>sadly it means that serial debugs are not in sync with the freeze

This is some code that I use in GMAP to output debug to the screen bitmap. So there is no serial debugs or printf latency

It will need some adaptation but the idea is here


also adding some LL macros at beginning of litigious lines may help

#define LL {Libprintf("Line:%ld \n",(LONG)__LINE__);}




/*=================================================================*/
ULONG lastline=0;
struct GM_Game *GlobalG;
/*=================================================================*/
#ifdef OS3
#ifdef DOSCREENDEBUG

void OS_DrawText3(struct GM_Game *G,UBYTE *text)
{
struct OS_Screen *S;
struct RastPort *rp;
WORD x,y;

CHECK(text)
CHECK(G)
S=G->screen;
CHECK(S)
rp=S->drawrastport;
CHECK(rp)
x=S->T->rect.w/2; y=lastline;

if(lastline > (S->T->rect.h-10))
lastline=0;
lastline=lastline+10;

SetAPen(rp, 240) ;
RectFill(rp,x,y,S->T->rect.w,y+20);
SetAPen(rp, 241) ;
Move(rp,x,y);
Text(rp,(void*)text, strlen(text));
}
/*==================================================================================*/
#define PUTCHARFUNC (void (*))"\x16\xc0\x4e\x75"
void Libprintf(void *string,...)
{
va_list args;
UBYTE buffer[4096];

if(SysBase==0) return;
if(strlen(string)>1024)
return;

va_start(args, string);
RawDoFmt(string, args, PUTCHARFUNC, buffer);
va_end(args);

if(strlen(buffer)<1024)

It seems you are right about the interferance of the serial/debug outputs.

Furthermore it now stops at 675, wasn't able to get it to 680 (five tests)

I need to review all debug prints in SDL2 one day. Meanwhile, I tried a simple test that did something like:

#include proto/exec.h

int main(void)
{
int i;
for (i = 0; i < 100000; i++)
{
IExec->DebugPrintF("Debugging %d\n", i);
}
return 0;
}

Can you try it, too? Fix the include line :) Above test works for me.

Just a question from a noob

Why is it
IDOS->Printf
but
IExec->DebugPrintF

Shouldn't they be consistant?

printf( const char *fmt, ..)

Is the C standard.

Printf( const char *fmt, … )

is dos.library version, but is not compatible, with C standard, %d is short, while C standard %d is int.
when using int on Printf you need to use %ld.

DebugPrintF

I agree this is mistake to use "F" at the end, it means that you have add "Debug" and change "f" to "F" when your coding.
anyway I think DebugPrintF is following the more modern standard of printf, not Printf, but I have to check docs.

2.0.8 RC2 can be tested: https://github.com/AmigaPorts/SDL/releases

Important: default libraries don't contain debug prints anymore.

In order to see serial logs, replace SOBJS:libSDL2-2.0.so with its debug version, or in static linking scenario, link with -lSDL2_debug.

Not sure if this fits, but as it's using SDL/OpenGL i'm trying.

I have a port which i want to make work at 100%.
Right now 75% are done, missing only the OpenGL part.

This, however, compiles fine, but crashes on start.
Reason is, that an OpenGL extension is used (and available, at least in our SDK), but refuses to work from the binary.

The extenstion is GL_ARB's framebuffer and texture, added to the code with GL_GLEXT_PROTOTYPES

#include <SDL.h>
#define GL_GLEXT_PROTOTYPES
#include <SDL_opengl.h>
#include <math.h>
#include <vector>
#include "graphics.h"
#include "util.h"
#include "systemstub.h"


It's used there in the code.
This function errors out on start, right before it crashes after opening the window.

void GraphicsGL::init(int targetWint targetH) {
    
Graphics::init(targetWtargetH);
    
glBlendFunc(GL_SRC_ALPHAGL_ONE_MINUS_SRC_ALPHA);
    
glEnable(GL_BLEND);
    
glDisable(GL_DEPTH_TEST);
    
glShadeModel(GL_SMOOTH);
    const 
char *exts = (const char *)glGetString(GL_EXTENSIONS);
    const 
bool npotTex hasExtension(exts"GL_ARB_texture_non_power_of_two");
    const 
bool hasFbo hasExtension(exts"GL_ARB_framebuffer_object");
    
_backgroundTex.init();
    
_backgroundTex._npotTex npotTex;
    
_fontTex.init();
    
_fontTex._npotTex npotTex;
    
_spritesTex.init();
    
_spritesTex._npotTex npotTex;
    if (
hasFbo) {
        
setupFboFuncs();
        const 
bool err initFbo();
        if (
err) {
            
_fptr.glBindFramebuffer(GL_FRAMEBUFFER0);
        }
    } else { 
// AmigaOS 4 debug
        
error("No GL_ARB_framebuffer_object"); // AmigaOS4 debug
    
}
}


Do i have to do it differently on AmigaOS4, or are these extensions available in the SDK, but not in the gfx/3D driver?

Any help welcome

Somewhere in clearBuf with ABADCAFE in r2, but I can't check right now.

So FBO are a no-no?

Not with current MiniGL. OpenGL ES 2.0 should support FBOs: https://www.khronos.org/registry/OpenGL-Refpages/es2.0/

Regarding MiniGL:

http://www.hyperion-entertainment.biz ... s/updates-kc/src/others.c

You can query the available extensions with glGetString(GL_EXTENSIONS). It seems that your example is already doing something like that.

Does your example absolutely require the FBOs? If not, then it should be figured out why the crash happens.

Damn, so still waiting for the driver

It's possible to comment the FBO stuff out, but I would lose some functionality/support for some stuff.

Thank you for the hints

If you cant use a FBO as buffer then you cant clear it = normal.

>Damn, so still waiting for the driver

A workaround may (??) be to render in another RGB bitmap then convert this bitmap to the texture

glTexImage2D(GL_TEXTURE_2D, 0, 3, w, h, 0,GL_RGB,GL_UNSIGNED_BYTE, bitmaptr);

1) I dont know if MiniGL support changing the (rendering buffer) bitmap on the fly
2) Depending on what you render in your FBO(=bitmap) it may not works (z depth)

You can't change buffers without FBOs unfortunately, and no Warp3D driver supports that. Only the old ways work, i.e. rendering whatever you need for your "framebuffer" first, and then creating a texture from it with glGetTexImage, which you can overlay your scene with.

This is just like television, only you can see much further.
