Hi guys
   I have installed MythtTV so successfully, but I encounted a very puzzle problem.So I need come up with this problem for sharing.I want to debug a program name mythfilldatabase  in MythTV ,Then I done like this:
$gdb mythfilldatabase
(...Omit inimportant info)
(gdb) run mythfilldatabase
Starting program: /home/mythtv-0.17/programs/mythfilldatabase/mythfilldatabase mythfilldatabase

编译的时候没加-g?

I did not know weather add "g" option to make. I just type:confiugre -->qmake mythtv.pro-->make , What do your meaning for "add g option "? How can I to do what your said?
Thanks

加g就是通知gcc在编译时产生调试所需的符号表，这要在Makefile中的CFLAGS中加，最好还要去掉gcc的优化选项-O2什么的，建议你研究一下linux下的基础编程知识。

Thanks ,With respect,I think that I currently needn't to resach Based-Programming in Linux deeply. Even thought thank your such detail help, I do not agree with your poinview. Maybe  you are expert on Linux-Programming, especially be  good at progrrmming NOT other aspect, But ....
