I am using ActivAda 5.5 for Windows NT and I am having a problem using the 
posix dll (PSXDLL.DLL). When I run the program windows NT tells me that the 
dll initialization failed. Here the test program I am trying to use.

with text_io;  
with win32;
procedure pidtest is

    Max_Int_32 : constant := 2_147_483_647;                --   (2**31)-1 
    Min_Int_32 : constant := -2_147_483_648;               --  -(2**31)

    type Integer_32 is range Min_Int_32 .. Max_Int_32; 
    for Integer_32'Size use (32);
    
    -- getpid - get process identification
    function Getpid return Integer_32;
    pragma Interface (C, Getpid);
    pragma Interface_Name (Getpid,"_getpid");

  I : Integer_32;
begin   
    I := getpid;
    if i = 0 then
      text_io.put_line("getpid failed");
    else
      text_io.put_line(" pid is: " & integer'image(integer(I)));
    end if;   
end ;


I have the library c:\aa_552\lib\psxdll.lib in the modules line of the bind 
options and the search line. The program seems to bind just fine. I did notice 
in the ActivAda documentation (DLL Support Notes) the following information:

�Make sure the new RTS_NT.LIB library is used and not the one that was 
included in the version
5.5 product release.  The new library should have replaced the old RTS_NT.LIB 
in installation
directory by this DLL supplement install script INSTALL.BAT.�

If someone from Thomson is listening I would like to know where to get the new 
rts_nt.lib and install.bat files that are referenced in the above statement. I 
can�t find them on the CD ROM.

Is there anyone else out there who has done this and can offer some advice?

Thanks in advance for any help.

Unless something has changed recently, you can't run the Posix dll under
the windows subsystem.  That is, you can link you program to run under
various subsystems, like: windows, console, posix, native.  The Posix stuff
won't run under the Windows subsystem, and I believe the windows stuff
doesn't run under the Posix subsystem.

You may have to specify a different linker option to get your program
to run.  And I suppose it is possible that some other code (like the RTS)
is dependent on the Windows subsystem, which might preclude Posix ss stuff
altogther.  Then you have to build it as a separate program and using
interprocess communication to make it play.

Forgive my "unnetly" response, but why don't you call Thomson?

We haven't gotten many answers/solutions from our contact at Thomson. I 
thought I might get a response from someone who knows.
