Ada and X Windows programming.

Ada and X Windows programming.

[Jim Burns]

We are working with X and have been trying to pass callback procedures to a c
interface we've built to XView. We've got this working with Alsys, but the 
GNAT compiler barfs at the call in pragma.

Does anyone know a way round this? 
When will the GNAT compiler support the export pragma?

Thanks.

This is probably not the final solution but right now you can use
'gnatbind -n my_package.ali' it will generate the elaboration procedure
that you need to call from your 'C' code before using elements defined
in the package (although, I would recommend to use pre-elaborable
packages whenever possible to avoid all this fuss with defining and
calling the elab routine at the right moment)
By the way "pragma Export" is now implemented and will be in 2.04
