Ubuntu Eclipse CDT related operations

1. Add Elipse CDT to the left program launch bar

Enter under/usr/share/applications

sudo gedit eclipse.desktop, then enter

[Desktop Entry]
version=1.0
Name=eclipse
Exec=/home/ck/eclipse/eclipse
Terminal=false
icon=/home/ck/eclipse/notice.xpm
Type=application
Categories=development

Save, sudo chmod 777 eclipse.desktop, all right words will see the Eclipse icon under this folder

Drag the icon to the left of the program launch bar to

Problem

1) There may be spaces on the path of Exec and Icon, which need to be wrapped up with "". Sometimes the use of "" or there will be problems, it will be more than a few times, on my machine, the path has a space does not seem to be a problem

2. The Eclipse CDT code completion problem

Unable to prompt function because headers is not found

Add two variables into Windows, Preferences, c/C + +, Build, environment

Cplus_include_path:/usr/include/c++/4.8(my gcc version, my own GCC version can be viewed under the/usr/include/c++ folder)
C_include_path:/usr/include

Even so, I found myself unable to use the code hints in c++11, such as unordered_map, without a hint at all.

I remember when I used to wear the CDT, it was still possible, and probably the reason for UBUNTU 14.04.

3. Configuration using the C++11 feature under Eclipse

Right-click Project, select Properties, c/C + + Build, Settings, GCC C + + Compiler, Miscellaneous, add-std=c++11 under other flag
