Convert to C++ project


I am unable to get any C++ code to compile, unless I use the C++ example in the Digi ESP. Here is what I am doing. Net OS 7.3:

  1. Create new “NET +OS PROJECT”. All settings default, I check off “include C++” in the options.
  2. Default project is created and loads correctly.
  3. I try to compile and C++ files, or include a c++ library. For example if I add "include to root.c.
  4. will not compile. (error: iostream: No such file or directory)

Any ideas? I don’t see any differences between the sample C++ projace and a new NET +OS PROJECT".

Thanks in advance for any help!
