Hello,in order to become familiar with the STM32F10X I first modified the Blinky program.But I have a problem.When I Build Target,there are errors as follows:

Target not created
What did I forget, do wrong ?
Thnks for any help,
mouxiang
Those symbols all look like names from the STM32 Firmware Library - so it looks like you forgot to link the STM32 Firmware Library
Thanks. but I don't know how to link the STM32 Firmware Library. "Options for target ..."->"Linker" Is that right?
Hi xiang mou,
Do you have the below file?
C:\Keil\ARM\RV31\LIB\ST\STM32F10xR.LIB
Try to find it on your KEIL PC, and add it to your project, just like you add a new source file.
Thanks very much ,John. I find STM32F10xR.LIB and add it to my project,and this time there's no error!
