OpenCV编译错误链接CXX共享库.//lib/liboopencv_higiguid.so/lib/libbz2.s

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。
从那里开始，我进行了mkdir构建；cd构建'。然后是

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 ..

并且确实"制作了-j2"
下面是我得到的消息（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。有人能告诉我出了什么问题吗？

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cmake。

问题是cmake找到的是32位库，而不是64位库，后者应该在/lib64/libz2.so或/usr/lib64/libz 2.so中找到。有时cmake会出错，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。
