arduino compile errors everytime

Can someone please help me. Everytime I try to compile anything for the esp12e board except for the arduino examples, it gives tons of error codes. I know I am missing something but I just can't figure out what it is. I tried to run the pir sample code from this website. Thanks for any help
Arduino: 1.6.7 (Windows 7), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Serial, 115200, 4M (3M SPIFFS)"

Build options changed, rebuilding all

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

I have that problem as well.

I have to cut and paste all the voids, and put them below the setup, and loop voids.

When you find out......

What USB drivers are you using?
