Compiling DOSQuake on DOSEMU or DOSBOX?

I'm trying to compile DOSQuake with DJGPP on some kind of emulator. Has anyone tried this before? Is there a generic makefile to work with DJGPP?

Dosbox won't do it and will make gcc crash, so i'd advise something of a polished virtual machine with win9x to do it (like Qemu, Vmware)

q1source.zip lacks a DJGPP makefile so you'll have to make one.

I *did* compile Quake on DOSBox, but it's very slow.
It builds without problem on XP with newest DJGPP toolset (or rather it did a year ago).

Here's my never-finished and semi-abandoned source port. Pay attention to the "dos" branch which contains some DOS-specific fixes.

Is there a generic makefile to work with DJGPP?

https://github.com/Azarien/SoftQuake/blob/dos … Quake/quake.mak

Also, instead of setting up a Win95 image on VirtualBox or something, could it be possible to compile with OpenWatcom and run with DOSEMU?

I think porting to OpenWatcom would require major changes to the code.

EDIT: the above DOS branch supports some new console commands (cmdlist, cvarlist, max_fps, in_mlook, crosshair 2) and has smooth sky scrolling. Other new features (like .ogg playback or completely rewritten DirectDraw code) are Windows-specific.

When trying to build your branch on DOSEMU, i got several crashes.

ERROR: MFS: couldn't find root path /media/CDROM

It would be even more helpful if would recompile DOSEMU and reproduce this
bug with "debug on" in compiletime-settings.
Page fault: write instruction to linear address: 0x005107f4
CPU was in user mode
Exception was caused by insufficient privilege

I'm going to try on a Win98 VirtualBox soon.

FWIW when I compiled the dos version of Engoo (back when it did support DOS in 2010) I used a Win98SE VirtualPC 2007 guest to do the deed. QIP Quake has long filenames so that may be an obstacle for some environments with dos only

I never used DOSEMU and I don't know why it crashes.

I just compiled the same code with the latest DJGPP tools (GCC 7.1.0) on 32-bit Windows 10 Creators Update. The compiled game runs in DOSBox 0.74.

Does the final DJGPP run on 16-bit DOS?

I don't have any DOS machines at hand. I tried on VMware Player with DOS 6.22. The game works when run with -nosound parameter, otherwise it crashes. I guess this is vmware issue. 320x200 is too fast and stuttering, while higher resolutions are quite low on fps. But again, I'd blame vmware which is not a gaming platform.

There's also a cosmetic bug apparent in the open-source version of Quake (1.09) for DOS (the latest official DOS version of Quake was 1.08)

There are 4-pixel wide borders at the left and right edges of the screen:

It's the same kind of border that normally appears when you press the minus key to make the game area smaller.
The bug doesn't appear in Windows. I don't know the cause, but it is present in Id's original source.

That's definitely a gaffe id made in the source release (affects Winquake too). Note that Winquake's last release was before they had multiple GLQuake releases so they didn't bother to check on this

QIP fixes it and it should also be easily fixable itself.

Unfortunately, QIP fails to build with DJGPP, both on Win10, Win98 and DOSBOX:
