FPC4GP2X status?

[dmantione]

Can you please double check? THREADVARLIST_GP2X_SDL_MIXER is a symbol generated by FPC, GCC does not generate such a symbol. As there are no variables or non-external procedures in your Pascal unit, this is exactly the output you would expect when you use nm on the FPC generated .o file.

Ok, I will double check...

Hi dmantione, I don't know what happened before, but I am now getting a difference output when I run the nm on the .o file (I am now using the -a option as well):

c:\lazarus\Projects\sdl libs test>arm-linux-nm.exe -a gp2xlibs\gp2x_sdl_mixer.o

does this help?

I think I know what happened Reading back I read yout unit is called gp2x_sdl_mixer.pas. That means FPC is writing a file gp2x_sdl_mixer.o. In your post you write the file generated by gcc is gp2x_sdl_mixer.o.

You start to see where this is going?

Yup, we have a name clash, FPC is either overwriting the file generated by GCC or (in case they are in differend directories) finds the file it generated itself when processing the {$l gp2x_sdl_mixer.o}

hehe, ok...I should try renaming either the gp2x_sdl_mixer.c or the gp2x_sdl_mixer.pas files and try again :-)

I will let you know how it goes!

Thanks,
Paul

That was the problem!!

I renamed the gp2x_sdl_mixer.c to gp2x_sdl_mixer_c.c

Now I get an error about undefined references

[code]
C:\devkitGP2X\lib\\libmikmod.a(mdriver.o&# 41;: In function `MD_DropPrivileges':
../playercode/mdriver.c:919: warning: Using 'getpwnam' in statically ]

Could I be missing a lib or have something in the wrong order in the linking section?

arm-linux-ld.exe  -static --no-warn-mismatch --reduce-memory-overheads --gc-sections -s -L. -o%1.gpe link.res -lpng -lm -lstdc++ -lgcc_eh -lpthread -lvorbisidec -lSDL_mixer -lmikmod -smpeg -lpng12 -lz -lSDL -ljpeg -lfreetype -lc -lgcc

At least I am getting somewhere!

cheers,
Paul

Hi Paul, it looks like you are missing both smpeg ( libsmpeg ) for mp3 playback you choice are either remove the reference to smpeg or statically link smpeg into libSDL_mixer. The latter is what the Mac OS X guys did so that libSDL_Mixer supports everything out of the box. You may have to build smpeg from source.

[quote="savage"]Hi Paul, it looks like you are missing both smpeg ( libsmpeg ) for mp3 playback you choice are either remove the reference to smpeg or statically ]

ok...

If it helps, I do have these files:

C:\devkitGP2X\bin\smpeg-config
C:\devkitGP2X\include\smpeg\smpeg.h
C:\devkitGP2X\lib\libsmpeg.a
C:\devkitGP2X\lib\libsmpeg.la
C:\devkitGP2X\share\aclocal\smpeg.m4

PS If I did want to remove the reference to smpeg, what should I do?

cheers,
Paul.

[savage]

Could you try this command line...

arm-linux-ld.exe  -static --no-warn-mismatch --reduce-memory-overheads --gc-sections -s -L. -o%1.gpe link.res -lpng -lm -lstdc++ -lgcc_eh -lpthread -lvorbisidec -lSDL_mixer -lmikmod -lsmpeg -lpng12 -lz -lSDL -ljpeg -lfreetype -lc -lgcc

you seemed to be missing the

-l

in front of the

smpeg

in the one you posted.

If you can I would leave it in, because loads of people need mp3 support.

I tried that, but I still get these errors:
