symbol _GPIO_Init not defined (Debug\main.o )

[MQi.1]

I tried the example code in this document - dm00405517-getting-started-with-the-stm8s001j3-microcontroller-stmicroelectronics.pdf, the code was:

I could compile it in STVD:

while, I couldn't build it:

exit code=1.

does anyone know the reason?

[MQi.1]

I found the reason: I haven't included the "stm8s_gpio.c".
