In 0.33.0 python2 support has been removed from mpv's build system. This
commit removes python2 compatibility code from bootstrap.py with the
following changes:
- __future__ import for print_function is not needed
- urllib2 is python2 only
Upstream waf still ships with the default interpreter being "python",
though the script works with both Python 2 and Python 3 (they're not
changing the default choice during 2.0.x releases for compatibility
reasons apparently). Add code to bootstrap.py to change the
interpreter from "python" to "python3" when downloading the "waf"
file.
Running any mpv code under Python 2 should be considered unsupported
in the future (and any code added need not work under Python 2).
There have been mentions that there are apparently some bugs with
regards to possible random build failures, so bumping after a few
years sounds like an OK thing to test/do.
With this option, the script will check that the expected waf version is
present, but will simply fail if it's not, rather than trying to
download it. This allows a package build script to avoid compile-time
network access but still ensure it's using the right waf version.
Apparently, just running ./waf and hoping that it will be run with a
Python interpreter doesn't necessarily work. The workaround is pretty
simple and reliable.
It seems like a good idea not to generate any additional network traffic
and wait times if we don't have to.
Also print the URL it's downloading from.
Note that if we require a newer waf release, there will be a problem.
Running ./bootstrap.py won't get the newest waf version anymore in case
the old version is in the source dir. Not sure how to handle this.
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.
