AdaTutor Compilation with GNAT

AdaTutor Compilation with GNAT

[George]

Dear Listers,

I refer to the article

http://groups.google.com/group/comp.lang.ada/browse_thread/
thread/6192a34d0c9ffe5b/177a4ab5525a77a2 .

I followed the instructions of PRINTME.TXT "APPENDIX D:  INSTALLING 
AdaTutor ON OTHER COMPUTERS" on page p. 41ff. The steps 1. to 8.
worked perfectly.

I tried to compile AdaTutor as mentioned in step 9., page 43, of 
PRINTME.TXT on my Debian GNU Linux 5.0 Lenny with GNAT 4.3.2 / gcc-4.3 
using

gnatmake ADA95.ADA and
gnatmake VANILLA.ADA .

Neither does compile. gnat says:

gcc-4.3 -c -x ada ADA95.ADA
ADA95.ADA:35:01: end of file expected, file can have only one compilation 
unit
gnatmake: "ADA95.ADA" compilation error

As I am new to Ada, it seems that GNAT expects the specification and the 
body of a package to reside in different files. In the sources of 
AdaTutor, specification and body reside in one .ADA file.

Is there a way to tell gnat to accept that format? Is there a program 
that can separate specification from body? Do I have to use a different 
compiler? Is there another way to fix that?

Kind regards

George

This is correct: GNAT requires one compilation unit per file. Try using gnatchop 
to break the files into something that GNAT can handle.

gnatchop ADA95.ADA

should break it into custom_io.ads and custom_io.adb.

gnatchop VANILLA.ADA

should do the same.

Many thanks for your help. This did the job.

There are ways to make GNAT accept more than one comp unit per file.
Consult the docs if you really want to do that.

But gnatchop is really the simplest way to go.
