【中文标题】GDB - 未找到调试符号 -【英文标题】：GDB - No Debugging Symbols Found - 【发布时间】：2016-09-18 17:29:30 【问题描述】：

所以我托管了一个 8.6 的 OpenTibia-Server。有时服务器冻结，我不知道是什么原因导致它冻结，所以我请我的朋友帮助我，他告诉我用 gdb 选项编译控制台。我做到了。但是当我在控制台冻结后将它附加到 GDB 时，它说没有找到调试符号。我也添加了选项 -g 和 -s（第 6 行），但它不起作用。

这是我的 Makefile.am：

noinst_PROGRAMS = theforgottenserver

CXXFLAGS = -pipe -std=gnu++11
AM_CXXFLAGS = $(XML_CPPFLAGS) $(OTSERV_FLAGS) $(LUA_CFLAGS) $(DEBUG_FLAGS)\
$(mysql_FLAGS) $(SQLITE_FLAGS) $(PGSQL_FLAGS) $(PROFILER_FLAGS)\
$(OPTIONAL_FLAGS) -D_THREAD_SAFE -D_REENTRANT -Wall -Wextra -Wno-strict-aliasing -llua5.1 -I/usr/include/lua5.1 -g -s

theforgottenserver_LDADD = $(LUA_LIBS)

if USE_MYSQL
MAYBE_MYSQL = databasemysql.cpp databasemysql.h
endif
if USE_SQLITE
MAYBE_SQLITE = databasesqlite.cpp databasesqlite.h
endif
if USE_PGSQL
MAYBE_PGSQL = databasepgsql.cpp databasepgsql.h
endif
if LOGIN_SERVER
MAYBE_LOGIN = gameservers.cpp gameservers.h
endif
if OT_ADMIN
MAYBE_OTADMIN = admin.cpp admin.h
endif

当我附加GDB 并运行bt 时，这是我在终端上得到的

【问题讨论】：

您的屏幕转储显示您将 gdb 附加到“屏幕”进程，而不是您的程序。您将其附加到错误的进程。我该怎么办？将 gdb 附加到正确的进程。清理构建，然后再次构建，查看编译命令的输出，看看是否使用了您期望的标志。 【参考方案1】：
