Question on Porting NETMF

I read the Beginners Guide to Porting NETMF, and tried to follow the instruction on the book on installing the 8.5.GNU GCC Compiler.

MSBUILD.EXE /t:build /p:flavor=release;memory=flash

But also got an error message saying the

What have I done wrong?

Did you run the bat file that sets the environment ? This will set the path to msbuild. I can look it up for you later - if needed.

setenv_gcc.cmd

yes, I did so! ???

The build uses c++ compiler. Do you have c++ installed?

That solved my problem! ;D

I thought I had C++ installed on this computer, but it wasn’t!

Thanks.
