OpenCV的錯誤時，令CentOS

我試圖在CentOS 5.8安裝OpenCV 2.4.2，但我得到以下錯誤OpenCV的錯誤時，令CentOS

我的cmake上運行以下命令

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_EXAMPLES=OFF WITH_CUDA=OFF ..

謝謝。

你有最新的make和gcc嗎？ – Sam 2012-07-30 16:20:08

是的，一切都是最新版本。 – 2012-07-30 16:35:23

問題已解決。

我申請下面的補丁到〜/下載/ OpenCV的-2.4.2 /模塊/ features2d/src目錄/ freak.cpp

這個工作，但如果是在更多的Linux補丁友好格式（如diff-up或uprN）和一些評論會很好。你有沒有提交給OpenCV？ – CrackerJack9 2012-08-18 20:40:17
