python - Fedora 19 Pyclewn Cant查找GDB版本

如何获取pyclewn以获取我的gdb版本？

[mehoggan@localhost emulator]$ pyclewn
gdb  CRITICAL response to "show version":

最佳答案

我在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并进行以下修复来解决此问题：

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

它仅使用此输出的第一行：

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

通过在[1:]之后添加version[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解决方案，但它使我的pyclewn正常工作=）
