Setting up ARM compiler (Help please :-( )

Hi
I am brand new to Open AT development and I am having some real problems setting up my development environment.
I am using V3.10 of the Open AT SDK and the IDE I am using is Visual C++ 6.0.
I can successfully install Open AT and the development tool kit.
The problem I am having is setting up an ARM compiler. When I try and build the Hello_World project from VC++ I get the following error.

Check environment settings…
Launch a full library or binary process
/cygdrive/C/OpenAT/V310/TgtGen/WmGen/mak/gen.mak:64: *** The ARMDLL environment variable is not set… Stop.

How can a successfully setup an ARM compiler??? I do not want to use a commercial compiler (ARM ADS 1.2). I understand you can use just the GCC compiler???

How can I setup my environment so that I can compile using GCC???

Any help you could give me would be greatly appreciated.

Thanks in advance.

Hi tinny !

Yes, you can use GCC compiler ! Everything is included in the Open AT installation.

Read GS_Getting_Started_with_Open_AT and TU_Tutorial_for_Open_AT pdf documents. This will help you to install, configure the environment and start a project.
