C and ADA

[Brian]

Hi I have an ADA function that I'd like to call from my C program.

Is there any way to provide a .h file containing a C prototype for the
ADA function and then link the ADA with the C? Does anyone have any
experience of this?

I'm using a GNU setup on Linux.

Thanks.

C doesn't define how to mix C with other languages. I believe Ada does
define how to mix Ada with other languages, so you're better off asking
in an Ada newsgroup.

Ada (not "ADA"; it's not an acronym) provides mechanisms for
cross-language calls between Ada and C; C does not. The folks in
comp.lang.c won't be able to answer your question. I've redirected
followups just to comp.lang.ada, and I suggest that others do
likewise.

You can add a "pragma Export" to your procedure and compile it with
gnat. There is a chapter on mixed language programming in the GNAT
manual. But I think you might end up having to build the app with
gnat. Surely porting the procedure would be easier?

This process is described here (as well as the opposite process where
the main program is Ada);

Also, see the Ada Reference Manual:

FWIW, I've done this sort of thing using GPC, the GNU Pascal compiler,
with good results.
