gcc -ggdb和gcc -g有什么区别? [英] What is the difference between gcc -ggdb and gcc -g
问题描述
当我使用gcc编译C程序
时,我通常使用 -g
来获取一些调试信息到elf文件
中,以便gdb可以帮助我,如果需要的话。
但是,我注意到一些程序使用 -ggdb
,因为它应该使
debug info更加gdb友好。
它们有什么不同,建议使用哪些?
<注意:指向调试程序或GCC选项的链接, http://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html#Debugging-Options
可能没有区别 - 取决于操作系统本机格式以及您希望调试信息的便携性。查看GCC手册调试选项 。
When I use gcc to compile C programs
I usually use -g
to get some debug information into the elf file
so that gdb can help me if needed.
However, I noticed that some programs use -ggdb
, since it's supposed to make the
debug info more gdb friendly.
How do they differ and which is recommended to use?
Note: A link to the options for Debugging Your Program or GCC, http://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html#Debugging-Options
It is possible that there is no difference - depends on the OS native format and how portable you want the debugging info to be. See GCC manual Debugging Options.
