn't run anything.
I am not interested in working with Eclipse because that would include downloading Cygwin.
I would appreciate a simple solution. Thank you! :)
I would suggest OCaIDE under Eclipse, if you stick to Windows anyway.
But I don't understand your reluctancy to use cygwin, especially when there is such nice step-by-step tutorial for configuring cygwin for OcaIDE and Eclipse.
Another option, which I haven't tried but would strongly suggest you trying, is Sublime Text 2. It supports OCaml and is a very popular cross-platform text editor. But since I haven't tried it, I would not be able to provide you with details about it. Although it comes with a cost, you can evaluate it for free without time limit.
TypeRex has been my favourite for OCaml so far, and you can now use Emacs in Windows, so with some workaround in cygwin you can use TypeRex in Windows.
Another option is to use VirtualBox, install a normal linux distro and use Typerex+Emacs inside it. It is also not complicated, as it takes 1 hour to config at most.
The ocaml links that you gave have not been touched since 2009 (4 years ago). That probably means the odds of them running with the current NetBeans are equivalent to the proverbial sphere of solidified water in the Christian place of eternal theological punishment.
Since you are asking about running under Cygwin, it sounds like you want a Linux version of Eclipse as well. Eclipse runs quite well under Win7, at least, and under Mint (I use them under both) However, all my attempts to get ANY OCaml IDE running under either system have been borged (resistance is futile, and depends and capacitance anyway).
So, under Mint 15, emacs and vim (the old standards) work well as text editors. I wish I could suggest anything else.
Good luck!!!
By now, another option has appeared for Windows 10 users wanting to use OCaml: the Windows Subsystem for Linux.
Basically, what it does is that it allows you to run Bash and any non-GUI Linux program on your PC. Once installed, you can install OCaml and OPAM with apt-get and you're good to go.
As far as I am concerned, I use Windows 10 on my desktop PC, and I haven't had any inconvenience with WSL yet.
I personally use Merlin/... which is are plugins for emacs. But I can understand that you dont want to use emacs. I have been told that the support with Visual Studio Code is supposed to be quite good, especially when using it together with the builtin console. Also for smaller things there is Ocamltop but I have now idea how the Windows support is. In the end I suggest, using the Linux Shell on Windows as RichouHunter suggests.
A group of students and I are making a C++ game, but they have Windows and I have a Mac is there something we can use to share code between the systems?
I know Eclipse will work but I get Unresolved conclusion: <iostream> as an error. If anyone can help with that it would be great.
If you want something to actually "share the code" with, I would recommend git using github as the remote location. Its free and easy to use.
If your question is about the code not working, make sure you have X11 configured properly, and have the Eclipse C++ plugin installed.
And I would also recommend using XCode as your editor instead of Eclipse. It has a much better environment for C++, IMHO.
Hope this helps.
Personally I'd recommend setting up a cross-platform build process using something like CMake (http://www.cmake.org). CMake in particular will generate platform-specific project files for you -- so your friends could be working in Visual Studio and you could be working in Eclipse or XCode, with no problems at all (of course, you'd have to write portable code... :))
As far as sharing code and version control goes, I agree with Jon that something like git is ideal.
We build our Windows+Mac+Linux apps using Qt, which includes a nice build system (qmake) and cross-platform APIs (so the same code will run on all OS's) and an IDE (which I haven't used but I hear is okay).
With multiple developers you'll definitely want some sort of source-code-management system as well, git and svn are both good choices there.
I have a friend who is trying to make the switch to Linux, but is hung up on the apparent lack of debugging/IDE environments for C++, especially as they relate to template programming. He has been using visual studio for years and is maybe a little spoiled by their awesome IDE. Does anyone have any good suggestions for an environment where he can, under Linux, develop and debug with all of the usual things (Breakpoints, line highlighting for compilation errors, step in/over/out/etc, etc) that he's accustomed to? Thanks!
How about Eclipse + CDT ?
Although many people think of it as a Java IDE, he could try NetBeans. I've used it on Windows for C and C++ development without a problem, and I know NetBeans is supported on Linux, so it would be worth a shot.
It looks like most of the features he wants are included in the C/C++ development toolkit, including integration with GDB, a profiler, and more.
Visual Studio is good, indeed.
On the free side:
Qt Creator is getting quite good too, it's worth a try. There are advantageous by-products coming from the Qt framework:
huge library - not only to build GUI applications but for other domains as well
portability on multiple platforms
A version 1.3 beta is available as a preview of the upcoming release but the current 1.2.1 is already all you need to manage projects.
Eclipse has already been mentioned, it's a very good environment offering many plug-ins (Mylyn, SVN, ...).
MonoDevelop somewhat supports C++ (more and more, I didn't check the latest version).
I've used Eclipse for C/C++ and it's pretty useful. It's also used at ACM ICPC World Finals http://cm.baylor.edu/welcome.icpc
I'd recommand Code::Blocks (but use a nighty build). It can be coupled with gdb to enable step by step debugging and all that stuff.
Not exactly an IDE but SublimeText 2/3 is available on Linux now. There may be a debugger plugin for it too, who knows.
Edit
Here's a gdb plugin for SublimeText
I havn't explored it personally, but Emacs has a C++ development addon that looks very much like a full IDE.
About 7 years ago I used KDevelop that was shipped with KDE. I found it quite good back than, and I hope it also improved with the time. I found it quite comparable to VC++ 6 at this time.
It also contains Qt support, if you are in need for some GUI toolkit.
Depends, Code::Blocks is good, Eclipse is very nice too, but you will need a very good computer. In my opinion the best choice iss gcc, gdb and ViM or Gedit.
My buddies from work use Eclipse + Scons, they also use Valgrind(spelling?) for tracking memory leaks and such.
Many of the IDE features you listed were debugger features. The ddd (Data Display Debugger) debugger is quite a nice GUI wrapper for gdb, allowing graphical representation of data structures, a non-crappy source listing window (ie. unlike the l command of gdb where you don't get context), and also allows you to use any and all native gdb commands directly if desired.
Have a look at CodeLite. It's available for Ubuntu and Fedora out of the box and even for Windows and Mac. So you can have the same IDE on different platforms.
We tried Eclipse and NetBeans but left them due to their huge CPU and memory usage. We have a development server and all the developers connect to it via RDC. Thats why these IDEs miserably failed in our model.
So, we looked for some native IDE. Found CodeBlocks to be very good and super fast. We sort of settled on it but later found CodeLite and liked it better than CodeBlocks.
I just seeing this question after 12+ years. AnyHow I just writing my answer. I personally use Quincy IDE for C and C++ development. it is very lite weight and debugging watch list is very much good and easy to use. I'm just attaching the link to the site. try it.
But you have to install it with wine.
