Building GNAT GPL 2006 Glade, I find the examples don't build correctly,
and a couple that build crash:

The two source files I used are:

MD5 Sum
6504bed94037ac5ccc9e80f1831104f8  gnat-gpl-2006-i686-gnu-linux-libc2.3-bin.tar.gz
8ed3151978111ce6c26a857d3d4642ed  tools/glade/glade-gpl-2006-src.tgz

The examples directory Examples/MultiPro fails to build.

On line 636 of glade-2006-src/Examples/MultiPro/s-gaprxy.adb a call is made:

Soft_Links.Set_Stamp (From_SEA (Data));

Which appears to call a function defined at line 271 glade-2006-src/Glade/s-gasoli.ads

--    procedure Set_Stamp (S : Float);

Which, as you can see, is commented out.  The build therefore fails.

Is there are more recent version of these files which will build?

I have tested all the examples that build on three different machines.
Examples/Eratho/dynamic and Examples/Eratho/cycle fail in deadlock
on Fedora Core 5, Debian and Red Hat distributions.

Has anyone here managed to run these examples?

I have emailed gnat-gpl@adacore.com
