I went through the replies as pointed out but none solve the issue.
I tried to close Arduino IDE 1.9.0 and start all over again but get the same compilation error.
Any comprehensive solution will be appreciated.
I can compile examples in IDE and they all run OK, so I do not think I have any hardware/software issue with IDE.
Thanks.
I am trying to setup Building a WiFi Gateway using ESP8266 and followed the instructions carefully. When I tried to compile using Arduino IDE 1.9.0, I get the following error: exit status 1
Error compiling for board NodeMCU 1.0 (ESP-12E Module ).
Please help what is missing or what I am doing wrong?

Good project. Can you please share more details with schematics and the board layout? I would like to build this one.
Thanks.
