问 我用的是cc2000 ，cmd 文件如下：

MEMORY
{
  PAGE 0:
        VECS            origin = 0000h,         length = 0040h
        FLASH:          origin = 100h,         length = 7F00h
        SARAM_P:        origin = 8100h,         length = 1000h

  PAGE 1:
        B2:             origin = 0060h,         length = 020h
        B0:             origin = 200h,         length = 100h
        B1:             origin = 300h,         length = 100h
        SARAM_D:        origin = 0C00h,         length = 400h
}

SECTIONS
{
        vectors:        > VECS          PAGE 0
        .text:          > FLASH         PAGE 0
        .data:          > FLASH         PAGE 0
        .bss:           > B2            PAGE 1
        stack:          > B1            PAGE 1
        buffer:         > SARAM_D       PAGE 1
}
主函数如下：
#include "inc.h"


int a;
void    asdfsdf(void)
{
    int    i;
    for(i=0;i<10000;i++)
        {
            a++;
            
        }

}    

void    main(void)
{
    int i=0;
    a=1;
    a=SSS;
    for(i=0;i<10000;i++)
        {
            asdfsdf();
            a+=i;
            a++;    
        }
}
编译后出现如下错误：
>> CANnot allocate .bss in B2 (page 1)
>> errors in input - wen2.out not built
Build Complete,
  2 Errors, 0 Warnings.


请高手指教一二！！！不胜感激！！

答 1: re不要把。bss放在B2看看
还有project－>options中路径没有设定好 答 2: .bss变量分配不成功.bss:           > B2            PAGE 1
把B2 改为SARAM_D较为合适
答 3: 改了，出现新错误！！！>> CAN't allocate .stack, size 00000400 (page 1)
>> errors in input - wen2.out not built
Build Complete,
  2 Errors, 0 Warnings. 答 4: 一般是存储器空间不够出上面的错误. 答 5: 在cmd 文件中加条语句，好使！！！-STACK 40 /*后加的*/

虽然好使，但是，不知为什么！ 答 6: 制定stack区的大小，具体可见help->stack optionThe C/C++ compiler uses an uninitialized section, .stack, to allocate space for the run-time stack. You CAN set the size of this section at link time with the -stack option. Specify the size as a constant immediately after the option. The example below creates a stack that is 4K words in size:
lnk2000 -stack 0x1000  /* defines a 4K stack (.stack section) */
If you specify a different stack size in an input section, the input section stack size is ignored. Any symbols defined in the input section remain valid; only the stack size is different.

When the linker defines the .stack section, it also defines a global symbol, __STACK_SIZE, and assigns it a value equal to the size of the section. The default software stack size is 1K words.
