GP32 Mr.mirkos Sdk Replacement

[mr.mirko]

Hey,
When trying to compile the new zda tool i get an undefined reference to _compress.

Bobby

Mhh, works here...

make
gcc zda_compressor.c -o zda_compressor zlib/zlib.a -O2 -s
root:/opt/gp32-arm-elf/projecte/SDK/gp32_SDK/tool.zda_compressor#

please post the COMPLETE error...

How did you made the "sync" wait?
It seems to waits at 100Hz lcd rate the same time as at 50Hz <_<

No,

please check your real vsync rate.

short gp_initFramebuffer ( u32 addr, u16 bitmode, u16 refreshrate )
RETURNS
The real set Refreshrate.

Here is the complete error:

$ make

Here is the complete error:

$ make
gcc zda_compressor.c -o zda_compressor zlib/zlib.a  -O2 -s
/Temp/ccHlaOEe.o(.text+0x1ce):zda_compressor.c: undefined reference to `_compress'
collect2: ld returned 1 exit status
make: *** [all] Error 1

If youre on windows, you need to compile zlib again. The provided zlib.a in zlib
is compiled under linux.

So go to zlib
type make there too.

great work mirko )

you shoudl note somewhere that you can acces gp32 functions via cpp per

#include "cpp_prototypes.h"

and i've got a question: how can i use new / delete with your sdk?

and: can i use abstract classes/inheritance with your sdk?

 

[generalnmx]

Hmm, the MOD player included, can that only play Amiga Pro Tracker or also S3M, XM, and IT?

 

[no_skill]

if you want to use c++ with mrmirko's sdk you should check this thread.

i'm going to ask mr mirko if he could add a new c++ example to the sdk.

my topic

btw: what about chaning the api to something like this:

you have a new type

struct gpSurface{
int width;
int height;
u16 *pixeldata}

and let your bmp2bin converter spit out a gpSurface.

and then use functions like:

//blits the whole surface
void gp_blitFull(gpSurface dest, gpSurface target, int x, int y);
//blits a part of the surface
void gp_blitPart(gpSurface dest, gpSurface target, int x, int y, int sourcestartx, int sourcestarty, int sourceendx, int sourceendy);

//the same with a transparent color
void gp_blitFullTransparentColor(gpSurface dest, gpSurface target, int x, int y, u16 transpcolor);
void gp_blitPartTransparentColor(gpSurface dest, gpSurface target, int x, int y, int sourcestartx, int sourcestarty, int sourceendx, int sourceendy, u16 transpcolor);

//the same with an alpha value
void gp_blitFullAlpha(gpSurface dest, gpSurface target, int x, int y, int Alpha);
void gp_blitPartAlpha(gpSurface dest, gpSurface target, int x, int y, int sourcestartx, int sourcestarty, int sourceendx, int sourceendy, int Alpha);

advantages are:

• you don't have to remember w,h for every surface
• you can also blit parts of a surface (eg: for big tilesets where you want to blit a small part)

this is just a suggestions.

i think it would be far more convenient if the converter also stores the height and width of a surface and you're able to only blit a part of it.

Only 4 channel amiga mod files are supported.

c++ has nothing to do with the SDK, its a compiler issue.
You can use all c++ things you want..

yes, new/delete is supported by newlib.


If you run into some compile problems with your c++ project, try
a other crt0.S file. ( the one in the help dir )

 

[CrazyDesi]

Mirko could you please help me with this:

http://www.gp32x.de/board/index.php?showtopic=12530

 

[no_skill]

thanks. i'll try the other crt0.s

new/delete was really just a compiler issue. the c++ example isn't really a c++ example

have you got my new one? will you put it in the next release? (after i fully got c++ working (there's still a strange bug that may be caused by the crt0)

yes, there was a bug in my makefile, but it depends on what you want.
Plain c++, or a mixture of c and c++.
My example is more a mixture of c and c++,
yours is full c++, i update the Makefile to use the c++ as linker..

 

[no_skill]

i need full c++. (and i think that's what most c++ programmers want).

i wasn't able to use the other crt0s. (don't wanted to add the new mmu lib and the ads makefile is for ads aparently). only spent 5 minutes on that though.

but i have more imporant stuff todo atm anyway.

 

[Tharo]

Hm... Im not sure that this question makes reason but: Is your chatboard code nigel browns implementation of another one?

So everyone is yelling about the "nigel brown version" but i do not found another one now ...

The chatboard driver is a complete rewritten from spivvys original code.
I only use spivvys keymapping file.

Why you ask ?

 

[Tharo]

Hm because i would add script support in my engine the next week and think about it would be very smart to code the scripts while running the gp...

or generaly scripting support for some other stuff linke window guis and so on, too.

 

[Vimacs]

there isnt a " nigel brown chatboard version" all chatboards are the same (more or less)

 

[the_Diabologic]

i think, he ment the drivers :S
