Re: [Plplot-devel] Need small change to the way Ada bindings are built

[Jerry <lan...@qw...>]

OK--I got some great help from comp.lang.ada (as usual) and have learned how to make a .gpr file that references the .ali files and the corresponding .dylib when they are in separate directories. My original problem is solved in that I can now build PLplot using the 2011 GNAT (from an old version of source--not to confuse this thread with my other pending thread on the list) and subsequently bind and link my personal project.

I was pointed to a very nice document called Debian policy for Ada at
http://people.debian.org/~lbrenta/debian-ada-policy.html
which provided a clearer description of what needed to be done than the GPRbuild User's Guide.

It's still a mystery why my defective .gpr file worked with the 2010 GNAT tools.

Unless Alan thinks we have uncovered some testing issues, I'm ready to put this to rest.

Sorry for the fuss.

Jerry
