这几天调整安装，发现有些文件安装到/lib下。就想复制到安装目录，这样影响更少。然后发现rpath有问题。怎么办？修改为当前路径最好。
- 当前路径的两种表示方法
.或者$ORIGIN
NEW_RPATH=.:/usr/local/lib/:/lib/aarch64-linux-gnu/
NEW_RPATH=\$ORIGIN:/usr/local/lib/:/lib/aarch64-linux-gnu/在编译的时候，大多使用ORIGIN。因为有特殊含义，所以这里进行了转义。
-
办法1
patchelf --set-rpath ${NEW_RPATH} libopencv_video.so
-
办法2
chrpath -r ${NEW_RPATH} libopencv_video.so
-
修改前

修改后
$ ldd libopencv_video.so

可以看到由编译的绝对路径，变成了相对路径。
