指定启动文件~/.gdbinit下面的方法任选其一。 1、调用GDB时指定启动文件。
# gdb -command~/.gdbinit a.out 2、运行GDB后指定启动文件。 2.1、“source /.gdbinit”临时导入/.gdbinit文件。 2.2、添加“add-auto-load-safe-path /.gdbinit”到/.gdbinit文件中使该文件可以被加载; 2.3、添加“set auto-load safe-path ./”到./.gdbinit文件中相当于禁用了安全路径的保护

# STL GDB evaluators/views/utilities - 1.03
#
# The new GDB commands:
# are entirely non instrumental
# do not depend on any inline(s) - e.g. size(), [], etc
# are extremely tolerant to debugger settings
#
# This file should be included in .gdbinit as following:
# source stl-views.gdb or just paste it into your .gdbinit file
#
# The following STL containers are currently supported:
#
# std::vectorT -- via pvector command
# std::listT -- via plist or plist_member command
# std::mapT,T -- via pmap or pmap_member command
# std::multimapT,T -- via pmap or pmap_member command
# std::setT -- via pset command
# std::multisetT -- via pset command
# std::dequeT -- via pdequeue command
# std::stackT -- via pstack command
# std::queueT -- via pqueue command
# std::priority_queueT -- via ppqueue command
# std::bitsetn -- via pbitset command
# std::string -- via pstring command
# std::widestring -- via pwstring command
#
# The end of this file contains (optional) C beautifiers
# Make sure your debugger supports $argc
