移植blob到44B0时,编译出错!!

lvshishi

楼上的兄弟可不可以说清楚一点，要安装哪些工具？

既然是做移植，当然就需要安装arm的交叉编译工具链了。建议你好好看一下blob软件包中的README和INSTALL文件。

lvshishi

我装过arm-elf-gcc-2.95.3-2.i386.rpm

那你最好确定一下你在编译的时候调用的是这个编译器。

谢谢楼上兄弟的指点,真的是编译器的设置有问题.
不过现在又有了新问题:

编译提示有很多东东没有定义,我上网查了一下,这些数据类型应该定义在include/asm/setup.h下面的,可是我发现我机器里的这个文件里面什么都没有定义,只有下面几行:
#ifndef _i386_SETUP_H
#define _i386_SETUP_H


#endif /* _i386_SETUP_H */
我想请教一下,里面的内容是不是要自己定义?如果是的话,该怎么定义?如果哪位兄弟有定义好的setup.h,还望能发给我一份,谢谢了!!

lvshishi

上面的问题我已解决,将原来的头文件#include <asm/setup.c>改为 #include <asm-arm/setup.c>就行了.
现在又有了新问题:
__main.o(.text+0xbc): undefined reference to `atexit'
__main.o(.text+0xbc): relocation truncated to fit: R_ARM_PC24 atexit
collect2: ld returned 1 exit status

还请各位达人帮帮忙啊,小弟已经折腾了两天了,还没有编译通过.

atexit()是glibc的库函数。
你最好确定一下交叉编译环境是否配置成功了，特别是glibc库。

你好像没有用交叉编译的gcc阿？ 那怎么能有-mtune的选项呢？

下载一个arm-linux 的交叉编译工具连，
1) ELDK的toolchain, 不必用很新的版本，用3.1就够用了。
2) 用crosstools自己编译一套：http://kegel.com/crosstool
等等。

然后按照下面的方法:

# CC=arm-linux-gcc OBJCOPY=arm-linux-gcc ./configure --host=i686 --target=arm --your_options_here.
# make

谢谢楼上的兄弟，编译通过了，不过烧到flash里之后，没反应啊！
不知道有没有可以在linux下调试和烧写blob的工具啊？还请各位达人指导一下linux下调试blob的方法，谢谢！
