假设有这样的东西:
#include <map>
int main(){
std::map<int,int> m;
m[1] = 2;
m[2] = 4;
return 0;
}
我希望能够从 gdb 中检查运行该程序的地图的内容.
如果我尝试使用下标运算符,我会得到:
I would like to be able to inspect the contents of the map running the program from gdb.
If I try using the subscript operator I get:
(gdb) p m[1]
Attempt to take address of value not located in memory.
使用 find 方法不会产生更好的结果:
Using the find method does not yield better results:
(gdb) p m.find(1)
Cannot evaluate function -- may be inlined
有没有办法做到这一点?
Is there a way to accomplish this?
我认为没有,至少如果你的源代码经过优化等没有.但是,有一些 gdb 宏可以为你检查 STL 容器:
I think there isn't, at least not if your source is optimized etc. However, there are some macros for gdb that can inspect STL containers for you:

不过,我不使用这个,所以YMMV
However, I don't use this, so YMMV
这篇关于使用 gdb 检查标准容器 (std::map) 内容的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持html5模板网!
