[games] DXX-Rebirth - frustrations

[Hasturtium]

So I'm trying to build DXX-Rebirth on Fedora 37, following the official directions posted here, and using the build instructions

Code: [Select]

scons 'CXXFLAGS=-O3 -mcpu=power9 -DNO_WARN_X86_INTRINSICS' 'CPPFLAGS=-O3 -mcpu=power9 -DNO_WARN_X86_INTRINSICS' opengl=1yields this error terminating compilation:

Code: [Select]

scons: *** Rebirth configured with OpenGL enabled, but SDL configured with OpenGL disabled.  Disable Rebirth OpenGL or install an SDL with OpenGL enabled.  See build/sconf.log for details.  Stop.I've tried a few Google searches but nothing conclusively indicates what I should do to configure or replace SDL2. I have not built it from source or installed it from alternative repos - this is stock Fedora.

Here is someone with a similar issue:

I have not looked at it in detail.

I installed d1x-rebirth and d2x-rebirth out of the Fedora repos and those worked fine. Any particular reason you want to build them?

Honestly, I didn't assume a package would be available, so I didn't look. But now I can't find a package by the name of dxx-rebirth, d1x-rebirth, or d2x-rebirth for F37.

edit: After various travails, determined the package names are literally "d1x" and "d2x." Well, at least that fixes things up. Now to test...
edit the second: Well, it's working. MIDI could sound better, but I'm an old OPLhead. What's the best solution for pointing the executable to the registered version - should I overwrite the contents of the demo files provided with the packages, or add a path entry to the dxx ini?

Good, you found it (for others curious - RPMFusion).

As far as the registered files:

Code: [Select]

% ls /usr/share/d1x
d1shar  d1x-rebirth.bmp  full
% ls /usr/share/d2x
d2shar  d2x-rebirth.bmp  full
% ls /usr/share/d1x/full

% ls /usr/share/d2x/full

/usr/bin/d[12]x-rebirth are shell scripts. If they find the registered files present, they will start the registered version, otherwise shareware. No config files required.
