I hope more people will start making port of other SDL programs :)

Thanks for the lib ... I restart my test using this lib ...
do yuo have any information about the usage of SDL_ttf, do you know if it's possible to get them ?

thanks again.

Philippe.
SDL_ttf not exist tv, but why not compiling and use it :)
TV has SDL_mixer and SDL_image shared library and could be reused, or as with SDL compiling recent from sources and use as static library.

Regarding this port of SDL, I'm planning add internal gfx buffer to emulate video modes other 32 bit.

I am confused, because I try to link my prog (that run previously with shared lib) with static lib ... and fall in error

I use to compile & link this shell :

Can you help me .. I do lot of try and now ...I think it's a big mistake but I don't see it ??? :?: :oops: :oops:

seems linker missing the information that you want to build a shared object file an it try to link an executable for you (without a main function)

try:

Code: Select all

arm-linux-gnueabi-gcc `./sdl-config --cflags --libs` -fPIC -shared -o main.so main.c /opt/arm-linux-gnueabi/arm-linux-gnueabi/lib/libSDL.a
but first fix your sdl-config to give just the correct pathes and no libs back (than you have better control what to link where)
like:

Code: Select all

/sdl-config --cflags --libs
-I/home/Video-HD/Chelsea.gnueabi/build/tmp/staging/arm-linux-gnueabi/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT
-L/home/Video-HD/Chelsea.gnueabi/build/tmp/staging/arm-linux-gnueabi/lib -lpthread

actually it's better if --libs return like this:
/opt/arm-linux-gnueabi/arm-linux-gnueabi/lib/libSDL.a -lpthread

library which I uploaded has proper sdl-config, however after I split to binary and sources I forgot include into binary to prevent confusion.
I'll reupload it (done)
