我正在使用 cmake 和 Visual Studio 2019 來構建我的專案。我的 boost 版本是 1.72，我libboost_python27-vc142-mt-x64-1_72.lib在目錄中生成boost_1_72_0\stage\lib了b2.exe.
.sln我用cmake生成了檔案。然后我在 Visual Studio 2019 中構建專案。但是，它最終出現了錯誤LNK1104: cannot open file 'libboost_python27-vc142-mt-x64-1_71.lib'
我真的不明白為什么它要求版本 1_71 而不是 1_72 的 libboost_python。我從未在任何檔案中引入版本 1.71 請求。那么它應該如何呢？我怎樣才能讓它發揮作用？

uj5u.com熱心網友回復：
我現在知道原因了。在我的專案檔案夾中還有另一個包含一些頭檔案的 boost 目錄。我錯誤地包含了 boost 目錄并依賴于 boost 1.71 ....
