g++ - 修复共享库 g++ 上的断开链接

Question

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

问题是，有没有办法在不重新编译整个源代码的情况下将这个可执行文件链接到新的共享库？我该如何修复这些断开的链接？

running ldd:

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

如果 OpenCV 2.3 版与 2.2 版二进制兼容，即如果 ABI没有进行重大更改，您可以使用 symbolic links 解决此问题:

# 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
