Using Gnat Ada and gtkada Glade

Using Gnat Ada and gtkada Glade

[tonyg]

I successfully used the GUI builder glade 10 years ago to make a
desktop application. I have a need for it now and I went back to use
it and I notice a few strange (to me) changes have been made and there
is no button to build the specifications (and bodies) . I am using
ubuntu 10.04 and the related gtkada gnat gnat-gps etc.
  Does anyone know how to build the specs from the glade file?

On further investigation gate2 seems to be the way however I am not
convinced I am using the right version of gate with the right version
of glade.

I am using glade 3.67 on ubuntu 10.04 with gtkada 2.14 and I am
getting a constraint error from a simple test glade file when using
gate2.

Does anyone know if there are incompatibilities here, in fact is
anyone else here using gate2 with glade 3.67 ?

I got a problem like this on Glade-2 for Windows. There is a button to Build the code, but it returns:

all.ada:1:01: compilation unit expected
all.ada: parse errors detected
all.ada: chop may not be successful
no compilation units found
no source files written

But entering the batch, I found out that if one executes 
   gate-in.exe project.glade > all.ada
   gnatchop -w all.ada
it generates the source codes. But it does not generate the project_main.adb file, what is my issue.

Maybe you can look for an application like gate-in in your ubuntu gtkada installation (could be a hint).

That would be /usr/bin/gate2, which calls
/usr/lib/ada/adalib/gtkada2/bin/gate2-in.exe.

I've solved the problems I had before (I'm on a new set - trying to
task with a gtkada fronted :) )

What I discovered -

1) Ubuntu 10.04 has a bug where gate-in.exe is contained in an /usr/
lib/ada/adalib/gtkada2/exe/ directory rather than the /usr/lib/ada/
adalib/gtkada2/bin/ directory where gate is looking for it. So I
created the bin directory and copied it across.

2) gate does not like the 'table' container widget. So now I am using
Vertical boxes as containers. (Gate generates a constraint error with
tables). So watch your widgets!

Good to see other folk are using gtkada. I just noticed that Dimitry
Kazakov has made a gtkada contributions package which does something
with gtkada tasking so I am going to take a look. For those of you who
do not know, Dimitry has been sent from the future to help ada
programmers.

OK, that means you had a version of libgtkad2-bin older than 2.14.2-2
(the current version is 2.14.2-4). And thanks to Nicolas Boulenguez
for finding and fixing this bug 10 months ago:

Given the hard work Ludovic, Xavier and some others are giving to make 
sure Ada on Debian is in good shape... I think so!

No offense taken, quite to the contrary :)
