errors when building and just have this last one I can't figure out "***
[clean] Error 1". If you can't tell, I am a newbie ( just started a c++
class 4 weeks ago).
Any help would be appreciated, Thanks.

Hey guys,
before yelling here, look at the infos you provided.
The paste from the problems/task view is not enough, take the error
messages from the C-Build View.
I would guess, that you're makefiles clean rule looks like this:
--- SNIP ---
clean:
rm -rf helloworld helloworld.o
--- SNIP ---
First thing is, infront of rm must be a dash '-', though it looks like
the following:
--- SNIP ---
clean:
-rm -rf helloworld helloworld.o
--- SNIP ---
This will make ignore errors by executing rm-command, and the best
example for such an error is, when rm can not find the files to clean,
e.g. you build the first time and there is no helloworld.exe yet (since
you just try to build it).
Second thing is, that under Windows, executable files have an .exe
extension, which is mostly forgotten in most tutorials, even though they
claim to write the tutorial for windows users, they just copied from
somewhere else and did not read over their FAQ/tutorial again.
Though, your clean rule should look rather like this:
--- SNIP ---
clean:
-rm -rf helloworld.exe helloworld.o
--- SNIP ---
and your build rule like this:
--- SNIP ---
all:
$(MAKE) helloworld.exe
helloworld.exe: helloworld.o
$(CXX) -o $@ $^ $(LDFLAGS)
%.o: %.cpp
$(CXX) $(CXXFLAGS) -o $@ -c $<
--- SNIP ---

Thanks, I changed the makefile to the following:
>
> all: hello.exe
>
> clean:
> -rm main.o hello
>
> hello.exe: main.o
> g++ -g -o hello main.o
>
> main.o:
> g++ -c -g main.cpp

and it worked (on Red Hat 9, Eclipse 2.1.1 Linux-gtk, CDT 1.2.1).
Again, many thanks!
