I've managed to get binutils, gcc, libc and gdb compiled for Mac OS using macports. In parallel I tried the original win32 insttalation on Vista using parallels set-up. Both set-up show the same behaviour, that no bss could be found. I read the messages in the board, added the variables and saw, that a '.data' appeared. But the msp430-gdb keeps saying, that no bss is avaible. Some information from the files: $ msp430-objdump -h main main: file format elf32-msp430 Sections: Idx Name Size VMA LMA File off Algn 0 .text 00000054 0000fc00 0000fc00 00000094 2**1 CONTENTS, ALLOC, LOAD, READONLY, CODE 1 .data 00000002 00000200 0000fc54 000000e8 2**1 CONTENTS, ALLOC, LOAD, DATA 2 .vectors 00000020 0000ffe0 0000ffe0 000000ea 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 3 .stab 000000f0 00000000 00000000 0000010c 2**2 CONTENTS, READONLY, DEBUGGING 4 .stabstr 0000001e 00000000 00000000 000001fc 2**0 CONTENTS, READONLY, DEBUGGING <----------> GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.
