我試圖建立的2.4所有版本，並在「鏈接CXX可執行../../bin/opencv_test_core」與他們全部失敗：錯誤建築OpenCV的2.4.x的「未定義參考av_opt_set @ LIBAVUTIL_51」

我的CMakeLists.txt文件是默認的，但我將其更改爲使用TBB，禁用了文檔並打開了詳細模式。
做LDD /usr/local/lib/libavcodec.so.54我得到：

任何人有任何想法，以什麼可能導致它，或者我能做些什麼來解決這個問題？我已經在這方面做了很長時間，並且處於虧損狀態。任何幫助將非常感激。
您可以嘗試關閉CMake中的'WITH_FFMPEG'選項並以此方式構建它，除非您需要ffmpeg支持。 – WildCrustacean
我能夠將ffmpeg從0.11降級到0.8來解決問題。不知道爲什麼會導致問題，但它是固定的。 – user1956554
