Hopefully this is just a simple fix. First time setting this up and using it so I am a newbie to eclipse. I am Running Windows 7 and I am using the most rescent version of eclipse juno as of 8/8/2012 from the eclipse download site. I am using the cygwin cdt's. Through a process of following setup instructions from a few sites i have it setup at least to a point to where it will run the hello world program. But, it runs with a single error.

The Error is:
Program "${XL_compilerRoot}\xlC"not found in path

Now it also gives me a location to the issue and I have looked here with confusion to try and fix it.

Location is here:
Preferences,c++/Build/Settings/Discovery,[CDT XLC Builtin Compiler Settings] options

And i guess type is type of problem just sates:
C/C++ Scanner Discovery Problem

Now one thing I did notice, when i goto properties of the project -> C/C++ Build -> XL C/C++ Compiler (shown in C_C++_build.jpg) it shows compiler location of "/usr/vacpp/bin". I assume its referring to the cygwin folder. If it is, I do not see in the folders in my cygwin directory a vacpp folder. Which of course would explain the path error. I just would not understand though if cygwin sets up its folders based on the catagories you select, why would this folder not be created. I don't know i could be completely off too.
Just at a loss now not sure where to go. Forgive me if its already posted. I looked and will continue to look just trying to find someone that may have something posted similar to my issue. Who knows i might even be looking in the wrong spot. If more info is needed pls let me know.

XLC is an IBM compiler I believe and not part of Cygwin, which contains
GNU GCC.

I assume then that I do not need the XLC then since i am using the one from cygwin?
Why would it promt to find XLC and is there a way to disable it if i dont need it?

or do i just goto:

Window -> Preferences -> Build -> settings -> discovery and remove the CDT XLC output parser and Builtin Compiler settings? (shown in Build_settings.jpg)

I don't know whether you need XLC, but if you want to use Cygwin yoy
should select the Cygwin GCC Toolchain during the creation of your C/C++
project. It should appear in the first wizard dialog if you choose an
"Executable Hello World C++ Project" in the Toolchains listbox. If
"Show project types and toolchain..." is selected and the Cywin GCC
toolchain is not visible, the CDT has not discovered Cygwin. Then,
perhaps,
http://wiki.eclipse.org/CDT/User/FAQ#I_installed_Cygwin_on_my_PC_but_Eclipse_won.27t_find_it.
has the answer.

Don't install it?

I did - when i created the project I gave it a name and under the Project type section there was a folder called executable and under that folder was 3 selections one of then called empty project which i selected. in the toolchains i had selected cygwin gcc. But this error keeps coming up. I'll remkae it again just to make sure. If i am makeing it right and it still comes up is there a way to disable the XLC since eclipse doesnt seem to let me deselect it?

ok remade prject and now i get this - shown in (errors.jpg)

if it helps here is the project creation view - shown in (creation.jpg)

ok i guess ignore the error.jpg - i retyped it instead of copy and pasting it and they went away just have that XLC error still for some reason

OK, manually delete the error mentioning "Program "${XL....." by right
click the error and chose delete.

The other errors I do not understand, nor can I look into them as I do
not use/have Cygwin. You created the project using the "hello world" wizard?

no i didnt use the wizard just typed it in.

and beyond my comprehension i dont know why right clicking and deleting the error would fix it - shouldnt have came up with it anyhow. I ean it did come up with a warning that error messages might come back with a rebuild, but i rebuilt it 3 times since then and clean. I don't get it but Thank you for your patience. - It was driving me nuts.

If it still does not work: generate a project with the wizard, look if
it works and start from there. Configuring a project from scratch
requires knowledge.

It does not fix the error, it just removes it from the view. Does your
"hello world" build and run?

You probably created an XLC project by accident with one of previous attempts. That would activate XLC scanner discovery and generate the error message since you do not have XLC installed. After the project is deleted XLC discovery gets inactive but the error entry unfortunately still would stay in Problems view. Removing it cleans it up.
