我使用C++在NetBeans 8.0上使用openCV 3.3.0在Ubuntu 16.10 LTS上構建OpenCV項目。_ZN4half5_eLutE未定義的OpenCV 3.3.0 build
編譯錯誤和警告免費。但是，在鏈接階段編譯失敗，因爲_ZN4half5_eLutE被視爲未定義。以下顯示鏈接過程和結果。

據我所知，有在libopencv_flann.a定義幾個類似的字符串，但它是包括在內。
我注意到'-lopencv_flann'出現在'-lopencv_imgcodecs'之前。如果後者依賴於前者，這可能會成爲問題。然後再一次，前者也出現兩次後。 – chris
我試着把-lopencv_flann放到最後，但仍然得到了同樣的錯誤。謝謝， – OtagoHarbour
你可以使用命令行進行編譯：'g ++ * .cpp -o test'pkg-config opencv --cflags --libs'-lpthread'？只是爲了確保你包含所有'.so'文件。 – zindarod
