Exit status 1 Error

I have an issue with my code. When I compile my code, I receive a "Exit status 1" error. May someone please tell me where I'm going wrong. My code is...

#include <SoftwareSerial.h>

Nothing else?
Just that?

I just resolved that error. I am currently stuck with this error code now.

I used this website (How to connect NodeMCU V2 to ThingsBoard? | ThingsBoard Community Edition) to generate this code and i don't understand why I received this error.

#define THINGSBOARD_ENABLE_DYNAMIC 1

This constant is already defined as a 0 in the Thingsboard header file. The compiler complains when you try to give something two different definitions.
If you look in the folder where that library is, you'll find a SRC subfolder. Inside that is a file configuation.h, and that constant is defined in there on line 52

constexpt unit32_t SERIAL_DEBUG_BAUD 115200U;

I believe you are missing an equal sign between the variable name and the value.

subscribed = false;

You are using this variable, but you have not told the compiler what type of variable it is. You always need to define a variable before you can use it.

constexpt unit16_t THINGSBOArD_PORT=1883U;

There appears to be a typo in the variable name where you defined it. C is case sensitive, so THINGSBOARD_PORT, ThingsBoard_Port and THINGSBOArD_PORT are three different variable names to the compiler.

For the last error, you have a mismatched number of { and } braces in the loop function.
When writing your code, it helps to indent the code by at least four spaces every time you open a {, and reduce the indent level every time you use a } to close a block of code.
