CCS: unresolved symbol _GPIOPinWrite, first referenced in ./ST7735.obj

Tool/software: Code Composer Studio

Hello,

I'm trying to compile the example for the ADAFruit ST7735 screen with the TM4C123GXL eval board.

I took it from here:

"github.com/.../examples"

I am getting a linker error of :

unresolved symbol _GPIOPinWrite, first referenced in ./ST7735.obj

I understood that this function should be defined in the driverlib library.

I tried linking the library in the linker options but it didn't help.

Note that I didn't find the tivaware for the TM4C, so I'm using the lib for CM4F:

Lib name: "driverlib-cm4f.lib"

Lib directory: c:\StellarisWare\driverlib\rvmdk-cm4f\

I used it before and it worked, so I'm a bit confused here.

I would appreciate some help with that issue.

Thanks,

Nadav
