It fails to build for me.
I'm building with OpenGlide...

Any ideas?

See Tutorial: dosbox with Glide under Linux for building on Linux.

Patch updated for recent DOSBox SVN.

Great news ! 😀
I never managed to get it working 🙁

A quick question about OpenGlide: What exactly is it required for? Is it used as default wrapper for gulikozas patch? Is any external DLL still required or can other wrappers like nGlide or dgVooDoo2 be used as well?

OpenGlide is a Glide wrapper that emulates Glide2x 2.4 APIs similar to dgVoodoos and nGlide. Yes, you can replace it with dgVoodoos or nGlide. There is no so-called default wrapper for Glide pass-through, it just loads the 1st instance of Glide2x DLL in the search path. OpenGlide plays a significant role for development because it is open-sourced, based on OpenGL technology which makes it portable to any systems with OpenGL. Its Glide emulation is not stellar by today's standard, which has been greatly surpassed by dgVoodoos and nGlide, and has not been maintained for years. I believe it is the only Glide emulation solution for Linux and MacOS (from MacGlide a fork of OpenGlide) today. We shall see if nGlide with Vulkan backend will make a break-through for non-Windows system, especially Linux.

I do hope to see zeckensack's GlideWrapper will still be around and he would be able to open source it to help Linux to catch up with Windows on Glide emulation. I have been trying to contact him but so far to no avail.

I think the dosbox.conf descriptions should be this way:

# voodoo: Enable VOODOO emulation.

# glide: Enable glide pass-through to external wrappers (eg. nGlide, dgVoodoo 2): true,false.

And glide enabled as default as both can be enabled at the same time right now.

this removes kekko's GL patch right? you can get either kekko's software, or the glide wrapper one with GL.
For my fork the wrapper approach doesn't work. Any way you can let me know how to fix vanilla gekko's patch?

No. It's called 2-in-1, so both kekko's voodoo chip emulation and gulikoza's Glide pass-through are included and both can be active at the same time in single build.

I mean the hardware rendererd variant of kekko's, maybe I misapplied it, I'll try again, thanks!

@kjliew could you please rebase the patch on top of the latest dosbox svn?
It doesn't apply any longer..

Hello, I would like to use this patch but it does not applied on latest dosbox svn 4482.
Is there a more recent patch version?
