無法從源代碼構建OpenCV

Question

我嘗試按照以下說明從源代碼構建OpenCV，但它始終失敗約17％。 我創建了一個臨時構建目錄，運行cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..隨后出現以下錯誤時，執行make 。

我嘗試在一個干凈的構建目錄中構建此文件，以sudo的身份運行它，並刪除CMakeCache.txt文件（有人出現類似錯誤的消息說這很有幫助）。

這是gcc-6.1的錯誤，請將您的gcc降級為gcc-5.3。

sudo apt-get install gcc-5.3 g++-5.3
rm /usr/bin/gcc
ln -s /usr/bin/gcc-5 /usr/bin/gcc
rm /usr/bin/g++
ln -s /usr/bin/g++-5 /usr/bin/g++

現在，您可以再次使用cmake。
