I installed Eclipse Mars using Oomph installer on Centos 7. How do I uninstall it cleanly?
As root you could use whereis and locate to find all the directories or files where things are, and then remove them one by one.

So I decided to install a c++ compiler for Windows and thus downloaded the MinGW installer. Once I opened it, I saw a number of packages and checked all the "C++ compiler" packages (am I using the right terminology here?) for installation. I also saw other stuff like "mingw32-base" and all. What does this do? Should I install it? Also, what is the difference between mingw and mingw32?
If you don't need additional packages you shouldn't install them.
But MinGW is a bit outdated. It's better to switch to MinGW-w64, which exists for both 32-bit and 64-bit Windows.
You can get MinGW-w64 either by installing MSYS2 and installing via its package manager (pacman), or - if you don't need the additional MSYS2 shell and just want to compiler tools - you can get a standalone package from https://winlibs.com/ and just unzip it.
I am setting up Eclipse CDT for C++ and I installed the GCC compiler from equation.com. I installed it and the code wasn't updating so i decided to re-install. I deleted the MinGW folder and tried to run the installer again and now getting an error from the installer "System cannot find the file specified".
Also any help on uninstalling Code::Blocks as they are the same category of packages without magic uninstalling would be great.
Background Info: I am running Eclipse Mars and Windows 10
I'm going to list out all the steps I've taken so far:
Download MinGW
Install MSYS installation for MinGW Developers (I don't think I needed this?)
Install mingw32-base
Install mingw32-base
Install mingw32-gcc-g++
Install msys-base (Don't think I needed this either)
Add MINGW_HOME Environment Variable and MINGW_HOME\bin to Path.
Check versions of gcc, g++, and gdb (all showed they were successfully installed)
However, when I open Eclipse I get two errors indicating that g++ and gcc are not in my Path.
How do I fix or get around these errors?
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.
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
