gdb调试只能调试部分函数,为什么?

cjycompany

100多个源代码文件，有些函数调用gettext,SDL,freetype,freeWnn,自制的*.a
用g++编译，带 -g 参数。
main开始部分能单步跟踪，但是有些函数根本进不去，而且还next也过不去。
什么问题？

cjycompany

好像有些人认为是因为是没有带 -g.
如果问题这么简单就不会发提问了。

可能的问题是
1）有些源代码文件太大
2）函数内部有#ifdef等宏定义
3）c和c++共存。
哪位高人指点指点？

去掉-O

cjycompany

好像不行

newroot

gdb只能跟踪加入调试信息的程序，我看你程序只像gettext这些函数并不是你自己实现的，而是用库的，这些库在发行时并没有加入高度信息啊！

cjycompany

对阿,现在问题是我自己的写的函数进不去.
比如现在的问题是，我在main.cpp里加了aaa(),bbb()函数，aaa()能进去，但是这个bbb()怎么弄也进不去。
现在的做法只能是追加printf来打出信息了。

gettext好象是GNU定义的宏吧?

这个没仔细看过！！

不过像这样的情况好像还没见过耶！！加入了调试信息了，gdb无法跟踪!!

你break bbb()了吗
