gdb 7.11

由於CentOS自帶的GDB版本有點低，因此下載了最新的gdb 7.11編譯之後，調試過程當中提示如下錯誤。

Python Exception <type 'exceptions.NameError'> Installation error: gdb.execute_unwinders function is missing:

修改方式：

將源碼目錄下的python模塊拷貝到指定目錄便可。

Python Exception <type 'exceptions.ImportError'> No module named gdb:
gdb: warning:
Could not load the Python gdb module from `/usr/local/share/gdb/python'.
Limited Python support is available from the _gdb module.
Suggest passing --data-directory=/path/to/gdb/data-directory.

能夠看出，應該放在/usr/local/share/gdb/python

gdb源碼目錄爲

/home/dennis/DennisCode/gdb-7.11/gdb/python/lib/gdb

徹底拷貝便可
