Hi,

When I build a yocto image, I added some packages into IMAGE_INSTALL, such as
boost, thrift, etc. I notice in the target OS image, the shared libs don't the
symlinks. But in the SDK image, the symlinks are there. For example,
lrwxrwxrwx 1 root root       22 Oct  2 16:41 libboost_filesystem-mt.so ->
libboost_filesystem.so
lrwxrwxrwx 1 root root       29 Oct  2 16:41 libboost_filesystem.so ->
libboost_filesystem.so.1.75.0

Is there a way to add the symlinks to the target image as well?
With the symlinks, I assume we can run an old application even the dependent
lib is a newer version?
The symlinks will be in the XXX-dev packages so boost-dev probably has them for
boost. They aren't needed on target unless you're compiling things which is why
they're separated out.

Cheers,

Richard
