compiler errors, include paths, and gnatreg

compiler errors, include paths, and gnatreg

[Aaron W. Myers]

Thanks for reading

I've finished my first year studying ada at my university and enjoyed
every second of it.  My problem is that I have a lot of questions and
I'm not around my teachers to get them answered.

I'm trying to compile the examples sent with AdaSockets v0.1.19 for
Windows.  I want to do this by running make.bat but when i do i get
pagers of errors that say something like
compiling.error: "sockets-thin.adb" and "tcprelay.adb" compiled with
different GNAT versions
and stuff like this
error: "s-stalib.adb" must be recompiled ("a-except.ads" has been
modified)

It says that i need to change my ADA_INCLUDE_PATH and ADA_OBJECTS_PATH
environment variables to point to the adapower directory, but i don't
know how to do this.

and it says i can use gnatreg to do that too, but i don't understand
what that utility does?

Can anyone answer my questions?  thanks a lot!

Sincerely,
Aaron W. Myers

That probably means what it says: that the object code of these files
have been compiled by a version of GNAT different from what you are using.
Try recompiling them.

On old versions of windows, that use autoexec.bat, add the lines
set ADA_INCLUDE_PATH=<your path here>
set ADA_OBJECTS_PATH=<your path here>

On newer versions select 'My Computer', click on properties, go to the
advanced tab en press the 'Environment variables' button.

With gnatreg you can tell the compiler where to find files using the
registry instead of environment variables. Run it for more info.

You migh be better off using the Sockets library that is included with
GNAT. See the Reference Manual under 'The GNAT library'.

Sounds like you need to compile you adasocket library with the compiler
you use. Which compiler and which version? (Looks like GNAT, but which
version?)
