[_MakeFile_]

Has anyone tried to compile the game SuperTux? I have tried several times with no luck. Here is the source code for the game.

You have to have PSPSDK and SDL_Mixer installed in your Cygwin enviroment and SDL package installed as well which I do all. These are the errors I am getting when compiling the game...

Can anyone help? I would really appriciate it. Thanks

are you linking against libogg or libtremor or whichever library provides t ogg decoding?

I am linking against libtremor because that is the default lib that SDL_Mixer uses when compiling the SDL_Mixer library. This is the configuration I used when compiling SDL_Mixer
LDFLAGS="-L`psp-config --pspsdk-path`/lib -lc -lpspuser" \
./configure --host psp --with-sdl-prefix=`psp-config --psp-prefix` \
--disable-music-mp3 --prefix=`psp-config --psp-prefix`
Should I change something?
Thanks

Seems to me that the sdl code cant find the ogg decoder.
Perhaps the link order in the makefile is incorrect? I dont have specific experience with sdl...

Perhaps. I will try to look over the makefile and maybe recompile my librabries again. Thanks for replying.

[cheriff]

I was actually leaning more to how you are compiling the app, all libs *should* be fine.

Is -ltremor before -lsdl in the makefile for your application?
Even tho you compiled sdl against tremor, I dont know if the actual code was pulled in (looks like no) so you'd need to link tremor and sdl when building the game.

I am still not able to compile this game. I ahve been trying for a long time also. Here is what the make file says that is included in the source code. Maybe someone can try to compile this game and let me know how it went.

I appriciate any help. Thank you

Ok, well, like I said Im not sure on the exact details of linking and the ogg functions (ov_read, etc) may not have been pulled from libtremor into libsdl when you build that. Maybe it should, maybe it had, i don't know but thats how it looks to me.

I tried changing that also in my makefile. I still get the same errors. I think the errors are coming from my SDL_Mixer folder when I complied it in my trunk. I am going to try to redownload the SDL_Mixer folder from subversion again and recompile everything all over again and see if that helps. I posted the source code link for the game Supertux that I am trying to compile so that if anyone wants to try to compile it and see if they can compile it with no errors, let me know. Thanks

I solved the problem. SDL_mixer has to be linked to lib vorbis. It finally now compiles. I also fixed this problem with abrick from the pspware repository. Before abrick could not be compiled because SDL_mixer wasn't linked right. I uploaded a new makefile for abrick to svn and now you all should be able to compile abrick and play it on your psp. Thanks for your help cheriff
