Win32Ada and GNAT 3.09

Win32Ada and GNAT 3.09

[Kam Sing Tso]

I tried to compile Win32Ada release 3.0 with GNAT 3.09 but failed with
the following error message:

D:\WIN32ADA\src>gnatmake withall
gcc -c withall.adb

win32-winnt.ads:2659:05: representation item appears too late
gnatmake: "withall.adb" compilation error

Has anyone successfully built win32ada with GNAT 3.09?
I'd appreciate it very much if you could share your experience.

Yes, after modifying win32-winnt.ads (-> moved some pragmas, which
appeared to late in the code).
However, I still have some linking problems.

The following mail from Dr. Martin C. Carlisle solved my
problem.  Thanks.

-----------------------------------------------------------------------

I attempted to post the following message to comp.lang.ada
I doubt it made it.  It might be a help if you post it for me:


Following are my experiences with compiling a large Win95 using
gnat 3.09:

Compilation is *much* slower than using ObjectAda v. 7.0  -- this
is probably because I am using a version of their gbObjects, and
the ads file is huge, and is "with'ed" in many of my packages.

The win32-winmain.adb file is incorrect.  Use the one for ObjectAda,
not for gnat.  (replaces "echo_..." with "rts_get...")

When compiling win32-winnt.ads, I got 4 "representation clause too 
late" messages.  Moving the pragma's from the private section next to
the type declaration fixed this.

To use resource scripts, you need both the resource compiler "rc",
and "cvtres" (not included). 

Also, you will need to have the following pragma somewhere:

pragma Linker_Options("c:\gnat304a\win32ada\lib\win32ada.a");
(of course change the path)

To build, do "gnatmake <name of main program>",
when it reaches gnatlink, it will fail-- you must 
redo the "gnatbind -x" command, and then the "gnatlink" command
adding the option "-mwindows".

Actually, you can use the pragma:

pragma Linker_Options("-mwindows"); 

and avoid having to run gnatlink manually.  This is new (didn't work
in gnat 3.04a).

set ADA_INCLUDE_PATH=c:\usr\local\ADAINCLUDE;c:\gnat304a\win32ada\src
set ADA_OBJECTS_PATH=c:\usr\LIB;c:\gnat304a\win32ada\src
set C_INCLUDE_PATH=c:\usr\INCLUDE
set LIB=c:\usr\LIB;c:\gnat304a\win32ada\src
set COMPILER_PATH=.;c:\usr\bin;c:\usr\bin\gnu_ld
set LIBRARY_PATH=.;c:\usr\bin;c:\usr\LIB;c:\gnat304a\win32ada\src
set PATH=%PATH%;c:\usr\bin

This works, but is a guess without reference to documentation.

There are sample programs in the win32ada binding from :

Good luck!
