[sdljava-users] Problems

[Nuno S. <dev...@im...>]

Hi, 

I did that. But the binaries i have are compiled for linux.

I need them compiled for osx (i think)

What i described was my problems in compiling sdljava for osx

MACKIE:~/Desktop/sdljava-0.9.1/src/sdljava/native lpx$ make
>gcc -o libsdljava.so SDLAudio_wrap.o SDLEvent_wrap.o SDLMain_wrap.o  
>SDLVideo_wrap.o SDLJoystick_wrap.o SDLCdrom_wrap.o -lSDL
>/usr/bin/ld: Undefined symbols:
>_main
>collect2: ld returned 1 exit status
>make: *** [libsdljava.so] Error 1
>
>I also had to take an option -shared because the compiler didnt have it.

>I have libsdl installed and the sdl libraries are in the place i

>--- /usr/lib/

About the other problems. Yes, in part. I finally realized that maybe 
some of my problems where in handling SDL.

I think that part of my problems are derived to Directfb, because it 
sometimes hangs when getting resources like keyboard and mouse.

Is there any other way of putting SDL working without using directfb?

Many thx

Greetings Nuno,

SDLJava has not yet officially worked on OSX.  However regardless I 
think it should work but I don't have an OSX machine to verify this myself.

The error you are getting, java.lang.UnsatisfiedLinkError, is because 
the virtual machine cannot find the library.  You need to pass the 
location of the SDLJava shared library as a -D switch.

$ java -Djava.library.path=<SOME_PATH>

Give that a shot and let me know if it works!

BTW:  Did you ever resolve your earlier problems??
