"GRBL_MPG_DRO_BoosterPack" project compilation error

[大尾巴狼YO~YO~]

I download the project from this link。https://github.com/terjeio/GRBL_MPG_DRO_BoosterPack.git

I use "Code Composer Studio 12.0.0" to open the GRBL_MPG_DRO_BoosterPack-master\Firmware\TM4C123 project。I compile and the compiler tells me there are 16 errors。
"../src/canvas/sdcard.c", line 177: error #256: type name is not allowed
"../src/canvas/sdcard.c", line 177: error #66: expected a ";"
"../src/canvas/sdcard.c", line 177: error #20: identifier "i" is undefined
3 errors detected in the compilation of "../src/canvas/sdcard.c".
gmake: *** [src/canvas/sdcard.obj] Error 1

I made a modification to the code：

if(!canvasSDCard)
{
canvasSDCard = UILibCanvasCreate(0, 0, 320, 240, handlerCanvas);
listPrograms = UILibListCreate((Widget *)canvasSDCard, 10, 40, 300, LISTELEMENTS, handlerProgramList);
{
uint_fast8_t i;
for(i = 0; i < LISTELEMENTS; i++)
UILibListCreateElement(listPrograms, i, "", handlerSelectList);
}
}

error disappears。

After I solved all the errors of this type, a new error appeared

I made a modification to the code：
__attribute__((weak)) void serial_RxCancel (void){};

all errors disappear

Retested with Tiva C after RP2040 (Pi Pico) changes, seems ok now.
