已解决 //求助：skyeye无法正确load elf文件

winarm编译生成code_road.elf，模拟环境是 cygwin + skyeye1.2.6， 在pc上运行正常。

今晚在另一台pc上安装skyeye，却运行出错，从错误信息看是skyeye没有找到属性为SEC_LOAD的section。

为什么会这样，是编译出了问题吗？

make的打印太大，超过了限制，只能放在附件里。

这个问题，在网上找不到类似的例子，只能到这里求助，请大家不吝赐教！

cygwin中的gcc版本为3.4.4。

以为是bfd库与winarm产生的elf存在兼容问题，使用make NO_BFD=1编译，结果如前。

wt133664

在utils\main\skyeye.c中，有两个tea_load_exec()，前面一个不使用bfd lib来load elf，而后面用bfd lib来load elf。

通过在这两个函数中增加打印，发现make NO_BFD=1没有起作用，skyeye始终用bfd lib来load elf。

在config.h中手工将define HAVE_BFD_H 1与#define HAVE_LIBBFD 1注释掉，再编译，则问题解决。

wt133664

为什么用winarm编译出来的同一个elf文件，在以前的skyeye-1.2.6中运行正常，而在新安装的skyeye-1.2.6中存在bfd lib无法正确加载的问题呢？
