Hi,

I'm relatively new to gcc and WinAVR. I'm still working out how everything works. I'm trying to get the HID USB Keyboard code to compile. However, whenever I try to make it, I get errors sying that there is no target defined. When I looked the makefile template that comes with WINAVR, it differs from the one that Christopher wrote for the USB. When I try to compile with an editted makefile template, I can compile, but I still get errors.

Can anyone explain how to get Chris's makefile working and how to get everything working in general?

Thank you!

Are you referring to the HIDKeys example? The makefile in that example DOES have a default target named "all". If it is not found, something is seriously broken in your development environment.

Can you post the exact error messages?

Yes, the HIDKeys example.

Okay, I got it to recognize the make file. I saw the default target as all, so I'm nto really sure what went wrong. I restarted programmer's notepad and then it worked. It just gives the following error now.

avr-gcc -Wall -Os -Iusbdrv -I. -mmcu=atmega8 -c usbdrv/usbdrv.c -o usbdrv/usbdrv.o
avr-gcc -Wall -Os -Iusbdrv -I. -mmcu=atmega8 -x assembler-with-cpp -c usbdrv/usbdrvasm.S -o usbdrv/usbdrvasm.o

That's an error in the checksize script, probably because you don't have awk or another Unix tool installed. You can safely ignore this error or remove the checksize call altogether. It's only a check to see how much memory is used by the code.

Try changing "awk" in the checksize script to "gawk". Worked for me.

Thank you!

A quick question also about the Makefile. To program using WINAVR, I just need to change the uisp and the serial lines, right? I hit the program make in the WINAVR and it said target not defined.

I just create on c:/ path the file "documents" and works for me
