In the last time we did, in my opinion, a big mistake. In test scripts
we checked for libpng like: SDL::Config->has('png'). But this didnt
ever returned true, Simply because the HAVE_PNG was only set when
actually building that lib in SDL. (Note: not Alien::SDL)
This ->has() method works pretty fine for stuff like SDL_gfx, since it
will return true if we found SDL_gfx*.h. But there was no check for
png.h at this stage. So even if we found libpng in system dirs or when
we build it on our own, ->has('png') never returned true.
I changed the tests so it checks now for libpng in the shlib-hash that
we get from Alien::SDL. This hash contains all found/build libs, and
And why does it fail then?
BSD. LibPNG needs libz to run. Normally you would think that libpng is
actually linked against libz, but hey, the BSD ppl dont think that
way. I dont know the reasons but they decided to somehow build libpng
without linking against libz.
when you do: ldd /path/to/libpng.so you will get all the dependencies
printed as a list. This works pretty fine on most systems, like on our
ubuntu's and what not.
On OpemBSD it prints an error message that the lib cant be loaded. But
if you do LD_PRELOAD_LIBS=/path/to/libz.so ldd /path/to/libpng.so it
will work. So we have to preload the lib in order libpng will use it.
Doing this needs to happen on a very early level. Doing it from within
a running perl is to late, even if we load libpng using DynaLoader.
The only thing I can think about atm is that we run a perl, load that
libz.so, and start a child perl process that does the stuff we do now.
This problem applies to libpng (needs libz), libtiff (needs libjpeg)
and libvorbis (needs libogg).
Before YAPC::EU I was working hard on that thing, I guess I can supply
a patch in a few days.
Another problem that exists right now is that the old G4-Macs dont
have a header file we want to use, I will debug that at some point. I
dont think that there are so many users with a G4. These fails only
come from BinGOs so far.
And there are still SDL::Controller(::Interface) fails. But since I
dont really understand whats happening there it would be cool if the
author (you kathekore ;o) would have a look at it.
So far from me, I will write a msg about the YAPC later.
See ya and take care,

I think the problem is TIFF support on BSD and Solaris, but FROGGS will
know for sure.

It looks like SDL lastest experimental has quite a few bit of fails. May I
get a summary of what the fails are?
