Other Parts Discussed in Thread: EK-LM3S3748
I just installed CCS V4.1.0.02003 . Following the quick statrt pdf on using CCS 4.1 with Stellarisware, I imported the StellarisWare CCS projects (release 5570) for driverlib, grlib and usblib. I then imported Hello and usb_dev_bulk projects for the ek-lm3s3748. I built the driverlib and grlib libraries with no problems. However, I can't build the usblib, Hello or usb_dev_bulk projects. For the usblib and usb_dev_bulk projects I get the following error for most of the source code files:
"C:/StellarisWare/usblib/ccs/../../usblib/usblib.h", line 82: fatal error: #error Unrecognized COMPILER!..."
The error comes from a #if statement looking for defines for valid compilers (e.g., codered, gcc, etc.). It seems like there should be a macro for ccs that will allow the library to compile. I've searched quite a bit but haven't been able to find anything.
For the Hello project, I thought I would not have this problem since it does not rely on the usblib library. However, when I compile Hello, I get the following linker error
undefined first

NumLeadingZeros
C:/StellarisWare/boards/ek-lm3s3748/hello/ccs/../../../../grlib/ccs/Debug/grlib.lib<string.obj>
SysCtlDelay
./drivers/formike128x128x16.obj
I traced the problem back to macros and it turns out to be a similar problem to the usblib compile error. That is, the NumLeadingZeros implementation depends on the compiler define (e.g., codered, gcc, etc.).
I'm a bit perplexed with these problems since I'm using CCS projects. I'm probably missing something simple, but can't figure it out. I'd appreciate some help with this problem.
Thanks in advance!
