Hi!

I’m d/l lastest version of OpenAt  
[wavecom.com/media/files/part … \_v4.00.zip](http://www.wavecom.com/media/files/partners/open_at_privilegied/Open_AT_SDK_v4.00.zip)

After unzipping, i’m installed OpenAT and Dev. Tools.

Now i’m try to build sample Hello World!  
I’m do all with TU\_Tutorial\_for\_Open\_AT\_V4-00\_rev002.pdf  
but when i’m selected Hello\_World\_rte project as active and try to duild it from VC. I have this message:

--------------------Configuration: Hello\_World\_rte - Win32 Debug--------------------  
Compiling…  
Error spawning cl.exe

Hello\_World\_rte.dll - 1 error(s), 0 warning(s)

Does anybody know what is ? And why nothing to work …  
Also i’m don’t find tcp ip library and documentation in this OpenAT version.
