Hello,

after almost 12 years I've got a similar problem!!

I am using Quartus 14.1sp1 and a NIOS II gen2.

I get the following error while trying to compile my application (working in Quartus 7.1, NIOS II classic):

obj/default/lpc_lib.o: in function `lsp_to_freq':

lpc_lib.c:649: warning: unable to reach (null) (at 0x800476b8) from the global pointer (at 0x8003f5d8) because the offset (32992) is out of the allowed range, -32678 to 32767.

collect2: error: ld returned 1 exit status

make: *** [rio_audio_codec.elf] error 1

I tried to define all the extern variables with the "[]" at the end (as suggested above), but the problem is still present.

I tried also to use the -G0 flag in the application, but the problem was not solved.

Should I also specify the same flag for the BSP ? If so, how?

Anyway I'd like to solve the problem definetely (without using the -G0), also because I need to reach some performance.

Any hint is more than appreciated,

thanks on advance
