[gentoo-embedded] SDL library usage

[gentoo-embedded] SDL library usage

[Jakub Ladman]

Greetings

My friend has recomended me SDL library for graphical output of my SuperH4 
embedded system with framebuffer device.

After succesfull cross emerge the media-libs/libsdl library, i am trying to 
crosscompile any demo, but everythings fails.

Do you have tip to a crosscompilable test software for graphics via sdl?

Here is output of running Makefile, where i have manually changed gcc compiler 
to sh4-pc-linux-uclibc.

ladmanj@trotl ~/src/fire_sh $ make
sh4-pc-linux-uclibc-gcc -DPACKAGE=\"fire\" -DVERSION=\"1.0\"  -I. -I.      -g -O2 -I/usr/include/SDL -D_REENTRANT -c 
fire.c
sh4-pc-linux-uclibc-gcc  -g -O2 -I/usr/include/SDL -D_REENTRANT  -o fire  
fire.o  -lSDL -lpthread
/usr/lib/gcc/sh4-pc-linux-uclibc/3.4.6/../../../../sh4-pc-linux-uclibc/bin/ld: 
cannot find -lSDL
collect2: ld returned 1 exit status
make: *** [fire] Error 1
ladmanj@trotl ~/src/fire_sh $                


It seems, like the cross compiler does not know the native library.


Thanks for your help
Best regards

Try including and linking with the sdl in your ROOT environment vs
your / env. You know the -L/path -I/path flags..

solar told you how already ... the -I paths in your output are clearly wrong 
and you need to add custom -L paths to your LDFLAGS so the build can find the 
libsdl you cross compiled

I can not found the right path.
I have found both header SDL.h and binary libSDL.so files with locate in the 
target directory, but if i have copied the paths to -l and -L parameters, 
linker still tells me, that it can not be found.

Sorry i am a newbie and have not enough knowledge for a effective 
troubleshooting.

Thank you
