我想使用gdb
调试python
脚本。启动gdb
后,它输出:
[root@localhost scripts]# gdb python

Missing separate debuginfos, use: debuginfo-install python-2.7.5-16.el7.x86_64
根据它的提示,我执行debuginfo-install python-2.7.5-16.el7.x86_64
命令,输出如下:
[root@localhost scripts]# debuginfo-install python-2.7.5-16.el7.x86_64

如何安装python调试信息?
关于如何在各种操作系统上安装python debuginfo,有一些说明here
具体来说:
我相信调试信息是为了调试Python解释器本身,而不是Python脚本。据我所知,gdb并不了解Python脚本。如果启动
gdb python
,则要求gdb调试python解释器。要调试Python脚本,可以使用pdb(而不是gdb),它的命令有一些相似之处。。。
编辑:所以问题是如何安装Python的调试信息。确定要调试Python本身吗?
这里有一些想法:RHEL iso可能不是正确的-devel信息源。我不认为原始的iso会有你需要的信息。
我在几个地方找到了原始python包的-debuginfo包,但是有一个警告(例如http://rpm.pbone.net/index.php3/stat/4/idpl/26126276/dir/redhat_7.x/com/python-debuginfo-2.7.5-16.el7.x86_64.rpm.html)说:
是http://buildlogs.centos.org/c7.00.04/python/20140617165351/2.7.5-16.el7.x86_64/上调试信息的一个版本。我已经很多年没有使用过百胜了,但是我相信你可以手动下载那个包,然后在下载的包上运行百胜来安装它。根据最初问题中的消息,您还必须安装glibc和python libs的
debuginfo
(或者可能先安装)。类似于:yum --nogpgcheck localinstall packagename.arch.rpm
