在VS2012項目上編譯Boost C ++庫

Question

我正在嘗試構建一個具有Boost和OpenCV依賴項的項目。 具有類似依賴項的其他項目似乎工作正常，但這會引發以下錯誤：

這可能是什么問題？

我已將宏輪的名稱更改為其他內容，現在已將其更改為過去的這些錯誤。 但現在，又出現了另一個錯誤：實際上這是一個Linux實現。 我試圖在Windows中運行它，因此我在windows中添加了timeoftheday實現代碼。

Answer 1

看起來有些東西正在聲明一個名為'round'的宏。

在您的錯誤中，請參閱以下行：

1>C:\boost_1_54_0\boost_1_54_0\boost/math/special_functions/round.hpp(20): warning C4002: too many actual parameters for macro 'round'

在任何庫依賴項和您自己的代碼中進行文件范圍的#define round搜索。

根據定義的內容，您可能有幾個選項來解決問題：

• 不要包含標題
• 如果您可以在構建設置中包含某些預定義的宏，請查看標題是否未定義round 。
• #undef在包括提升之前回合
• #include預編譯頭中的頭和#undef round
