I wish to install a C++ plugin for the Eclipse IDE.
I have Fedora 10 installed.

I goto
1. System-->Administration-->Add/Remove Software
2. I type 'eclipse' in the seach box and hit 'Find'.
3. From the list of packages available I select 'Eclipse C/C++ Development Tools (CDT) plugin.
3. When I hit 'Apply' I get an error message saying 'No Network connection available' The 'more deatils' tells me: 'Cannot install when offline'

But my computer IS online. I have internet access etc.

What is wrong

I'm not all that familiar with eclipse, so I don't know what package you are looking for but I would use the command line.

Here are the list of eclipse packages available:

[root@hp360-rhel5-64 ~]# yum search eclipse
Loaded plugins: rhnplugin, security
========================================================================= Matched: eclipse ==========================================================================
eclipse-ecj.x86_64 : Eclipse Compiler for Java
eclipse-jdt.x86_64 : Eclipse Java development tools
eclipse-jdt-sdk.x86_64 : Eclipse JDT Source
eclipse-pde.x86_64 : Eclipse PDE
eclipse-pde-runtime.x86_64 : Eclipse PDE runtime plugin.
eclipse-pde-sdk.x86_64 : Eclipse PDE Source
eclipse-platform.x86_64 : Eclipse platform common files
eclipse-platform-sdk.x86_64 : Eclipse platform Source
eclipse-rcp.x86_64 : Eclipse Rich Client Platform
eclipse-rcp-sdk.x86_64 : Eclipse RCP Source
eclipse-sdk.x86_64 : Eclipse PDE Source
libgcj-src.x86_64 : Java library sources from GCC4 preview
lucene-devel.i386 : Lucene source code
lucene-devel.x86_64 : Lucene source code

I'm assuming that you are looking for the BOLDED package and if so, type the following to install:

sudo yum install eclipse-jdt

(If that is not the package then replace the "eclipse-jdt" with what package you are wanting...)

Let us know the error message that is given by that and maybe we can help you better.

sudo yum install eclipse-cdt.i386 did the trick

Thanks for your help, I don't know why eclipse is not detecting internet.
