-- If the `lib-version-info` field or the `lib-version-linux` field of

-- version into the SONAME field.
--
-- If a foreign library foo has lib-version-info 5:1:2, it should be
-- built as libfoo.so.3.2.1.  We want it to get soname libfoo.so.3.
-- However, GHC does not allow overriding soname by setting linker
-- options, as it sets a soname of its own (namely the output
-- filename), after the user-supplied linker options.  Hence, we have
-- to compile the library with the soname as its filename.  We rename
-- the compiled binary afterwards.
--
-- This method allows to adjust the name of the library at build time
-- such that the correct soname can be set.

~~~~~~~~~~~~

Suppose that the dynamic library depends on `base`, but not (directly) on
`integer-gmp` (which, however, is a dependency of `base`). We will link the
library as

    gcc ... -lHSbase-4.7.0.2-ghc7.8.4 -lHSinteger-gmp-0.5.1.0-ghc7.8.4 ...

However, on systems (like Ubuntu) where the linker gets called with `-as-needed`
by default, the linker will notice that `integer-gmp` isn't actually a direct
dependency and hence omit the link.

Then when we attempt to link a C program against this dynamic library, the
_static_ linker will attempt to verify that all symbols can be resolved.  The
dynamic library itself does not require any symbols from `integer-gmp`, but
`base` does. In order to verify that the symbols used by `base` can be
resolved, the static linker needs to be able to _find_ integer-gmp.

Finding the `base` dependency is simple, because the dynamic elf header
(`readelf -d`) for the library that we have created looks something like

    (NEEDED) Shared library: [libHSbase-4.7.0.2-ghc7.8.4.so]
    (RPATH)  Library rpath: [/path/to/base-4.7.0.2:...]

However, when it comes to resolving the dependency on `integer-gmp`, it needs
to look at the dynamic header for `base`. On modern ghc (7.8 and higher) this
looks something like

    (NEEDED) Shared library: [libHSinteger-gmp-0.5.1.0-ghc7.8.4.so]
    (RPATH)  Library rpath: [$ORIGIN/../integer-gmp-0.5.1.0:...]

This specifies the location of `integer-gmp` _in terms of_ the location of base
(using the `$ORIGIN`) variable. But here's the crux: when the static linker
attempts to verify that all symbols can be resolved, [**IT DOES NOT RESOLVE
`$ORIGIN`**](http://stackoverflow.com/questions/6323603/ld-using-rpath-origin-inside-a-shared-library-recursive).
As a consequence, it will not be able to resolve the symbols and report the
missing symbols as errors, _even though the dynamic linker **would** be able to
resolve these symbols_. We can tell the static linker not to report these
errors by using `--unresolved-symbols=ignore-all` and all will be fine when we
run the program ([(indeed, this is what the gold linker
does)](https://sourceware.org/ml/binutils/2013-05/msg00038.html), but it makes
the resulting library more difficult to use.

Instead what we can do is make sure that the generated dynamic library has
explicit top-level dependencies on these libraries. This means that the static
linker knows where to find them, and when we have transitive dependencies on
the same libraries the linker will only load them once, so we avoid needing to
look at the `RPATH` of our dependencies. We can do this by passing
`--no-as-needed` to the linker, so that it doesn't omit any libraries.

Note that on older ghc (7.6 and before) the Haskell libraries don't have an
RPATH set at all, which makes it even more important that we make these
top-level dependencies.

Finally, we have to explicitly link against `libffi` for the same reason. For
newer ghc this _happens_ to be unnecessary on many systems because `libffi` is
a library which is not specific to GHC, and when the static linker verifies
that all symbols can be resolved it will find the `libffi` that is globally
installed (completely independent from ghc). Of course, this may well be the
_wrong_ version of `libffi`, but it's quite possible that symbol resolution
happens to work. This is of course the wrong approach, which is why we link
explicitly against `libffi` so that we will find the _right_ version of
`libffi`.
