今天为调试一段代码,使用gcc将程序用-g选项重新编译。但是使用gdb进行debug时,仍然出现“no debug symbols found”的错误。仔细检查了一下Makefile,原来后面定义的连接选项中指定了-s。gcc的文档中说明如下: -sRemove all symbol table and relocation information from the executable. 去掉-s后,可以用gdb进行调试了...
简单总结一下-g选项与-rdynamic选项的差别: 1,-g选项新添加的是调试信息(一系列.debug_xxx段),被相关调试工具,比如gdb使用,可以被strip掉。 2,-rdynamic选项新添加的是动态连接符号信息,用于动态连接功能,比如dlopen()系列函数、backtrace()系列函数使用,不能被strip掉,即强制strip将导致程序无法执行: [root@www...
