I downloaded c++ tools to Eclipse (kepler) from:
http://download.eclipse.org/tools/cdt/releases/kepler
the usual way -> Help -> Install new software -> etc
I just realised it does not contains any compiler so i downloaded MinGW and installed it too.
My eclipse still remains unknow how to compile and run c++ projects.
Here is the pic please tell me how to configure compiler paths or something like that.
A good idea would be to find where g++ was installed then add its directory to your PATH.

I am a C++ newb. I have the Eclipse Luna IDE for Windows 10 and downloaded the Eclipse C/C++ IDE CDT 9.4 plugin. I have some code which has
#include <stdio.h>
which is giving me "unresolved inclusion". Based on my research it means I do not have some include folder. I cannot find it on my Windows machine and all the help I've found is with ubuntu or Linux-based operating systems. So how do I get this to work? How do I get the folder?
Go to project properties, C/C++ General -> Paths and Symbols and for Language GNU C you should see the compiler default include folders.
If not, you might have a path problem.
And i think This helps you!
I want to start doing some c++ but need it to be cross platform. I have found wxWidgets as a GUI solution and will use some of their SQL solutions for my program.
I tried searching the internet for how to install wxwidgets on Eclipse Mac but no luck. Haven't found anything that I can wrap my head around it.
wxWidgets is a C++ cross-platform and cross-compiler solution. It means that you don't need to install it. You can just compile it and use it to develop a software.
In order to compile this library, you should have a C/C++ compiler (clang or gcc on OSX/Mac) and their toolchain. Also if you plan to develop for OSX, you shuold have an OSX/Cocoa SDK installed (it is installed automatically with Xcode, have no idea about Eclipse).
In order to do so, you should:
Install C/C++ compiler (either with Xcode or Eclipse or any other IDE you have available).
Download latest wxWidgets release and unpack to you home diectory.
Open up a Terminal and issue following commands:
a. cd ~/wxWidgets
b. mkdir buildMac
c. cd buildMac
d. ../configure --enable-debug --with-cocoa --with-mac-osx-version-min=10.7 && make
e. ./wx-config --cxxflags
f. ./wx-config --libs
Open up Eclipse and start a new C++ project. If you are on OSX you may choose C++ bundle application.
Open the project properties and copy the results of the commands 3e and 3f to the project properties where appropriate. Consult with Eclipse manual/ML/forum to understand where to put that info.
Copy the file ~/wxWidgets/samples/minimal/minimal.cpp to you project directory and add this file to you project. Compile and run the project.
If you get stuck with any of the above instructions or get an error during compilation of either library or your project - don't hesitate to ask either here or open another thread.
Also, you can register on the wxWidgets forum at forums.wxWidets.org and subscribe to the wx-users ML.
Good luck.
I have just started to learn C++ for school, and I'm trying to download the compiler MinGW to compile my source code. However, every time I try to compile a program an error message shows up saying that zlib1.dll is missing.
This is the error message
the program can't start because zlib1.dll is missing from your computer
I have tried installing/re-installing with no luck. I don't know what's the problem here?
Can anyone please help me with this problem as I have some homework that I need to do but I can't without the compiler.
Thanks.
I had this same problem, but fixed it like this:
I ran the MinGW Installation Manager (e.g. C:\MinGW\libexec\mingw-get\guimain.exe).
I navigated to All Packages -> MinGW -> MinGW Libraries.
I checked the boxes next to mingw32-libz (dev & dll).
I went to Installation -> Apply Changes.
Now everything worked properly.
From the MinGW getting started; an automated GUI installer assistant, or use mingw-get, is available (installed as "MinGW Installation Manager") and can be used to install additional libraries and manage dependencies. For the missing zlib libraries, add the mingw32-libz libraries as required.
It seems to have been an issue previously here on super user. It seems you may be able to get them directly from the zlib website. Open Babel has some info on it being required to be copied afterwards (together with some other dlls).
Alternatives include using the mingw-w64 distros from nuwen or mingw-builds. I've never had any issue getting these up and going. They also support x64 builds.
Had same problem here, I've just used mingw-get install mingw32-libzat the cmd and it worked.
I've spent hours looking up how to fix this problem but nothing has worked. I have eclipse Indigo with CDT and ive downloaded cygwin and packages such as g++, make file, etc. When I try to execute any code I end up with the error Launch failed. Binary not found. I've also set the system path C:\cygwin\bin. How can I set up eclipse so I can use it as my IDE for c++?
Found the problem, I didn't press the hammer button to build the project first. I've only used eclipse for java and I could just hit run and everything would work fine.
Try downloading MinGW, and using those compilers. The Cygwin tools require libraries that Eclipse may not load. The MinGW executables do not require any additional environment like Cygwin does.
Also, in order to use most Cygwin executables, you need to launch the Cygwin environment first.
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.
