Ada/Motif binding

Ada/Motif binding

[PR MITTON]

I am trying to find a binding of Ada (preferably '95) to Motif.  The Dec 
binding looks the best that I have found so far but I am having difficulty
getting the program to compile.

The problem is in the xm_string.c file (created from the xm_string_.pic2a 
file).  When I attempt to compile the program the following error message
comes up:

	Undefined	first referenced
	symbol		in file
	XtShellStrings	/var/tmp/xxxx
	_XmStrings	/var/tmp/xxxx
	XtStrings	/var/tmp/xxxx

	ld: fatal: Symbol referencing errors. No output written to a.out

It is the only error.

I am using gcc on a Sparcstation running Solaris.

Anyone have any useful ideas as to the cause of this error and the
question of binding Ada to Motif in general?

Thanks

Pete

The Intermetrics Motif/Ada 95 binding can be downloaded from
ftp://ocsystems.com/xada/motif.tar.gz.  You will also need 
their X11/Ada 95 bindings:  http://www.inmet.com/~mg/x11ada/x11ada.html.

For information on Ada 95 bindings to other X toolkits, see
http://www.ocsystems.com/xada.

It appears that you have not provided the names of the Xt and Motif
archive files to the linker.  Proper use of the '-l' and '-L' switches
will probably correct the problem.  If you believe you are already 
using these switches correctly, please provide more detail.

There is no restriction on the use of the software on another architecture in
the license of the package.   The license is the basic feel free to do as
you wish with the product as long as the DEC copyright notice remains but
don't sell it without their permission.

We are only using it for educational purposes as the binding looks to be 
better Ada for people learning Ada from scratch.  The Intermetrics binding
looks a lot more like C than Ada.
