Question

我正在嘗試構建到Doge硬幣無頭錢包（類似於bitcoind），它似乎是引起錯誤的Boost，但我不知道如何解決它。

（Ubuntu的12.04）

當我執行 「讓-f makefile.unix USE_UPNP = - 」 我得到這個錯誤：

Answer 1

你需要對那些Boost庫鏈接，即添加-lboost_thread -lboost_filesystem -lboost_system到你的鏈接器命令行。

請參閱Link Your Program to a Boost Library瞭解更多詳情。

Answer 2

我遇到了同樣的問題，使用boost 1.55.0。

我用Boost庫nm和沒有包含含filesystem3

我假設升壓1.55.0刪除filesystem3，可能把它變成僅有頭模板但是這只是一個猜測的任何符號。我正在鏈接mongodbclient.a，我不想從源代碼重新編譯mongo（需要大量安裝程序）

移動到boost 1.49.0修復了這個問題。那些庫中有文件系統3。

Answer 3

我使用boost 1.62時遇到了同樣的問題。

但是，就我而言，由於我在Ubuntu 16.04上安裝了幾個升級版本，因此將庫和include目錄指向正確的文件夾確實有所幫助。

我做符號鏈接的包括文件夾和庫文件夾（升壓安裝自動完成）：

/usr/include/boost -> /usr/local/boost_1_62_0/boost

和

/usr/local/lib/libboost_thread.so -> libboost_thread.so.1.62.0
