Hi Chen,
I'm a little confused by your message.
You've replied to my email to the Yocto mailing list, regarding a problem I'm having with Yocto, by suggesting I email this list if I have a problem with Yocto.
Unless I'm missing something, that doesn't make a lot of sense. Can you please clarify?
Thanks
John

The libraries in question are part of OpenDDS, which I've cross-compiled for a Zynq-7000 target. At this point I don't want to include the build of the libraries in the Yocto (actually PetaLinux) configuration as it takes hours to build, so I just want to add the shared libraries that are needed into the image. However I haven't managed to get this to work in hours, if not days, of trying. Despite multiple attempts at an opendds.bb file, I continue to get issues with:

I uses the normal install to do the binaries, and oe_soinstall to work with the versioned shared libraries, as described in various places.

It then generates sonamelink and solink from the library details and creates symbolic links that point back to the copies of the library files in ${WORKDIR}. In doing that, the copy of the file that was placed there by the install line is overwritten with the symbolic link; is that normal? (I presume it must be otherwise no one would be getting oe_soinstall to work!).
