hi,
i'm now doing some hard work around on optimizing some packages while
testing out -Wl, --no-undefined and forced --Wl, --as-needed on
my world set. as i predicted i found out quite a lot of packages that
don't link in the correct way. an example is apr-util. i've started to
work
on it and found out that for some unknown reason it wants to link
against itself when compiling the odbc parts. here's the interesting
part of
the build:

as you can see i've added the -lapr-1 library to be able to have more
undefined symbols go away. the problem
is that the symbols that are still undefined are present in
libaprutil-1 (which is itself as you can see from the
following output).
# nm -D --defined-only /usr/lib64/libaprutil-1.so | egrep
'apr_bucket_shared_copy'
# 000000000000c695 T apr_bucket_shared_copy
now, from my knowledge these should be fixed inside the includes,
which is there. the thing that i don't understand
is why the linker finds these symbols undefined. i don't have so much
knowledge about linker functionality so i'm
asking out for some help on the matter.
thanks.
