Dear all,
I am trying to build cross compiler for xc16x. I built successfully
binutils 2.18; gcc 4.0 and newlib 1.18. Everything is fine when
compiling a simple C file without any library call. It is also fine
when making a simple call to printf like printf("Hello world").
However, i got error message from linker when call printf("i=%i",i);
The error message is as follows
/home/guest/xc16x/lib/gcc/xc16x-elf/lib/xc16xl/libc.a(lib_a-sbrkr.o):
In function _sbrk_r:
/home/guest/newlib-1.18.0/newlib/libc/reent/sbrkr.c:60: undefined
reference to __sbrk
/home/guest/fromKpit/newlib-1.18.0/newlib/libc/reent/sbrkr.c:60:
undefined reference to __sbrk
....
collect2: ld returned 1 exit status
make: *** [bubble.out] Error 1
Is there any idea how to solve the problem? I highly appreciate any help.
Best regards,
Phung
