[Mono-dev] DllImport("__Internal") and libMonoPosixHelper static build

[Rafael Teixeira]

AFAIK, the DLLImport binding depend on loading information of dynamic
libraries, if you want to call something statically linked in the runtime
you'll need to move to using internal calls, but that means an extensive
rewrite of the the affected libraries both managed and native as the
protocol doesn't include automatic marshaling of managed types, and correct
versioning is a must to avoid crashes on incompatible ABIs.

Another possibility is to change the dynamic libraries binding mechanism to
search for statically linked symbols, not sure how complex this would be.

The best alternative is to fix the loader and keep the .so files around.

Just my two cents,
