I just installed Ubuntu 12.10, and I tried to install Eclipse and C++, but I failed miserably.
I started with an installation from the Software Center, Eclipse worked, but only in Java. Then I started googling for installation guides and tutorials, but after hours of downloads and installations, the C++ in Eclipse still doesn't work.
So now I have two questions:
How do I clean up this mess?
Actually, how do I know if there is a mess?
According to the Ubuntu Software Center, Eclipse is installed and has three add-ons.
How do I know if the other installations of other Eclipse versions/packagings overwrote each other or if I have multiple installations?
How do I install the latest version of Eclipse and C++ in Ubuntu 12.10?
There is a package called eclipse-cdt in the Ubuntu 12.10 repositories, this is what you want. If you haven't got g++ already, you need to install that as well, so all you need is:
sudo apt-get install eclipse eclipse-cdt g++
Whether you messed up your system with your previous installation attempts depends heavily on how you did it. If you did it the safe way for trying out new packages not from repositories (i.e., only installed in your home folder, no sudos blindly copied from installation manuals...) you're definitely fine. Otherwise, you may well have thousands of stray files all over your file system now. In that case, run all uninstall scripts you can find for the things you installed, then install using apt-get and hope for the best.
I used (the suggested answer from above)
sudo apt-get install eclipse eclipse-cdt g++
but ONLY after then also doing
sudo eclipse -clean
Hope that also helps.
I also tried http://www.eclipse.org/cdt/ in Ubuntu 12.04.2 LTS and works fine!
First, I downloaded it from www.eclipse.org/downloads/, choosing Eclipse IDE for C/C++ Developers.
I save the file somewhere, let´s say into my home directory. Open a console or terminal, and type:
>>cd ~; tar xvzf eclipse*.tar.gz;
Remember for having Eclipse running in Linux, it is required a JVM, so download a jdk file e.g jdk-7u17-linux-i586.rpm (I cann´t post the link due to my low reputation) ... anyway
Install the .rpm file following http://www.wikihow.com/Install-Java-on-Linux
Find the path to the Java installation, by typing:
>>which java
I got /usr/bin/java. To start up Eclipse, type:
>>cd ~/eclipse; ./eclipse -vm /usr/bin/java
Also, once everything is installed, in the home directory, you can double-click the executable icon called eclipse, and then you´ll have it!. In case you like an icon, create a .desktop file in /usr/share/applications:
>>sudo gedit /usr/share/applications/eclipse.desktop
The .desktop file content is as follows:
[Desktop Entry]
Name=Eclipse
Type=Application
Exec="This is the path of the eclipse executable on your machine"
Terminal=false
Icon="This is the path of the icon.xpm file on your machine"
Comment=Integrated Development Environment
NoDisplay=false
Categories=Development;IDE
Name[en]=eclipse.desktop
Best luck!
I was in the same boat. Installed Eclipse, realized need CDT.
sudo apt-get install eclipse eclipse-cdt g++
This just adds the CDT package on top of existing installation - no un-installation etc. required.
http://www.eclipse.org/cdt/
^Give that a try
I have not used the CDT for eclipse but I do use Eclipse Java for Ubuntu 12.04 and it works wonders.

The objective is to compile a C++ program with Boost.Python in Eclipse on the OS on Linux Mint 18. In particularly, we want to run the template program:
#include<boost/version.hpp>
#include<boost/python.hpp>
#include<iostream>
using namespace std;
int main() {
cout << "My first boost program with version: " << BOOST_LIB_VERSION << endl;
return 0;
}
This personally took me quite a while to get working, so the tutorial below should serve as a one-stop-shop reference for anyone in a similar situation. Note on software used:
Boost version: 1.62.0
Python version: 2.7.12
OS: Linux Mint 18 Xfce 64-bit
Eclipse version: CDT 9.1.0 for Eclipse Neon.1
Installing Eclipse CDT
Make sure that you have Java installed. For the Java JDK (if you want to also develop Java programs), run:
sudo apt-get install default-jdk
To simply run Java programs (such as Eclipse), you can install the lighter Java JRE:
sudo apt-get install default-jre
Both JDK and JRE will work, but JDK takes up more space.
Go to CDT download webpage and download the Linux 64-bit file eclipse-cpp-neon-1-linux-gtk-x86_64.tar.gz
Assuming you downloaded the file in ~/Downloads/, run the following command to unpack ("install") Eclipse into the /opt/ directory:
sudo tar zxvf ~/Downloads/eclipse-cpp-neon-1-linux-gtk-x86_64.tar.gz -C /opt/
To create a desktop launcher icon, run
sudo gedit ~/.local/share/applications/eclipse.desktop
and in the text editor copy-paste:
[Desktop Entry]
Name=Eclipse
Type=Application
Exec=/opt/eclipse/eclipse
Terminal=false
Icon=/opt/eclipse/icon.xpm
Comment=Integrated Development Environment
NoDisplay=false
Categories=Development;IDE;
Name[en]=Eclipse
You now have Eclipse installed, but you don't need to run it yet, just keep reading and following the instructions :)
Installing Boost
The instructions are more or less given here, but for the sake of cohesion I write them here.
Download boost_1_62_0.tar.gz
Assuming you downloaded the file into ~/Downloads/, run the following command to unpack Boost into the /usr/include/ directory:
sudo tar zxvf ~/Downloads/boost_1_62_0.tar.gz -C /usr/include/
It's as easy as that - you now have Boost... but that's not all yet. Read on :)
Building Boost.Python and Boost.System
The Boost libraries Boost.Python and Boost.System must be built before they can be used. Here's how you do this:
Go into the Boost directory in your Terminal:
cd /usr/include/boost_1_62_0/
Run the command:
sudo ./bootstrap.sh --prefix=/usr/local
To build Boost.Python and Boost.System into the /usr/local/lib folder, run:
sudo ./b2 install --with-system --with-python
once the command has finished, you will find libboost_system and libboost_python (with various file endings) in /usr/local/lib
That's it for building the necessary Boost libraries. Note that any other Boost library that needs to be built can be done in the same way.
Preparing Python 2.7
Linux Mint 18 comes with Python 2.7 pre-installed. For me, running the command python --version returns the output Python 2.7.12. I'll assume this is the same for you - but probably it doesn't make a difference what the version is. However, to get our objective of the C++ program with Boost.Python to build and run, you have to execute the additional command:
sudo apt-get install python-dev
which places some additional necessary files (particularly pyconfig.h) into /usr/include/python2.7.
Installing Linux GCC
Linux GCC allows you to compile C++ programs. To install everything necessary, simply run:
sudo apt-get install build-essential
Making our program run in Eclipse
Now we've got everything configured to be able to write, build and run our program in Eclipse. So, let's do it!
Run Eclipse, either from the terminal (either by using the desktop icon we've created or by running /opt/eclipse/eclipse in the Terminal).
If it's your first time running Eclipse, you'll be prompted to choose a workspace (basically, a folder where all Eclipse project files will be stored):
Now go to File -> New -> C++ Project and enter the following and click Finish (you can use whatever Location you wish, including the default location (i.e. the one of your workspace)):
Now go to File -> New -> Source File, enter the following and click Finish:
In the main.cpp file that automatically opens in the editor, type in the program that we want to compile (note that I customized my Eclipse layout, so it looks different from the default layout you might have):
Now the secret sauce. Go to Project -> Properties -> C/C++ Build -> Settings where you will see:
Go to GCC C++ Compiler -> Includes and, using the little icon that looks like a folder with a green plus sign, add the following Include paths:
Go to GCC C++ Linker -> Libraries and add the following Libraries and Library search paths:
Press OK to close the Project Properties window.
Back in the main Eclipse window, first click the hammer icon to build the project, then the green play icon to run it (both buttons are highlighted in the below screenshot). In the console view you will first see a successful build, then the Terminal output of our program:
That's it! We've achieved our objective of building and running a C++ program with the Boost.Python library included. That's the end of this tutorial, I hope it helped you :)
Hi I've tried to install the latest codelite but when I try to open it, it doesn't. I followed the instructions on the site but no luck.
I'm using openSUSE 13.2 64-bit
You probably need to install the wxWidgets runtime libs, which were supposed to be included in the CodeLite package but weren't.
openSUSE don't seem to have a meta-package for these, and there are a confusing number of choices, most of which will be wrong for you. However if you ask yast to install libwx_gtk2u_webview-suse-3_0-0 I think you'll find that will depend on the rest of the correct libwx* family.
At the time of this writing, you can install codelite and wxwidget in opensuste in a straightforward method. Just go to the
opensuse software repository and search for codelite. After representation of the results press on the button
Direct Install
to let you install the package on your machine.
I'm on Mac OS X Yosemite 10.10.2. As far as I know, wx-widgets were preinstalled on older versions on OS X (probably that's why google search doesn't help), but that's not the case anymore. I need to get started on a C++ project using wx-widgets, using any IDE (Eclipse, Codelite, or whatever is best). However, I simply cannot get wx-widgets to work. After a workaround I was able to compile on my machine wxWidgets-3.0.2. I called from terminal make and make install, but the libraries seem to not be correctly installed. Indeed, if I create a project on Codelite I get many "wx-config: Command not found" errors. Can someone help me to get me started on installing the libraries and creating a simple project that includes wx-widgets?
I use homebrew which is installed by copying and pasting one line from the homebrew website.
Then, the installation of wxWidgets is simplicity itself with:
brew install wxmac
Any problems, you just call the doctor with
brew doctor
Now you have a proper package manager you can install ImageMagick, GNU Parallel, GNU awk, Oxygen, webkit2html, zeromq, tree, SDL, Redis, sqlitebrowser, pandoc, exiftool, ffmpeg, 7zip, awscli, etc...
You can then compile your wxWidgets programs with
g++ `wx-config --cxxflags` -o sample sample.cpp `wx-config --libs`
I can successfully compile and install wxWidgets on Yosemite with these commands:
- Get the latest sources of wxWidgets 3 from wxwidgets.org and unpack them.
- Move the unpacked directory someplace where you want to keep it.
- Open a terminal and change into the wxwidgets directory.
- Create two directories: build-release and build-debug (don't rename those!)
- Change into wxwidgets/build-release
- Run
../configure --with-osx_cocoa --disable-shared --with-opengl --enable-universal-binary=i386,x86_64 --with-macosx-sdk=/Developer/SDKs/MacOSX10.6.sdk --with-macosx-version-min=10.6
- Run make, then sudo make install
- Change into wxwidgets/build-debug
- Run
../configure --enable-debug --with-osx_cocoa --with-opengl --enable-universal-binary=i386,x86_64 --with-macosx-sdk=/Developer/SDKs/MacOSX10.6.sdk --with-macosx-version-min=10.6
- Run make, then sudo make install
Be aware that these instructions are for compiling against the Mac OS X 10.6 SDK, which I have at /Developer/SDKs/MacOSX10.6.sdk. You can try to omit the --with-macosx-sdk parameter altogether, which will compile using the latest SDK. Also ensure that you have Xcode and the command line developer tools installed.
These commands will install static libraries for the release build and shared libraries for the debug build. You can change this by supplying or omitting the --disable-shared parameter.
The instructions for building and installing wxWidgets are included in the distribution and can also be viewed online.
If your IDE doesn't find wx-config, you must not have the location where you installed it (/usr/local/bin) by default in your PATH. Add it there to fix this.
Like suggested by VZ, you must change your PATH.
But not the variable PATH in your environment Windows but the variable PATH in your C++ project. It's strange but maybe it's different.
Go into (for eclipse) :
C/C++Build->Environment->PATH (add the path of wx-config in the beginning).
Press : Apply, OK and build the project.
I think is strange that Eclipse don't update the PATH after rebooting the OS. Maybe we must add an option to Eclipse for building WxWidget and force Eclipse to update the PATH, but I don't know it.
This change work for me.
Eclipse / MinGW-MSYS / WxWidget 2.8
I downloaded Ubuntu 14.04TLS recently.
I'm very new to the Linux environment as I'm a Windows user. I don't really know how to install application on the Linux environment.
please I need help on how to get code blocks with MinGW for Ubuntu and how to configure it.
Also I need help on how to install gtkmm and configure code block to locate it.
I don't know if the same way we do
Open Project > Build Options…
Select your project.
On the Compiler settings tab, select Other options
and add this to the field:
pkg-config gtkmm-3.0 –cflags
Select the Linker settings tab and type the following
line in the Other linker options text area:
pkg-config gtkmm-3.0 –libs
that we will also do for Ubuntu. Also are we doing anything about environment variable.
also if you can recommend tutorials that I can use to understand the Ubuntu environment properly.
thank you once again
install code blocks on linux ubuntu (mingw is windows version of gcc)
sudo apt-get install codeblocks build-essential
install gtkmm
sudo apt-get install libgtkmm-3.0-dev
This is everything you need to know:

In Ubuntu, there is a package called uuid-dev. To install and use it, I just need to run apt-get install uuid-dev. However, in MinGW, I couldn't install this package using mingw-get install.
May I know what are the basic steps to port a C++ application/library from Ubuntu to MinGW?
It might already support compilation under MinGW. Generally you would download the source, unpack them and run ./configure and see what happens.
Give that a try and get back to me.
