I'm trying to port a library to psp, and I'm getting this error (config.log):

[Wally]

I got a gut feeling you'll have to link more libraries than that.

[fungos]

Ok, I found where I was defining that two libraries (lol, my psplibraries own build script....)

I added more libraries until I got stuck here:

[Wally]

odd :/ I cant find them either.. Maybe its an external library.. One of the more experienced members will have to help you..

[jimparis]

Add another "-lc" at the front of the libraries. g++ moves the first one and messes up the order. See http://forums.ps2dev.org/viewtopic.php?p=34441#34441

Thanks jimparis, I read all threads about that issue, but I still having some problem with this.

The two -lc worked, but now I still get some errors.

these are the current errors, and again, I can only find these calls on pspuser and pspkernel.

[jimparis]

-Wl,--start-group would also work. It is just a linker ordering issue (all dependences must come after the functions that use them) and exceptions probably adds more libraries to the end.

[fungos]

I found a good topic about this problem, and you was explaining the problems with this in psptoolchain. Thank you for your help! I get the configure to work, now I'm fixing other minor problems.

[fungos]

Well, the things are each time worse. The library that I'm trying to port is called guichan (take a look at it http://guichan.sourceforge.net/), its a very good GUI framework that uses SDL and/or OpenGL.

After being able to compile the library, I was trying to get it sample program running, but as expected, It failed.

Anyway, my current problem is very weird, I never saw error messages like these .rodata and vtable errors.

[jimparis]

The first error (undefined SDL_main) is because you need to put the main() function inside an 'extern "C" {}' block, search other threads for more discussion on SDL and C++.

The other undefined references are probably because you're missing some library or object file where those symbols are defined (gcn::KeyEvent::GetKey, etc).

[fungos]

Thanks again, you're being very nice and helpful :)

Now, what I think is the last problem:


When linking without -lSDL_mixer:

[Jim]

Either you need to download and port SMPEG library, or you need to configure guichan or SDL or whatever depends on it not to need it.

Ok, I'm getting this problem because I'm trying to play .WAV files? Nobody never had this problem with SMPEG when using SDL_mixer?

Anyway, I ported SMPEG (I stripped out the video code) and now I reduced the errors to multiple definitions... look here:

[Jim]

Whether or not to use SMPEG is a configuration option for SDL_mixer - I assume everyone else turns it off.
Not sure how you fix the latest problem though. Try commenting one of them out (most likely the one in music.c), or try to work out how come the mikmod (module player) part of SDL_mixer is defining the same things as music.c.

Anyway, I gave up to get guichan FF demo working with sound. I ported SMPEG and guichan. Both working on PSP (how can I commit it?).

Btw, about SDL_mixer using SMPEG (I used psplibraries to install SDL_mixer and others), I can't tell if I can disable it, I tried to see tis ./configure parameters, but It doesn't have an explicit --disable-smpeg. just one: --enable-music-mp3 (default=yes) that uses smpeg. If I disable that, how can I get mp3 played? mikmod does that?

Ok, about guichan, It's working awesome. But guichan OpenGL support doesn't work because pspgl haven't all needed functions. Anybody knows if anyone still developing pspgl?

As I said, I tested guichan FF demo on PSP, but I haven't fixed to use Joystick yet :D But looks very nice! Soon I will do it work with Joystick and put the 1.50 sample somewhere for download (btw, look my other thread about SDL and 3.xx).

Well, I'm preparing psplibraries scripts for SMPEG and guichan, so everyone can use these libs too.

Thanks again everyone that read this thread and who helped me.

EDIT:
Well, just need rebuild SDL_mixer with ./configure --enable-music-mp3=no .. But, as I already ported SMPEG. This is not necessary.

About the multiple definition.. I fixed that. music.c redefined that two functions, I think it was a macro error. there was a ifdef looking if mikmod was used then It compile that code, the correct I think, should be ifndef. I corrected and looks right now.

Someone with svn access should fix that too. Just change the #ifdef in line music.c:1156 to #ifndef.

I'm having SDL_mixer problems myself, but not on the compilation.

I cimply followed the instruction on the readme.psp and everything worked fine.

The problem i'm having is that i get no music. Even more strange is that i get sound (Mix_Chunk). the sound works perfectly. And the Music aswell, but only when compiling on Windows. When i port it to PSP, everything works as normal but i hear no sound.

I get no errors to paste and no crashes. I even "copyed" the code from the rRootage psp port, but still nuthing.

i had already tryed both .ogg and .mp3.

This is kinda frustrating :|

i'm running on a Slim with eLoader 1.0
