Re: Binding or not binding

[Pascal Obry <pascal@obry.net>]

Ali,

I don't think there is a definite answer to this. It all depends on the
size of the library. An one-day-work rewriting in Ada is probably fine,
but when the work done on the C side is years ? For example in AWS we
bind to the Zlib, and OpenSSL libraries, it would be a waste of time to
recode both of them in Ada.

Another example, do you think it would have been wise to recode the Gtk+
library in Ada... certainly not :)

For such library I would bind to the C library.

Note that recent GNAT versions are now using the same object layout as
G++. It means that a GNAT tagged type can be mapped to a C++ class. This
will probably easy binding to C++ based libraries.

You're welcome :)
