 How to add library into the project?

Hello all,

I've a workspace which contain a library project and blinky project. *when a library project compiled successfully, it's created a lib??.a not lib??.lib

Well, then I would like to add library(.a, i assume this is a keil's library) into blinky project. But it's occured errors like

"..\halfx\build\libhalfx.a(1): error: junk at end of line, first unrecognized character is '!'"

Could anybody help me?

Thank you
