dynamic/shared libraries for darwin?

[Andreas Tobler]

Hi,

is anybody working on dynamic libraries for darwin? (c, c++ ....)
I see in newer libtool.m4 some support for shared/dynamic liraries. But 
afaik this only works with more recent autoconf than we use in gcc.

Is this the only part which is missing ? Or, I guess, there must be some 
more hurdles? (code must also be shared library capable/clean?)

I wanted to try some dynamic libraries for libffi, but then I have to 
replace at least the libtool.m4 in the gcc top dir. And this may screw 
up things up to non usability. I could try, but I'd like to hear some 
opinions on this.

Do apple people plan such dylibs on gcc level? Or is this a future 
future wish list item?

Thanks for any hint.

Andreas

C (such as libgcc) might be reasonable. But bear in mind, we have 
binary compatibilities requirements that span decades, not just one 
major release.  We avoided shipping C++ libraries in the past as we 
didn't have the resources and time to devote to the problem.  In fact, 
we avoid C++ system libraries, as it isn't abi stable.

I don't think anyone around here it doing much.

I remember back a mail from Stan about that.

Ok, I see. But what would be the steps to start with dynamic libs for 
libffi, boehm, libgcj? In boehm there is some preliminary support in the 
next release. Needs some coding though. For libffi I guess I would be 
the one who should start? And in the same turn also for libgcj.
In these three you don't have compatibilities ;)
