安装GDB后运行汇编代码脚本出现版权信息，是否安装有误？

运行.asm文件时曾提示gdb not found，于是通过终端执行sudo apt-get install gdb安装了GDB。但现在运行代码时会弹出GDB的完整版权许可信息，请问是否安装错误？

运行时输出如下：

rm: cannot remove '*.o': No such file or directory
rm: cannot remove '*.lis': No such file or directory
rm: cannot remove '*.out': No such file or directory

没有安装错误，GDB的版权信息是正常启动提示，不属于安装问题。

原因分析 #

1. 你的运行脚本在“Run the Float Program”步骤中，调用了GDB来启动程序，而非直接运行编译后的可执行文件。比如脚本里用了gdb ./xxx.out这类命令，而非./xxx.out，所以GDB启动时会默认显示版权信息。
2. 开头的rm错误只是脚本尝试清理旧的目标文件、列表文件和可执行文件但未找到，属于无关的警告，不影响程序编译和运行。

解决办法 #

• 直接运行程序：修改脚本中的启动命令，把调用GDB的语句改成直接运行编译生成的.out文件。例如将gdb float_program.out改为./float_program.out，这样就不会触发GDB启动。
• 保留GDB但关闭版权信息：如果确实需要用GDB调试，可在启动命令中添加-q（安静模式）参数，比如gdb -q ./float_program.out，这样GDB会跳过版权和欢迎信息，直接进入调试界面。
