[Buildroot] [Fwd: Re: SDL_image, SDL_ttf & Co (libpng12.So bug)]

[Claudio Leonel]

Hi,

I was using buildroot version 20061111 and managed to
compile SDL_image including the following flags (LDFLAGS) for the
linker.

$(SDL_IMAGE_DIR)/.compiled: $(SDL_IMAGE_DIR)/.configured
	$(MAKE) LDFLAGS=$(STAGING_DIR)/lib/libpng12.so -C $(SDL_IMAGE_DIR)
	touch $(SDL_IMAGE_DIR)/.compiled

I checked the dependencies of the generated libSDL_image.so
file and it seemed OK, but I haven't tested it yet in
the target.


But then I changed to a newer buildroot version: 20061124
and the previous modification was not enough, other linker
errors appeared, regarding the host directfb library.

I had to change the sdl.mk for SDL adding the following line
to configure:
	--disable-video-directfb

(I am not using directfb, only the framebuffer)


I am now having problems compiling SDL_ttf ...


Regards,

Well I investigate a little too and find that when removing "showimage" example
compilation from Makefile, then I was able to compile SDL_image. (The error on
libpng12.so is during showimage tool link.) But if think your solution is
cleaner

ok ,thanks for the tip !

I had problems too :-). I suppose you have the same: missing OpenGL library.
I was able to compile SDL_ttf (2.0.8) when adding the following options to
configure:
        --disable-sdltest
	--without-x
	--disable-opengl

I attach my SDL_ttf makefile if it can help you. Let me know if it solves your
problem !

regards,
Julien

Hi,

Thanks, using this flags in configure, SDL_ttf
compiled OK !

Hi,

I have tried your "trick" for SDL_image compilation and even if I put the
LDFLAGS you advised I always have the same link error (/usr/lib/libpng12.so pb)

Are you sure it was the only thing you changed ?

Thanks,
Julien
