殷切期盼问题解决中...

您尝试打上这个patch看看。

tenthplanet 发表于 2011-8-10 12:54:49

谢谢您的指导，不过看起来好像
还是不行啊，调试错误如下：（跟以前提示的错误一样）

这是个棘手的问题，非常感谢你们！

xq2537 发表于 2011-8-15 10:57:22

你把你的二进制的测试用例和skyeye.conf发过来，好吗？调一下，呵呵

xq2537 发表于 2011-8-15 11:10:09

您如果急于解决这个问题，权宜之计，您可以在utils/debugger/gdbserver.c中添加如下5行：

13 diff --git a/utils/debugger/gdbserver.c b/utils/debugger/gdbserver.c
14 index 0f9f541..2a3d973 100644

22 +                {

28               if ((get_trace_status() == TRACE_FOCUSING) && (is_in_ro_region(mem_addr,len) == 0))

（同样期待您的测试用例和skyeye.conf,我们想调一下，找出真正的bug所在）

tenthplanet 发表于 2011-8-15 13:41:24

例子和skyeye.conf已经附上，谢谢您的帮助，殷切期待问题解决！

附件下载不了阿，这是我的邮箱：

xq2537 发表于 2011-8-16 20:21:54

您发的二进制文件和skyeye.conf下不下来，您能不能发到我的邮箱里去？
[email protected]

tenthplanet 发表于 2011-8-17 15:05:01

不好意思让您久等，这2天我人在外面。
明天我一到家就给您发，真是麻烦您了。

tenthplanet 发表于 2011-8-18 08:10:57

我已经发给您了，谢谢您的热情解答和帮助。

我在ubuntu1004上测了一下你的测试用例，没有重现你的错误：

skyeye官方只支持ubuntu和windows，您要不换一下ubuntu吧？
