升壓不是所有建設圖書館

Question

在項目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 

不建的所有庫。僅下面的一個：

Component configuration: 

- atomic     : building 
- chrono     : building 
- container    : building

我所面臨的問題，becaues circular_buffer心不是在組件中可用。

Answer 1

並非所有的Boost組件都需要內置到庫中 - 很多都是「僅標頭」，因此整個實現在.hpp文件中定義。

它看起來像上面的組件列表只是那些需要相應的庫，這是'構建'步驟正在做的事情。

運行安裝腳本並驗證目標中是否存在include/boost/circular_buffer.hpp，因爲這確實是僅包含標頭的組件。
