Mlib V0.2 Sources Availabe..

mr.spiv · Apr 6, 2005

mlib v0.2 - a tiny alternative module player & SFX library for GP32 is now available for download. No bells and whistles, no any SDK dependency, fast, etc.. (and hopefully not too bugged). Check http://www.deadcoderssociety.org for the archive.

nice stuff.
now i just need to get it compiling. darn makefiles!

mr.spiv · Apr 6, 2005

Arr.. just noticed that the player.c file had mixer code selection forced to "C-version". So if you want to have asm mixer etc you need to edit the "ifdefs" in the file a bit. sowwy :blink:

It strongly interests me ^_^ I'll try to compile my shoot using this mod lib (I use ADS) =)

Is it any faster than CHN's one ?

Is it any faster than CHN's one ? smile.gif

I havent success to made a correct compilation with my GCC 3.4.1 ... I dont know why, but when I'll success , i'll made a little bench sure.
Today I think with ASM mixer this lib will be faster than CHN's.

What's the problem? I know that Makefiles might have "issues" on Winblow$ systems e.g.
I seem to use PWD environment variable, which should contain a full path to your current
working directoty. Or is it something else? :blink:

if you convert all those inline ASM chuncks to ADS convention, please send those to me also

i've put your 6 files:
gp32.h (i'm not sure if it's necesary or not)
player.c - main player code & mixer (portable)
player.h - structures etc
sound.c - GP32 specific direct hardware level DMA sound buffer
sound.h - structures etc for the above
asmfuncs.s - optional context switch code for "out of IRQ mixing"
in the same directory as my gpmain.c

this is the gpmain.c:

#include "gpdef.h"

Well thank to Mr Spiv on IRC to help me

Now it work !!!

Here my example (source,lib,makefile,fxe,gxb are included)
spiv_mod_example.zip

See you

Jycet also pointed out that at least effect 6xx bugs.. gonna fix it :blink:

Well, very nice news mlib v0.3 is out on Mr Spiv site !!

http://www.deadcoderssociety.tk/

I'll use it in the next days

Thank you Mr Spiv
