includes and unresolved symbols problem on ubuntu [message #759241]

Hello.

my problem is, whem I create a hello world c/c++project on eclipse, eclipse does not find the standart includes, so symbols like cout, cin and so on, are not resolved.

I'm able to fix this by manualy seting the librarys path, but i need to do this in every single project. is there a way to make eclipse do this manualy for me? i tried for up to 3 hours and could not find a solution.

on windows it works just fine, is just on ubuntu that is does not detect the librarys.

I'm not a expert on linux.

Sorry if bad english and thanks in advance. Smile

Do you use a non-English locale on your Ubuntu?

Yes, I'm not using the English language in my Ubuntu ...
Or have I misunderstood the solutions or they do not work.
Could you describe them more understandable (step by step)? Please.

You can either download a nightly build of CDT that has this bug fixed or create a shell script to start Eclipse.

#!/bin/bash
# english gcc output
export LC_ALL=en_GB.UTF-8

Could you give a link to download a nightly build
A script is still not working ... The problem remains, I do not know why.

The script will work so:

Write the script in a text editor.

Instead of the last line "eclipse &", write "./eclipse &".

Save the script in the directory where the file "eclipse" is. Name the script e.g. "start_eclipse.sh".

Click with the right mouse button on the file "start_eclipse.sh". Choose "properties".

In the tab "access rights" set a tick at the option "file execute as program".

I even installed eclipse helios there is a similar problem. When I create the project is created without includes. And it emphasizes the inclusion of the yellow line. When I add includes their own hands, everything is good.

I just tried to reproduce this as follows:

1) install eclipse indigo sr1 with cdt from
eclipse.org/downloads/packages/eclipse-ide-cc-developers-includes-incubating-components/indigosr1
2) start eclipse, do New / C++ Project / Hello World Project
3) do Window / Show View / C++
4) Hello should be showing in the project explorer; open it and look at hello.cpp
5) check whether there is a bug mark next to the #include <iostream>

When I do this in a fresh workspace, it works fine.
I do have a simple C/C++ project that has the problem you describe, so try creating a fresh workspace and see if a fresh hello project in there works ok.

In the good hello project, the properties of the hello project, under C/C++ Build,
show
Build Variables
Discovery Options
...

In the bad project, the properties of the hello project do not have
a C/C++ Build folder; instead, it has top level folders C/C++ General,
C/C++ Include Paths, C/C++ Make Project, and C/C++ Project Paths.
I can't quite figure out why they're different. (Hmm. It's possible
the bad project was generated with cmake.)
