Question

我正在尝试在我的CentOS 6.4上安装OpenCV-2.4.9。机。
我在〜/ Downloads / opencv-2.4.9中下载了源代码从那里，我做了'mkdir build; cd build'。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 ..

并且'做'-j2' 下面是我收到的消息（这是使用'make'重新运行的结果）

我做了一些搜索，但没有好的答案。任何人都能给我一个关于错误的暗示吗？

Answer 1

我遇到了同样的问题，我的解决方案是删除所有构建文件（或CMakeCache.txt）并再次使用cmake。

问题是cmake找到了一个32位的库而不是64位的库，它应该在/lib64/libbz2.so或/usr/lib64/libbz2.so中找到。有时cmake搞砸了并继续使用缓存变量。因此，如果您再次删除缓存并进行cmake，它应该找到正确的库。

OpenCV编译错误链接CXX共享库../../lib/libopencv_highgui.so /lib/libbz2.so.1：无法读取符号：文件格式错误
