Bugzilla Bug 211137

If you compile libsdl with libcaca USE flag on, it does not include libcaca
support.

There are multiple bugs here. If you make an objdump before stripping, you see
the some of the Caca symbols. But there is already a bug. In SDL_video.c, it
tries to use CACA_bootstrap, though in SDL_cacavideo.c, Caca_bootstrap is
defined.

This can be fixed by changing the libsdl-1.2.11-libcaca*.patch and writing
CACA_bootstrap there.

The other problem is, that SDL_VIDEO_DRIVER_CACA is never defined in the end.
It takes a while until I figured out the problem:

It is not defined, because it never occurs in include/SDL_config.h.in and
therefore the configure.in doesn't add it.

You can fix it by just adding an "#undef .." to include/SDL_config.h.in before
you run the econf. I did it:

    if use libcaca ; then
        sed -i -e "s/#endif \/\* _SDL_config_h \*\///" include/SDL_config.h.in
        echo "#undef SDL_VIDEO_DRIVER_CACA" >> include/SDL_config.h.in
        echo "#endif" >> include/SDL_config.h.in
    fi

Now it compiles correctly with libcaca support.

Btw., same problem with 1.2.11.

Reopen with complete emerge log and emerge --info output; thanks.

This bug has absolute nothing to do with my system, it's completly
system/hardware independent.

But here it is:

And which part of the emerge log do you want to have? And of the fixed version
or the unfixed version? Whereby there is no visible difference.

In the configure part, you see that configure checks for libcaca support and
includes it. I checked that also by modifing the configure.in, it gets in all
cases to the line with AC_DEFINE(SDL_VIDEO_DRIVER_CACA).

The *whole* thing; thanks.

Created an attachment (id=144391) [details]
log of libSDL 1.2.11

Created an attachment (id=144392) [details]
log of libSDL 1.2.13

To the logs:
libSDL 1.2.11 is without my fix, libSDL 1.2.13 is with my fix

hrm, libsdl used to use autoheader, so the SDL_config.h stuff would be taken
care of for us

ive added both your fixes to 1.2.13, thanks for debugging
