gdb无法单步调试 使用gdb调试单步程序时如果打印提示“single stepping until exit from function xxx,which has no line number information”,可能的原因有两个: 1 编译源文件时没有加-g选项; 2 gcc与gdb版本不兼容,通常是由于手工对gcc程序进行了升级,导致现有gdb程序版本过旧,比如gcc升级到4.8版本,gdb仍为旧的...

Single stepping until exitfromfunction__libc_start_main,which has no line number information.Program exited normally.(gdb) 结尾的内容显示,还有另一个库函数(__libc_start_main()在调用main()函数!但因为它不是使用调试信息编译的,因此我们看不到源代码,但我们仍然可以通过next单步执行,并且程序会正常退出。
