Problem compiling 3pi-demo-program

I am unable to get the 3pi-demo-program to compile. I think it may have something to do with the avr/pgmspace.h library.

When I try to compile I get the error below. It looks like the prog_char type is not being recognized correctly. Any ideas on how to fix this?

Hello, alzabo.

Thank you for letting us know about this problem. In recent versions of avr-libc, prog_char and similar typedefs have been deprecated. The relevant documentation is here:

nongnu.org/avr-libc/user-man … space.html

I think you might be able to fix the problem by writing the following line at the very top of the program:

#define __PROG_TYPES_COMPAT__

Let me know if that works. I think it will not work for the latest version of avr-gcc, but it might work for you.

The next release of the Pololu AVR C/C++ Library should be fixed to not use those types.

The compiler gives warnings for use of deprecated typedef; however, the code compiles and everything appears to function normally. Thanks!
