This commit adds a new build system based on waf. configure and Makefile
are deprecated effective immediately and someday in the future they will be
removed (they are still available by running ./old-configure).
You can find how the choice for waf came to be in `DOCS/waf-buildsystem.rst`.
TL;DR: we couldn't get the same level of abstraction and customization with
other build systems we tried (CMake and autotools).
For guidance on how to build the software now, take a look at README.md
and the cross compilation guide.
CREDITS:
This is a squash of ~250 commits. Some of them are not by me, so here is the
deserved attribution:
- @wm4 contributed some Windows fixes, renamed configure to old-configure
and contributed to the bootstrap script. Also, GNU/Linux testing.
- @lachs0r contributed some Windows fixes and the bootstrap script.
- @Nikoli contributed a lot of testing and discovered many bugs.
- @CrimsonVoid contributed changes to the bootstrap script.
This issue hits users way too often. Copy the explanation printed by the
configure script to the README to give it more visibility.
We will fix this properly once we have a new build system.
Travis-CI [1] is a continous integration cloud service. It is free for
open-source projects and tigthly integrated tiwh GitHub so there is really
no reason for us not use it. :)
For now we are going to do a total of 4 builds, mainly to test ffmpeg/libav
API breakage:
* ffmpeg-stable, libass-stable
* ffmpeg-git, libass-stable
* libav-stable, libass-stable
* libav-git, libass-stable
The compiler that is currently used is clang for two reasons:
* running 8 build targets would be quite wasteful and take a long time
* clang is less tested and used during development than gcc (especially on
linux)
Currently Travis doesn't support OS X environments alongside Linux ones [2].
When it will, we will add a fifth build target to test OS X compilation
breakage.
README was moved to markdown to add the little build status image. I ran some
tests with my GitHub fork and couldn't get images to show up using ReStructured
Text.
