OpenCV编译错误Linking CXX共享库../../lib/libopencv_highgui.so/lib/libbz2.so.1 : could not read symbols: File in wrong format

Question

我正在尝试在我的 CentOS 6.4 上安装 OpenCV-2.4.9。机器。
我在 ~/Downloads/opencv-2.4.9 中下载了源代码。
从那里，我做了'mkdir build;光盘构建'。然后做了

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON --enable-shared ..

并做了“make -j2”。
以下是我收到的消息(这是仅使用“make”重新运行的结果)

我做了一些搜索，但没有好的答案。谁能告诉我哪里出了问题？

Answer 1

我有同样的问题，我的解决方案是删除所有构建文件(或 CMakeCache.txt)并再次 cmake。

问题是cmake找到的是32位库而不是64位库，应该在/lib64/libbz2.so或/usr/lib64/libbz2.so中找到。有时 cmake 会搞砸并继续使用缓存的变量。因此，如果您删除缓存并再次 cmake，它应该会找到正确的库。
