Dear all,
Our application comes with its own glibc version. We don't want to
bother users with manual ldconfig updating. Instead we are looking for
how to re-use the system-default glibc's configs as much as possible.
Unfortunately, ld cache may be non-portable across glibc versions. What
could be done about that? I think one can try to override application's
glibc call to _dl_load_cache_lookup with call to system's glibc, and it
will lookup in its compatible ld cache. But I'm not sure if this path
covers all possibilities. Do you see any better solution?
Thanks,
- - D.
