Hi,
After several problems with Eclipse I removed my installation and downloaded this file:

http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/juno/SR1/eclipse-parallel-juno-SR1-linux-gtk-x86_64.tar.gz

I copied the archive contents in my home directory and lauched eclipse.
I asked for a new "hellow world C++ project".
The project does not compile because the words cin and cout are not recognized.
strangely, the #include <iostream> is okay to the compiler.

I am very new to eclipse. I spent the whole day trying to get it work. Your help is more than welcome Smile

Olivier,

You'll likely want the help of the Eclipse CDT forum rather than this
one. See

Bonne chance !

That is an error message from the Eclipse static code analyzer CODAN (semantic error) not from the compiler. CODAN depends on a correct index about header files and symbols. The index seems to be incorrect in your case. Select your project and open the context menu. Select Index->Rebuild. This should fix your problem (usually the index is updated automatically).

Axel,
Many thanks for helping.
Your trick did not worked.
I played around with options in the same menu, then found that inclusion of <iostream> was unresolved.
How can I fix this ?

The include path for system headers like iostream should be found automatically by Eclipse. Did you select the correct tool chain (gcc) in Project Properties?
