BTW, I have realized that I was compiling for the default target, not PIC16. Now, I'm getting some linker errors. I'm attaching the sources, you can test it just with # make
I have commented out "puts" and "#include <assert.h>" and two assertions. But I still get the following: [EMAIL PROTECTED]:~/Desktop/chess/firstchess/pic16$ make sdcc firstchess.c -mpic16 -o firstChess message: using default linker script "/usr/share/gputils/lkr/18f452.lkr" warning: relocation of section "udata_firstchess_7" failed, relocating to a shared memory location error: linker script has no definition that matches the type of section "udata_firstchess_7" make: *** [all] Error 1 Any idea??
