BerryBots pre-release testing help

Versions after libpng12 broke compatability with libpng12 in notable ways. For this reason, libpng12 still has maintnance release, and many distributions (i.e. Arch Linux, Ubuntu, Debian, and after checking, Fedora 18 too) have pakages for both libpng12 and the newst version of libpng, which can be installed simuntaneously without conflict.

AW: You should be able to install a "libpng12" package from your package manager I believe.

I have no attachment to any libpng versions, so I guess the best move is to compile against whichever version works most commonly across default installs of Ubuntu / Mageia / Fedora, probably libpng14. Is that what you'd recommend?

No clue about Mageia, but Fedora and Arch provide both libpng15 and libpng12 (libpng12 isn't installed by default, but should be easy to install). Ubuntu and Debian however only provide libpng12. To me libpng12 looks like the safest for binary releases of software for now. Well, safer still is statically linking libpng, but yeah.

Thanks Rednaxela, this has been really helpful. If installing libpng12 is simple on most distros that don't ship with it, that sounds like the way to go.

I could still have a problem, though. wxWidgets will dynamically link to GTK, which dynamically links to system libpng. So I could then be linking to libpng12 and libpng15, which seems bad, but maybe it's not. I'll do some tests. Maybe I just have to build a separate binary release for Ubuntu/Debian and Fedora/Arch/Mageia, which isn't really a big deal.

Yeah, I installed libpng 1.2 and now I need libGLEW 1.8 (fedora's package mannager only has 1.7) It runs fine on Windows though!

Cool, thanks AW! Funny, Windows was the platform I was most worried about. :-) Btw are you on Windows 7?

I guess offering binaries compiled on several common Linux distros is probably a fairly safe way to go. Packaging as an RPM may help in defining/managing these dependencies, too, though.

Woot, thanks! And yeah, he's dumb like that. Chaser's even worse. :-)
