本文介绍了一个使用GNU gdb进行程序调试时遇到的问题：由于编译时未加入-g选项导致无法加载符号表，进而无法查看源代码及变量等调试信息。文章提供了问题的解决办法。
gdb 调试程序时出现下面信息：
GNU gdb Red Hat Linux (5.3post-0.20021129.18rh)

This GDB was configured as "i386-redhat-linux-gnu"...(no debugging symbols found)...
然后（gdb）l 出现
No symbol table is loaded. Use the "file" command.
问题出现的原因：
编译时未加调试选项（(g)cc/g++ -g ... ）
