'SoftwareSerial' does not name a type

Hi, I’m having a minor problem with my code that I’m trying to sort out. I have this code. I’m currently trying to develop a gps tracker and I’m involving a LCD display, LM35. ESP8266 and an Arduino Uno. Everything has been working fine using this code until I put in void printGpsGsm(), and then I get the following errors at the bottom

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

I’m just wondering could someone solve this issue for me? Thank you

Maybe it works if you get rid of Serial in SoftwareSerial Serial serial_connection

And you seem to be missing the include.

Sorry that was a mistake putting in Serial in there, it shouldn't have been in there but I still have the same issues when I take it out also

And my second point?

And my second point?

The #include is it? I’m not sure which #include you are talking about, I’m sorry

#include <SoftwareSerial.h>
