I have installed the latest versions of OpenCV and Eclipse CDT, but not able to make OpenCV to be used within Eclipse CDT.
Any ideas on how can I do that?
Thanks a lot.
What platform?
See http://opencv.willowgarage.com/wiki/EclipseOpenCVLinux ?
Otherwise you generally run cmake in the top of the opencv source dir and select the compiler you want, for Eclipse that's possibly mingw (unless there is an eclipse specific version)

In my professional computer, I have minGW 4.5.2 installed. Eclipse CDT works perfectly with it.
But I want to test some C++11 features. So I copied my minGW 4.8.x folder from my personal PC.
My problem is that eclipse uses libraries from the old minGW (witch is the PATH).
I'd want to set eclipse up to use the new version of minGW.
I know how to change the g++ used for compiling/linking but not the include libraries.
Any idea ?
Thanks a lot.
PS : I can't change the PATH in my professional computer. I run Windows 7
You can try creating a batch file the following code, assuming the MinGW you want to use is in C:\MinGW :
set PATH=C:\MinGW\bin;%PATH%
start eclipse.exe
I installed Eclipse for C/C++ Developers.
After installing it I also installed PyDev.
I managed to create a C++ project (The Hello World project that comes with it). But I cannot compile/run it.
When I created the project there was nothing in the toolchain list. So I think I will need to install a toolchain. But I cannot find anything. I need someone to help me with this please.
I am using 64 bit Windows 7.
No compiler, no executable.
Check MinGW
This is one of the first results i got in google for eclipse and mingw:

You need to install not only Eclipse CDT, but also a C/C++ compiler for Windows, like minGW.
Try installing TDM-GCC from http://tdm-gcc.tdragon.net/ . This should have you up and going with a compatible GCC setup under Windows in a snap.

You have to manually setup Eclipse.
Check this blog post.
I'm trying to get eclipse to work with MinGW.
I've done the following:
Downloaded CDT for eclipse.
Installed MinGW.
Added C:\MinGW\bin to my path.
Opening a command prompt (CMD) and typing g++ or alike works fine.
I run eclipse, create a "New C++ Project", and only get the option saying "other toolchains".
There's a MILLION tutorials out there saying eclipse should identify MinGW on its own. It doesn't, and I don't know what to do. I've tried reinstalling everying in just about every order posible. Still no luck.
I've also noted some tutorials say something about creating a "Managed C++ Project". I've no such option, all I get is "C++ Project" and "C Project"
edit:
I have eclipse ganymede, windows x86_64, version 3.4.2
http://download.eclipse.org/eclipse/downloads/drops/R-3.4.2-200902111700/index.php
Running the "Eclipse IDE for C/C++ developers" fails, since there's no x64 version for windows. The x86 version requires x86 JAVA installed as well, and installing two versions of java, gave nothing but trouble in the past.
The instructions for setting up MinGW in Ganymede are located here.
The following are instructions and
links on how to install the current
version of MinGW. Note that these
links may become inaccurate over time
as new versions of MinGW components
are introduced. Please check the MinGW
File Release section for the latest
versions.
Download and run the MinGW setup program, MinGW-5.1.3.exe.
Select download and install the MinGW base tools and the g++ compiler.
You may select the Current or
Candidate version of these tools. You
may also install any of the other
available compilers as well.
Do not install the MinGW Make feature as the MSYS version of make
from step 5 is a more complete
implementation of make.
The MinGW setup program currently does not install the gdb
debugger. To install the debugger,
download the file from the following
location: gdb-6.6.tar.bz2
Extract the contents of the file gdb-6.6.tar.bz2 to the same location
where you installed MinGW.
If you want to use Makefile projects, download and run the setup
program from the following location:
MSYS-1.0.10.exe. MSYS provides an
implementation of make and related
command line tools. This is not
required for other types of projects
with the MinGW toolchain, which use
CDT's internal build tools to perform
the build.
Following this process resolved any problems I had.
I had the same exact problem with Eclipse Galileo and CDT 6.0.1. It turns out that CDT only recognized MinGW when it's located under c:\mingw. I had it in c:\msys\mingw so that was the problem. After I changed that everything worked fine.
The distinction between managed make projects and makefile project was removed in CDT 4.x, I think. Now there is only one type of project, but you can select different builders. CDT includes an internal builder which does not use makefiles and another one which does.
First, save yourself the effort of "reinstalling in every order possible". That is also known as trial-and-error, and will only make you more frustrated. Apply the normal problem-solving skills you have as a programmer.
Given that you have MinGW installed, what happens if you download "Eclipse IDE for C/C++ developers", start eclipse.exe, and try to create a C++-project with a MinGW toolchain?
EDIT: remember: the key in getting help with problems like these is to produce a minimal example which fails. Also, it would help if you provided URLs to the packages you installed (MinGW, Eclipse, etc.).
EDIT: I just installed CDT using the Ganymede update site, downloaded and installed MinGW from here, and restarted Eclipse, and everything worked fine. I know that doesn't help you, but it does prove that the toolchain detection isn't completely broken. Something is weird on your side.
You could try Wascana Desktop Developer. Its a distribution of Eclipse CDT configured specifically for developing on Windows.
I had the same problem (i.e. Eclipse not finding MinGW on the PATH) after I removed some of the unused files/folders from MinGW. It was ~600 MB and I was tasked to trim it down before adding to source control. I got it down to a workable ~200 MB. When I tried to re-create an Eclipse workspace afterwards, MinGW disappeared from available toolchains. It reappeared after I put the original MinGW install on the path.
HTH
I've been trying to use CDT with Eclipse 3.4 under Windows XP with cygwin.
What do I need to do, in order to get startet?
I used "eclipse-cpp-ganymede-SR1-win32.zip" found on the Eclipse homepage.
Edit:
The main problem is, that I cannot compile and run the code.
In the run configuration, I tried gcc.exe for the C/C++ Application:
After adding the path of make.exe to my $Path, and starting from scratch, it works perfectly.
I finally found. Thanks guys.
After downloading and unpacking "eclipse-cpp-ganymede-SR1-win32.zip", you need to install either Cygwin or MinGW.
Make sure the compiler (e.g. gcc.exe) and make.exe is on your $Path.
Start Eclipse and everything should work fine.
If you want to use Eclipse/CDT on Windows, you should consider using Wascana Desktop Developer, a CDT distro specially targeting Windows hosts.
According the the CDT Downloads page:
As a minimum, you need to install the Eclipse Platform Runtime before installing the CDT
So adding the CDT Ganymede update site to your current eclipse 3.4 configuration should be enough for you to install CDT.
After that, do you have any error message ?
For instance, there can be some eclipse.ini-related issues when using this package.
For me the package you downloaded worked from start. However I was using it with MinGW instead of Cygwin.
I am using it also for QT4 development together with QT Integrator.
I use MinGW, though I note that the documentation says you can use Cygwin. I would have a look through Max Berger's CDT guide to troubleshoot the problem.
you can install both Cygwin and MinGW in your system. gcc and make available with Mingw seems to be suitable better for native windows build. If the PATH environment is set to paths of Cygwin [and/or] MinGW Eclipse project wizard asks you select one . Either Cygwin or MinGW.
For MingW, you may need to download gdb as well, if you need to debug your application
