SDL Version

Post by booner »

Hello all. Working on getting a development environment to compile Wesnoth. In http://wiki.wesnoth.org/CompilingWesnoth#Prerequisites it is suggested that there is a known bug with SDL 1.2.14 that can be solved by downgrading to 1.2.13. With SDL-1.2.15 now available would anyone know if that bug is no longer an issue?

I'm not actually sure what the bug is, but for what it's worth I have often compiled with SDL 1.2.15 and had no problem.
Also it seems the official windows library deps collection comes with SDL 1.2.15.

Thanks iceiceice. I will go with *.15 and see how it goes then.

Out of curiosity, where are the official dependencies for Wesnoth for Windows? According to the file details, the SDL.dll from the Code::Blocks dependencies download, the 1.11.19 download on the main page, and the one I got from loonycyborg are all 1.2.14.

Uh oh, that might be a bug then.

When I go to the source forge > wesnoth > SDK section and download the 1.11 deps collection:
http://sourceforge.net/projects/wesnoth ... p/download

if I go to include/SDL/SDL_version.h, I see that it defines the version as 1.2.15.

Maybe a header vs .dll mismatch?

Maybe? It sounds right, but that's a bit above my level of knowledge of c++.

Just to follow up on this:

- The header vs dll mismatch is indeed a minor bug but unless the headers for 1.2.14 and 1.2.15 are actually different, and we use one of the functions that is different, it's not a problem. If it were a problem there would probably be many reports of crashes which backtrace into SDL, since there aren't this is low priority.

- The original bug related to SDL 1.2.14 was here: https://gna.org/bugs/?14770
I stumbled across mention of this in the wiki, on an unrelated purpose...

It seems to be mainly GNU linux related. If there are mouse clicking bugs in windows releases then the outdated SDL version might be the culprit, but if this isn't reported then it's probably not an issue for windows.

I was about to ask the same thing, so it is nice to see this thread with all the links.

Note that Wesnoth bug is specifically fixed in SDL 1.2.15 by Sam Lantinga here.

The only confusing place is INSTALL instruction - https://github.com/wesnoth/wesnoth/pull/348
