Alternative SDL port as static library

[aquadran]

It's updated to newer version of SDL library.
It also has fixes to some bugs in original port.
Support for mouse and keyboard is added after load kernel modules for usb hid, events and also created device nodes at /dev/event0 ... 31

Changelog:

v0.03 - included missing sdl-config in package
v0.02 - enabled 8, 15, 16, 24 video support by internal sdl emulation buffer

Many thanks

[aquadran]

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

Hi,

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.

[aquadran]

Updated SDL library for support modes other than native 32 bit. It support now 8,15,16,24 now.

Hi,

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 :

Code: Select all

#!/bin/sh
CPP=arm-linux-gnueabi-gcc
INCL=/opt/arm-linux-gnueabi/arm-linux-gnueabi/include
LIBS=`./sdl-config --libs`
SDLI=`./sdl-config --cflags`

echo "$CPP  $SDLI -c main.c "
$CPP $SDLI -c main.c 
echo "$CPP -o main.so -fpic -L$LIBS -lSDL main.o"
$CPP -static -o main.so -fpic -L$LIBS  -l SDL main.o

the error is during link :

Code: Select all

arm-linux-gnueabi-gcc -o main.so -fpic -L/opt/arm-linux-gnueabi/arm-linux-gnueabi/lib/libSDL.a -lpthread -lSDL main.o
/mnt/new_home/opt/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/4.2.0/../../../../arm-linux-gnueabi/lib/crt1.o: In function `_start':
....

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

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)
