提升不建立所有库

Question

在project-config.jam中，我看到一行

$
# List of --with-<library> and --without-<library>$
# options. If left empty, all libraries will be built.$
# Options specified on the command line completely$
# override this variable.$
libraries =  ;$

仍然

bootstrap.sh --prefix=/my/target/location/
./b2 install 

不会构建所有库。只有以下一个：

Component configuration:

- atomic                   : building
- chrono                   : building
- container                : building
- context                  : building
- coroutine                : building

- timer                    : building
- type_erasure             : building
- wave                     : building

我遇到了问题，因为组件中的circular_buffer不可用。

Answer 1

并非所有Boost组件都需要构建到库中 - 许多是“仅标头”，因此整个实现在.hpp文件中定义。

看起来上面的组件列表只是那些需要相应库的组件，这就是“构建”步骤正在做的事情。

运行安装脚本并验证目标中是否存在include/boost/circular_buffer.hpp，因为这确实是一个仅限标题的组件。
