python异常<type'exception.ImportError'>没有名为gdb的模块:

Question

我刚刚gdb 7.8在运行linux的服务器机器上从我的主目录中的源代码编译.我以前一直在使用gdb 7.6,除了gdb自身的稳定性问题(升级的原因)一切正常.

自升级以来gdb,当我运行时,cgdb 0.6.7我立即得到以下消息:

Python Exception <type 'exceptions.ImportError'> No module named gdb:

warning:
Could not load the Python gdb module from `/home/username/bin/gdb//python'.
Limited Python support is available from the _gdb module.
Suggest passing --data-directory=/path/to/gdb/data-directory.

当我建造时gdb,我使用了./configure --with-python.

当我运行cgdb并且我的程序达到段错误时,我输入backtrace并获得以下消息:

Python例外没有名为gdb.frames的模块:

所以看起来我实际上无法使用gdb/ cgdb没有python支持.我该怎么做才能解决这个问题？

FWIW; 我不用python,我经常写c++.

Answer 1

您应该指定" --data-directory" 的值.例如,如果gdb从构建目录加载,则命令应为:

./gdb -data-directory ./data-directory

然后gdb可以知道在哪里找到python模块.

你可以参考这个讨论.

Answer 2

root@labs:~/gdb-8.1# gdb --version
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.
....

尝试将 python lib cp 到 --data-directory= /path/to/gdb/data-directory。我的数据目录是/usr/local/share/gdb/python，

# mkdir -p /usr/local/share/gdb/python/gdb
# cp -rf ~/gdb-8.1/gdb/python/lib/gdb/* /usr/local/share/gdb/python/gdb/
