Replying to [comment:10 bonefish]:
> What apparently seems to be the problem is that the linker (...) even
requires the libraries to be listed in dependency order. That I would
consider a bug or at least a seriously missing feature.
It's by design. The second link has it in there:
{{{
Also in Natty, ld runs with the --as-needed option enabled by default.
...
The --as-needed option also makes the linker sensitive to the
ordering of libraries on the command-line. You may need to
move some libraries later in the command-line, so they come
after other libraries or files that require symbols from them.
}}}
Basically --as-needed links in only actually required libraries. Since
that lookup obviously only goes in one direction it's pretty much the same
as for static libraries now.
