HelloWorld don't work in eclipse-cdt ... !!

Question

Hi all,
can anybody tell me, what i'm doing wrong here?
i have installed eclipse-cdt with pacman and in my second try i downloaded it from eclipse.org.
I always get the same problems ..
I created a new Hello World c++ project, but i couldn't compile it successfully.
**** Build of configuration Debug for project test2 ****
make all
Building file: ../src/test2.cpp
Invoking: GCC C++ Compiler
g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/test2.d" -MT"src/test2.d" -o"src/test2.o" "../src/test2.cpp"
../src/test2.cpp:9:20: warning: iostream: No such file or directory
../src/test2.cpp: In function 'int main()':
../src/test2.cpp:13: error: 'cout' was not declared in this scope
../src/test2.cpp:13: error: 'endl' was not declared in this scope
make: *** [src/test2.o] Error 1
Looks like the compiler don't find the includes and librarys. By default the include search paths for the compiler are
/usr/inlude
/usr/local/include
Then I added to the include path
/usr/include/c++/4.3.3
and to the librarys paths
/usr/lib
/usr/local/lib
then i got this result

by the way, if i take a other short c++ project and do the "make all" on console ... it works ..
any help?
Thanks

I have the same problem here. This week I tried to install eclipse from pacman, and I also tried downloading the cdt version from eclipse.org, to my girlfriend's computer and I have the same problem you have. When I compile within eclipse, g++ can't find standard libraries. Invoking g++ from the shell, works as it should.
The strange thing is that in my main computer eclipse is able to compile perfectly.
