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

frashman · 2009-04-14 06:51:58

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 use a build command 'make' for my C project, a 'dirty' quick fix (I maintain the Makefile myself).

frashman · 2009-04-15 09:09:58

if i disable the automatic build command and setup 'make' it's still the same result.

any other suggestion?

thx

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.

simply having Eclipse and CDT doesn't mean you have g++.
I had exactly the same problem.
Then I installed g++ and restarted Eclipse. The problem went away.
