python - Fedora 19 Pyclewn 找不到GDB版本

Question

如何让 pyclewn 获得我的 gdb 版本？

[mehoggan@localhost emulator]$ pyclewn

Answer 1

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

从第 328 行开始:

            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:]))

问题在于它如何处理版本字符串中的第一个 '(' 字符:

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

它只使用了这个输出的第一行:

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

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