Hello,

I have problems installing GLADE for Gnat 3.14p on WinNT.
I installed Gnat 3.14p without problems.

I use the following installation dir for Gnat and its components like
Glade, Asis etc:
      c:\ada95\compiler\gnat

So I try to install from
      c:\ada95\compiler\gnat\glade-3.14p-src

To install I give the commands
      ./configure --prefix=../../glade      (--prefix=../glade does not
work)
      make install
to install all in
      c:\ada95\compiler\gnat\glade

Problem 1)
Installing the filters does not work. So I simply comment the following
lines in /garlic/makefile:
#install-zlib: libz.a install-dirs-local
#    $(INSTALL_DATA) libz.a $(GARLIC)
#    $(RANLIB) $(GARLIC)/libz.a

I encountered this problem already in the 3.13p version but managed to
install Glade and execute an example.

I get the following dir structure
c:\ada95\compiler\gnat\glade\
                              bin        -- gnatdist.exe
                              lib\garlic -- sources, ali, libgarlic.a


Problem 2)
This one is more severe.
When executing gnatdist it crashes. After altering the last choice in the
exception-handler in the XE_Build (gnatdist) main procedure to
----------------------------------------------------------
    when E : others =>
       Ada.Text_IO.Put_Line (Ada.Exceptions.Exception_Information (E) &
                             GNAT.Traceback.Symbolic.Symbolic_Traceback
(E));
       Message ("*** unknown error");
       raise;  --  hope GNAT will output its name
----------------------------------------------------------

and a rebuild with the options to see the traceback I get:

----------------------------------------------------------
bash-2.05a$ gnatdist
Exception name: CONSTRAINT_ERROR
Message: xe_utils.adb:911

gnatdist: *** unknown error

Execution terminated by unhandled exception
Exception name: CONSTRAINT_ERROR
Message: xe_utils.adb:911
Call stack traceback locations:

bash-2.05a$
----------------------------------------------------------

The line in question in xe_utils.adb is
      Add_Str_To_Name_Buffer (GARLIC.all);
A few lines before the statement
       GARLIC := Get_GARLIC_Dir;
probably returns a null string_access value.
I could track the problem down to a call to
      RegQueryValueEx

So my installation is probably not correct but I'm stuck.

Thanks for any help.
