BUG? NASM compiled by RSXNTDJ running under HXRT (Developers)

Hi, I started a new thread so it'd be easier to read / reply:

Really? Okay.

Me either. Besides, EMX itself requires VCPI which modern Windows disallow, so I think it's moot. (And I think EMX.EXE is only for DOS anyways, the .DLLs etc. are for OS/2, hence most EMX apps these days are compiled for OS/2 only.)

Wow, that's a monster of a 486 (32 MB, heh). But okay, it's probably just another MOSS bug, then don't worry about it.

Yeah, I forgot that you'd have to setup RSXNTDJ and then compile it, which is easier if I do it for you. It's not that important of course, but it'd be nice to know why it doesn't work (since it works fine via hxdosld using RSX.EXE):

* nasm-rsx.zip
* nasm-0.98.39.tar.bz2
* rsx.zip (Rod P.'s collection of all RSX-related files, some outdated, 25 MB !!)

NASM-RSX.ZIP includes the following:

NASM-RSX.ZIP nasm.exe 147,176 (340,480) Feb,23,2009 04:32:58p [Deflat] ndisasm.exe 63,009 (152,576) Feb,23,2009 04:33:00p [Deflat] makefile.dj 1,400 (4,693) Feb,23,2009 04:32:44p [Deflat] rsxnt.dll 28,431 (60,416) Jan,06,2002 07:56:50p [Deflat] rsx.exe 54,957 (111,900) Feb,09,2000 06:59:32p [Deflat] copying.rsx 672 (1,486) May,12,1998 07:35:32a [Deflat]

Note that I used GCC 2.95.3 (DJGPP 2.03p2) with RSXDJ151.ZIP but with latest RSXNT.DLL (60416 bytes, Jan. 6 2002) and RSX.EXE (version 5.24, 111900 from Feb. 9 2000) from RSXNTDJ16BETA2.TAR.GZ. Rainer S.'s page is long dead, so I'm not 100% sure where to find the srcs to 5.24 of RSX, but srcs for 5.21 appear to be in RSX521S.ZIP. (I know that probably doesn't matter, just a good faith effort to comply with licenses. Feel free to request some files via e-mail if Rod's 25 MB collection is too annoying to download.)

EDIT: How the heck did this get in "Announce"?? rr, please move, thanks! :-)

Thanks for your efforts! It was a bug in HX's DKRNL32 module ( function GetFileType() didn't set last error if it returned FILE_TYPE_UNKNOWN ). It's fixed in the "WIP" version of HXRT, see http://www.japheth.de/hx.html
