Support for OpenWatcom

[MaiRat]

Hi,

I want to create a DOS/32-Bit application using the hxdos startup-code (or nt/nts). I set up a XP32/SP3 VM on VirtualBox with Additions and installed OpenWatcomV2 2025-09-01. Additionally, I extracted all HX-ZIPs (Version 2.22) to c:\hx.

I followed the instructions in owsupp\readme.txt, but the link-step missing a hxow.lib. In detail:

• system hxdos

• • hxow not found
• • missing symbols: _STACKTOP, _curbrk, _STACKLOW, _osmajor, _osminor, _psp, _Extender, _ExtenderSubtype, _Envptr, _Envseg, __uselfn, _dynend,
    _LpCmdLine, _LpPgmName

• system hxnt

• • all-fine

• system hxnts

• • Error! E3033: system block hxnts: directive error near 'disable'
• • After commenting out the "op disable 1030", the error "E2030: file clib3r.lib(cstrtwnt): multiple starting addresses found, already defined in initw3ow.obj(initw3ow.obj)" (already a ticket?!)

Is there anything I missed out in my environment?

system hxdos

1. instead of hxow.lib a single object module (spawn-hx.obj) is supplied.
2. missing symbols: module cstrtdhx.obj is for OW's stack calling convention only.

system hxnts: line "op disable 1030" should be changed to "disable 1030".

A fixed hxdev222.zip has been added to HX v2.22 - hxdev222a.zip. The hxow.lib has been reintroduced, now called hxows.lib and hxowr.lib ( for OW's stack/register calling convention ).

for me with this system hxnts fails with:

loading object files
searching libraries
Error! E2028: _g_hInstance is an undefined reference
creating a HX Extender (DOS PE, static Win32) executable
file duser32s.lib(cursor.OBJ): undefined symbol _g_hInstance
file duser32s.lib(ICON.OBJ): undefined symbol _g_hInstance
file duser32s.lib(Bitmap.OBJ): undefined symbol _g_hInstance

after using a function like ShowWindow();

after using a function like ShowWindow();

Although this can be fixed by adding the missing definition in DKRNL32/INITW32/INITW32.ASM I'd say that system hxnts should be used for console programs only.
