c++ - 仅 boost dynamic_bitset header

根据所有初步迹象,boost dynamic_bitset只是标题。

documentation暗示它只是标题:

The class dynamic_bitset is defined in the header boost/dynamic_bitset.hpp. Also, there is a forward declaration for dynamic_bitset in the header boost/dynamic_bitset_fwd.hpp.

该库没有出现在Getting Started 中的“非头文件”库列表中。文档:

Boost Getting Started

最后,使用 Boost 1.70.0 的本地系统上的 bootstrap.sh --show-libraries 命令没有将 dynamic_bitset 列为需要单独构建和安装:

The Boost libraries requiring separate building and installation are:
- atomic
- chrono
- container
- context
- contract
- coroutine
- date_time
- exception
- fiber
- filesystem
- graph
- graph_parallel
- headers
- iostreams
- locale
- log
- math
- mpi
- program_options
- python
- random
- regex
- serialization
- stacktrace
- system
- test
- thread
- timer
- type_erasure
- wave

但是,当我使用 bcp --list 列出依赖项以便仅使用此库时,包含 .cpp 文件:

因此我得出结论,bcp 拷贝不会只包含头文件。

Boost dynamic_bitset 真的只有 header 吗?如果是,我如何在我的项目中只包含相关的 header ?

最佳答案

来自文档:

It should be noted that in practice bcp can produce a rather "fat" list of dependencies, reasons for this include:

  • It searches for library names first, so using "regex" as a name will give you everything in the libs/regex directory and everything that depends on. This can be a long list as all the regex test and example programs will get scanned for their dependencies. If you want a more minimal list, then try using the names of the headers you are actually including, or use the --scan option to scan your source code.

  • ...

因此,您会得到一个庞大的依赖项列表,因为搜索包括本身不是仅 header 的测试和示例,并且具有更多非仅 header 的依赖项。

Is Boost dynamic_bitset really header-only

我认为没有理由怀疑这一点。

if so, how do I include only the relevant headers in my project?

根据引用的建议,您可以改为尝试:bcp --list boost/dynamic_bitset.hpp 以获得更精简的列表。
