Starting a project

Hi
Iam trying to start a new project based on STM32F105VC ,
I opened Uv4 then new project,
I write juts very small code for test , it has two files main.c and init.c
when i compile them I get the following error ,
t1.axf: Error: L6218E: Undefined symbol GPIO_Init (referred from intiports.o).
t1.axf: Error: L6218E: Undefined symbol GPIO_StructInit (referred from intiports.o).
t1.axf: Error: L6218E: Undefined symbol RCC_APB2PeriphClockCmd (referred from intiports.o).
couid you help to solve this issue

thank you
