GN build #411

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
switch from gyp to GN build.
1. r991 added BUILD.gn, supporting chrome builds of libyuv via GN.
2. r1317 added setup support to allow stand alone GN builds

Next steps are switching all gyp build scripts to GN, improving functionality 
and documenting how to build with GN

Does GN support different compilers?  vs2015 vs clang vs vs2013?

I don't think the win GN build supports clang yet.I believe vs2015 vs. vs2013 
*might* work, but I haven't tested it (we use pretty much the same underlying 
scripts to setup the toolchain for GN that we do for GYP).

I would cc' thakis and scottmg if I had edit rights on this :).

No one that I know of has tested GN-clang. Even gyp-clang is still 
non-mainstream on Windows.

I would guess that vs2015 "might" work too. The compiler is not yet shipped, 
and there's no bots testing chrome. So if it works, it's by chance, and if it 
breaks, you get both pieces (for now).

clang/win doesn't work in GN yet (see also the caveats at 
https://code.google.com/p/chromium/wiki/Clang#Windows ). I do want to look at 
that soon though.
