[Buildroot] RISC-V Shared Library Locations

[Mark Corbin]

Hello

I've been looking at the RISC-V shared library issue reported by
Christopher McCrory[1]

For  RISC-V the glibc trusted directories for libraries are /lib64/<ABI>
and /usr/lib64/<ABI>, so for example, /lib64/lp64/ and /usr/lib64/lp64/
instead of the more common /lib64/ and /usr/lib64/. When you add extra
packages that require shared libraries the libraries are installed to
/usr/lib64/ and are therefore not found.

I was wondering if anybody has any thoughts on where/how this should be
fixed-up?

...modify package makefiles to install libraries to the 'ABI' locations?
...add LD_LIBRARY_PATH or ld.so.conf to the skeleton image and include
the 'non-ABI' locations?
...modify the glibc build configuration to use the 'non-ABI' locations?
...generate a set of symbolic links for each library file to point from
the 'ABI' locations to the '.../lib64' directories? For example,
/usr/lib64/lp64/libncurses.so -> ../libncurses.so

Any ideas would be much appreciated.

Thanks

Mark
