修复共享库 g++ 上损坏的链接

Question

我有一个链接到 opencv 2.2 的可执行文件。但是，我已经删除了 opencv 2.2，并安装了 opencv 2.3。

问题是，有没有办法将此可执行文件链接到新的共享库，而无需重新编译整个源代码？我该如何修复这些损坏的链接？

running ldd:

    linux-vdso.so.1 =>  (0x00007fff17fff000)

如果 OpenCV 版本 2.3 与版本 2.2 二进制兼容，即如果 ABI 没有进行重大更改，您可以使用符号链接解决该问题：

# ln -s /usr/lib/libopencv_core.so.2.3 /usr/lib/libopencv_core.so.2.2
# ln -s /usr/lib/libopencv_imgproc.so.2.3 /usr/lib/libopencv_imgproc.so.2.2
