Boost Bimap在调试版本中占用过多内存 [英] Boost Bimap takes too much memory in debug build

问题描述

我正在使用很多形式的容器

I am using quite a few containers of the form

boost::bimap<boost::bimaps::multiset_of<std::string>, boost::bimaps::set_of<AnEnum> >

我在很多cpp文件中包含的头文件中定义它们(这是在我尽可能限制头文件的显示之后).在调试版本中创建的.a文件运行到1 GB以上(由于设备上无空间"错误，导致编译中途停止，因此编译时间自然呈指数增长.

I am defining them in a header file that is included in quite a few cpp files (This is after I limited the exposure of the header file as much as possible). The .a files being created in the debug build runs to above 1 GB (resulting in compilation stopping midway due to 'no space on device' error and naturally the compile time has increased exponentially.

使用的编译器是gcc 4.8.1.只是想知道是否有人使用boost :: bimap遇到了这个问题，以及他们为解决这个问题做了什么

The compiler being used is gcc 4.8.1. Just wanted to know if anyone has encountered this problem with boost::bimap and what they did to resolve this issue

推荐答案

我很可能每次您在不同文件中使用这样的bimap时，它都会专门导致巨大的代码重复.如果使用的是c++11，则应将它们声明为extern template，并仅将其专用于一个文件.请参见使用外部模板(C ++ 11)

I is very likely that each time you use such a bimap in a different file, it is specialized leading to huge code duplication. If you are using c++11 then you should declare them as extern template, And specialize it in only one file. See using extern template (C++11)
