Reminds me, while looking for the missing files, I found https://wkiri.com/projects/atris/atris-sounds-1.0.1.tar.gz, probably the same as you found.

Found the missing files. Built fine, keys seem jerky, perhaps needs sdl.ini.
I committed some changes including the missing .protos/

Hello Dave

Please, if you got the time check also Alizarin Tetris.
- https://github.com/OSSGames/GAME-SDL-PUZZLE-Alizarin_Tetris

Regards

Seems to be missing some pieces,
Code: [Select]
config.status: error: cannot find input file: '.protos/Makefile.in'

Edit:
Removing the reference from configure.in results in,
Code: [Select]
Makefile.am:50: error: required directory ./.protos does not exist
make: *** [Makefile:120: Makefile.in] Error 1

Thanks a lot Dave.

Let me know if it is fine how I packed Rock Dodger.

I had the sdl DLLs in the source for testing, they should be removed and also do a make clean to shrink the size.
Edit: Otherwise fine

Quote
I hope I uploaded the source code correctly on Github:
- https://github.com/OS2World/GAME-SDL-ACTION-RocksnDiamonds

Regards

Update: Corrected version on the file.

It is rockdodger, not RocksnDiamonds which is a completely different game.

So tried Abes Amazing Adventure, https://github.com/OSSGames/AbesAmazingAdventure.
It uses configure so need to run "sh autogen.sh". Configure failed looking for SDL.h, patched the macro to look for SDL/SDL.h (source will need the same), reran autogen.sh and it dies here,
Code: [Select]
checking for sdl-config... h:/tmp/sdl/bin/sdl-config
checking for SDL - version >= 1.0.1... yes
checking for SDL_JoystickOpen... no
*** This version of SDL doesn't have joystick support.
*** Configuring without joystick support.
checking for Mix_OpenAudio in -lSDL_mixer... no
*** SDL_mixer not found.  Configuring without audio support.

I don't think any SDL1 has joystick support and the SDL_mixer error is,
Code: [Select]
configure:7448: checking for Mix_OpenAudio in -lSDL_mixer
configure:7477: eval gcc -o conftest.exe    conftest.c -lSDL_mixer    -ldl -lm -Lh:/tmp/SDL/lib -Zomf -lsdl12 &5
Error! E2028: _Mix_OpenAudio is an undefined reference

Of course the OW build has Mix_OpenAudio as a symbol, wrong calling convention.

Here's sdl-config, I put in h:\tmp\SDL\bin and did "set PATH=h:\tmp\SDL\bin;%PATH%
You need to adjust the prefix to reflect where you installed Valerie's SDL package, rename some of the libs as mentioned, and I had to patch h/SDL/SDL_config_os2.h like so,

With these changes to the SDL package, rockdodger compiles fine with the original makefile. Changes could still be made, EXENAME=rockdodger.exe so make clean cleans it and trying make pkg failed looking for /usr/bin/install, should be /@unixroot/usr/bin/install, like similar changes can be made.
Many a SDL game should compile for you with these.

Curious if they would work with GCC/LIBC as they're compiled with OpenWatcom. So did a quick hack to test. The original rockdodger failed to compile with an incomplete struct error and a lot of warnings, so I tested the newer one I referenced. It is a quick hack so the only changes I made to rockdodger was,

More work should be done on it, including install, uninstall and pkg.
Actually some of my changes can be reverted if Andrey's SDL package is adapted for GCC. Need sdl-config and renaming the lib names. eg sdlimage.lib --> SDL_image.lib. sdl-config would take care of setting -I and -L so the includes and libs can be found.
Anyways, here's the result, only tested to see if it runs and it needed sdl.ini, included in the package. Please test.

Found a newer rockdodger, its build dies due to no SDL-image. Readme also says SDL_mixer is a requirement.

In theory, recompiling should be easy. In practice, I randomly chose rockdodger. The compile died at,
Code: [Select]
H:\tmp\rockdodger>make
cc -c -g sound.c `sdl-config --cflags` -DVERSION=\"0.6\" -DCOMPILEDATE=\"28/7/02
\"
sound.c:5:10: fatal error: SDL/SDL_mixer.h: No such file or directory
    5 | #include <SDL/SDL_mixer.h>
      |          ^~~~~~~~~~~~~~~~~
compilation terminated.
make.exe: *** [Makefile:35: sound.o] Error 1

We don't have an RPM SDL_mixer and rockdodger uses mods for music.
I can build SDL_mixer, possible dependencies include, timidity for midi support, mikmod for mod support, smpeg or libmad-gpl for MP3 support, as well as flac and ogg which we have RPM's. Actually we also have libmikmod.
Seems there are SDL_mixer ports already floating around as well the other dependencies which can lead to DLL hell.
I also saw a SDL2 port, the repository was gone.

Virtualization / Re: Win-OS/2 - Open vbesvga.drv video driver
« on: June 22, 2025, 12:35:33 am »
One thing I discovered was that the X VESA driver failed on a UEFI install, to quote myself.
Code: [Select]
So out of curiosity, I tried opening a VESA xsession on a UEFI install. It failed, this seems to be the problem,
...
(EE) VESA(0): V_BIOS address 0x98000 out of range
...
On a BIOS install, it succeeds with,
...
(II) VESA(0): Primary V_BIOS segment is: 0xc000

Developer answered,

Code: [Select]
   BIOS at C000 can only be emulated in VDM. XFree86 definitely uses a
mini-VDM that lacks any functionality. "VGA BIOS" at 9xxx is an emulation
for system boot time and for panorama/gengradd.

So possibly the fact that the VGA BIOS is at a non-standard location on a UEFI install.

I also discovered that the changes that were made to SNAP broke the X VESA driver subtly, namely system hung when returning to the PM from X.
Another interesting discovery when reviewing the X source code was that X actually uses the SNAP code for its mini-VDM.

I tried these, nothing happened, possibly due to never having the Flash plugin installed here.
Bitwise simply wrapped the Win32 Flash plugin in an Odin wrapper so it is possible you have a Flash.exe or such installed somewhere.

Hi Martin, tried building it, make seems to get into a loop early on, one core at 100% and after a while the system locks up. Not sure how to proceed.

What about binary vs text? Often in C have to purposely set the pipe to binary, though for sending sending commands to a program it shouldn't matter.

Example 1: "SysFileTree" was unthinkable to me to use to find or search for files when I begun to try Rexx, the function should have been named SysSearchPath, SysFindFile or something along those lines, not "...Tree", totally bonkers name.

When sub-directories were first introduced, they were often described as a tree. The root (directory), branches or stems (sub-directories) and leaves (files). There were even commands such as deltree to delete multiple sub-directories in a branch.
