@walkero

sdl2/3benchmark is a simple tool to test SDL_Renderer subsystem, so this probably doesn't help if LiteXL is using frame buffer drawing.

Here are the links:

https://github.com/AmigaPorts/SDL/blob/SDL2/test/sdl2benchmark.c
https://github.com/AmigaPorts/SDL/blob/main/test/sdl3benchmark.c

Binaries should be in SDL2/3 release archives.

Yes, I just tested with sdl3benchmark, BUT, you need to enable profiling first. It's not very hard:

1) Read Profyler guide, it's awesome.
2) Build libprofyle.a and copy to SDK:local/newlib/lib/
3) Build SDL3 with -finstrument-functions added in Makefile.amigaos4
4) Build your app with -finstrument-functions and add -lprofyle
5) Start Profyler
6) Start your app
7) Quit your app
8) If you did 3), then it might take some time to get the results.

If you can't or don't want to do step 3, then I can provide you the libs later.

Debug variant has only serial debug added. Please use the non-debug lib for profiling to avoid logging overhead. Both libraries contain debug symbols.

CatComp vs. FlexCat: okay I will investigate this at some point.

With or without LITE_USE_SDL_RENDERER? If with LITE_USE_SDL_RENDERER, then does SDL_RENDER_DRIVER have impact?

It's a broad question. Did you have some specific subsystem / feature in mind?

@smarkusg

Good to hear it built OK.

Q: we can use LTO now? Which version of compiler is needed?

Just can't stay away

In case someone is interested to build MilkyTracker, here is a very rough guide. I have compiled some older versions natively using CMake, but since I don't have that on my current setup, I have been cross-compiling on Linux.

You need:

1) a working cross-compiler installation (adtools)
2) SDL2 headers + libs
3) git clone of https://github.com/capehill/MilkyTracker

Then you could create a build directory for cmake and configure project:

CMAKE_PREFIX_PATH=<your_path>/native-build/root-cross/ppc-amigaos/SDK/local/newlib cmake .. -DCMAKE_CROSSCOMPILING=ON -DCMAKE_FIND_ROOT_PATH=<your_path>/native-build/root-cross/bin/ -DCMAKE_CXX_COMPILER=ppc-amigaos-g++ -DCMAKE_C_COMPILER=ppc-amigaos-gcc -DFORCESDL=1 -DAMIGA=1 -DCMAKE_BUILD_TYPE=Release

If this worked, you can build it:

make -j8 VERBOSE=1

Oh, and some ideas what Nova could do:

- a GPU synth
- Real-time image processing with shader plugins
- a ray marched game (so not polygon-based). On my bucket list.

Totally possible. Need to add some license.

Nova sources are rare. I asked once GitHub copilot to generate code that creates fragment shader using Warp3D Nova. It came up with something distantly familiar but not quite right. Wonder how it got even that far.

@rjd324

I haven't yet tried with Q3 but it worked with my test program.

By the way, if you use that old SDL2 and do "setenv SDL_MOUSE_RELATIVE_CURSOR_VISIBLE 1", you should be able to see if relative mode works at all. Probably not, because of missing implementation. (And please remember to delete variable later)

@FlynnTheAvatar

I suppose you mean the A500 emulator. Is it open source? I heard about that today so I can't say much.

@afxgroup

I'm planning to use this with some of my own software if I ever find time to work on those :/

@jabirulo

Yes, need to investigate is it SDL3 or ImGui issue.

@rjd324

Cool. I have tried Spacecadet but didn't realize that at time. Does it use OpenGL context or SDL_renderer backend? I noticed ImGui's SDL_Renderer uses geometry calls which cannot be properly implemented with CompositeTags due to missing vertex colors. Of course software, OpenGL or OpenGLES2 work with SDL_renderer too.

Dear ImGui

Posted on: 3/1 8:13 #17

Just can't stay away

https://github.com/ocornut/imgui

Here is a rough guide how to get it running using SDL2 or 3.

* Common

imconfig.h:

To fix colors, add:

#define IM_COL32_R_SHIFT 24
#define IM_COL32_G_SHIFT 16
#define IM_COL32_B_SHIFT 8
#define IM_COL32_A_SHIFT 0
#define IM_COL32_A_MASK 0x000000FF

Enable following to avoid code which uses fork():

#define IMGUI_DISABLE_DEFAULT_SHELL_FUNCTIONS

* MiniGL (example_sdl2_opengl2)

main.cpp:

Modify GL version to supported:

SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 1);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 3);

* OpenGLES 2 (example_sdl2_opengl3, example_sdl3_opengl3)

Makefile:

Add:

-DIMGUI_IMPL_OPENGL_ES2

Demo: https://capehill.kapsi.fi/imgui/imgui_amigaos4.lha (MiniGL or OpenGLES2 required).

I wonder if there is a chance to get some Nova fixes and features? For example float texture and cube map texture. And then those missing ops that fails shader compilation.
