Re: [avr-gcc-list] section .vectors [0000000e -> 00000027] overlaps section .data ...

Jan,

I just tried this with the previous avrfreaks win32 release, 3.0.2 and it
works fine. Since you are using the 8515, why not use that version of
avrgcc? I used the gcctest1 sample and stuck your code in there. Output from
compiler:

C:\avrgcc\gcctest\gcctest1>make
avr-gcc -c -g  -Os -Wall -Wstrict-prototypes -Wa,-ahlms=gcctest1.lst -mmcu=a
t90s
8515 -I. gcctest1.c -o gcctest1.o
avr-gcc  gcctest1.o   -Wl,-Map=gcctest1.map,--cref -mmcu=at90s8515 -o

Errors: none


I haven't tried with 3.2 yet.

PS in your case it compliles fine but it doesn't link very well :-)
