Hello,
I am facing compilation error while working with GPS module.
First of all I am working with additional software serial port to test my GPS module.
I am facing the below error:
======================
Verifying...
C:\Users\USER\AppData\Local\Temp\ccG2O1Lp.ltrans1.ltrans.o: In function `__static_initialization_and_destruction_0':
E:\B4R\PROGRA~1\SOFTWA~1\Objects\bin\sketch/b4r_main.cpp:16: undefined reference to `DFRobot_SIM808: DFRobot_SIM808(unsigned char, unsigned char, unsigned long)'
collect2.exe: error: ld returned 1 exit status
exit status 1
=======================
Below is my code:
I know that this is a linker issue and the linker cannot find the desired function. But the function "DFRobot_SIM808: DFRobot_SIM808" is already there.
Anyone please suggest.
Thanks-
Pokhraj Das
