如何获得pyclewn以获得我的gdb版本？

Answer 1

我在我的Red Hat盒子上遇到了同样的问题。我通过转到引用的文件和行号：/usr/lib64/python2.7/site-packages/clewn/gdb.py:340并进行以下修复来修复它：

从328线开始：

            version = ''.join(takewhile(lambda x: x.isdigit() or x == '.',
            version[1]))

并将其更改为：

            version = ''.join(takewhile(lambda x: x.isdigit() or x == '.',
            version[1][1:]))

问题是它如何处理版本字符串中的第一个"("字符：

[root@localhost ~ 03:52 PM] $ gdb -v

它只使用这个输出的第一行：

GNU gdb (GDB) Red Hat Enterprise Linux (7.0.1-42.el5)

通过在version[1]之后添加[1:]，我告诉脚本无条件跳过第一个字符，这在我的机器上是需要发生的。这可能不是一个长期的解决方案，但它让我的pyclewn工作起来了=）

Answer 2

据报道，的Suse也存在类似问题

http://sourceforge.net/p/pyclewn/bugs/119/

这个问题现在在pyclewn开发分支中得到了解决还修复了Fedora（7.6-32.fc19）的问题。所以这两个问题将在下一个pyclewn版本1.11中修复。

Fedora和Suse gdb发行版都有一个gdb头不符合GNU编码标准。参考已经出现的错误发布给Fedora漏洞跟踪器，地址：
