使用Clang編譯基於OpenCV的項目

我剛剛在64位Ubuntu機器上對叮3.4進行了全新安裝，我試圖編譯一個使用OpenCV的項目。 Clang和OpenCV庫都是使用apt-get從ubuntu存儲庫安裝的。使用GCC可以正常工作。構建過程由CMake管理。使用Clang編譯基於OpenCV的項目

當我使用鏘運行生成我得到以下錯誤：

他們似乎OpenCL的關係。我該如何解決這些鏈接器錯誤？

如果您嘗試使用cmake編譯opencv，該怎麼辦？通常cmake會對編譯器做一些額外的檢查 – nkint

@nkint你的意思是獲取OpenCV源代碼並使用cmake編譯自己？ –

是的，確切地說。通過包管理器安裝蛋糕，從github下載OpenCV源代碼，嘗試'mkdir build; cmake ..' – nkint

嘗試手動編譯它。有時通過數據包管理器安裝依賴關係時會出現一些問題。 CMake是一個非常強大的工具。它執行檢查編譯器，平臺等

安裝CMake（通過數據包管理器），並且從庫下載的最後的OpenCV源：

https://github.com/Itseez/opencv

和型外殼上的標準命令蛋糕房：

$ cd opencv_path 
$ mkdir build 
$ cmake .. 
$ make

執行的蛋糕還可以輸出一些重要的信息，最好是閱讀：）

opencv的CMake腳本也爲您提供了配置CUDA和OpenCL的好方法！

所以，我猜測與Clang和libC++手動編譯將不再使代碼與gcc和libstdC++編譯？使用OpenCV進行編碼時，是否無法在兩個編譯器之間輕鬆切換？ –

我猜它缺少第二行和第三行之間的「$ cd build」。對不起，重溫這樣的老問題，但它在谷歌搜索高票價 –
