I'm trying to build rpb-weston-image with https://github.com/96boards/oe-rpb-manifest.git master branch, but encounter many errors related to graphics libraries dependencies, following is the error log

But the libraries do exist:

./build-rpb-wayland/tmp-rpb_wayland-glibc/sysroots-components/hikey/mali450-userland/usr/lib64/libwayland-egl.so

Does anyone encounter the same issue or know how to fix it? Any suggestions would be appreciated.

hikey is broken in Rocko and Master. @mrchapp is working on it.

Thanks, @fboudra

this issue is due to missing DT_SONAME entry in the precompiled mali shared library, actually someone should report this to mali team so they can add a proper soname during build before publishing.

OE shlib code checks for DT_NEEDED against a set of shlibs for deps however if thse shared libs do not have DT_SONAME then it does not create a rprovides for these sonames

Long story short you can workaround this by inserting a soname e.g. something like below will help your case

I reported this to the team (along with some other issues I found doing the debian packaging).
There was a suggestion that this lack of proper versioning may be deliberate, because the same binary pretends to be several different libraries with different soversions (libEGL.so.1 , libGLESv1_CM.so.1, libGLESv2.so.2, libOpenCL.so.1) so maybe it's not clear what DT_SONAME it should be using? The original reasoning may be lost in the mists of time.

This case is a good example of why it's a real-world problem. I'll feed that back.
