Error when compiling, do you need a C environment?

[Spoiledpay]

I'm trying to compile and I noticed that we can compile in a few ways. But this could be easier.
Without the visual studio tools environment installed, the compilation does not occur, generating failures and strange warnings, would this be correct? Do you need the Visual studio environment?

What environment do you need to cleanly compile the examples? which path should be inserted?

I tried to compile the example HelloWord.

Using the visual developer prompt works.

Trying to compile outside the root helloword path generates a permissions error. Would this be correct or do we need adjustments to be able to compile in any directory?

The compiler is in the path and helloworld is in another directory and the code was not compiled.

Hello, Can you help answer some questions about PATH, Environment and compilation outside the CX compiler directory?
