ninja generator should support cross-compilation #213

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The make gyp generator has .target and .host variants for the 
compiler/linker/helper binaries & flags, to support cross-compilation (e.g. 
building ARM binaries in an x64 chroot): 
https://github.com/martine/gyp/blob/ninja/pylib/gyp/generator/make.py#L119

ATM ninja can't be used to cross-compile this way, because it ignores whether 
build targets should be built for "host" or "target" platforms. IWBN if ninja 
did support this mode of work.

For interested early-adopters:

https://chromiumcodereview.appspot.com/9417030/ implements cross-compilation 
support in ninja; see first comment in review log for details on how I use it.

Note that if specifically building chromium on a platform that requires libvpx, 
this CL is required and although it's landed DEPS hasn't rolled to it yet (hung 
up on unrelated libvpx borkedness):

Patch locally to play with it.

Enable cross-compilation with ninja.

Replaced the specialness of _host with _target, b/c the _host
toolchain is usually the vanilla gcc/g++, so it looks better to
leave those variables alone (plus, it mirrors make.py and
GypPathToUniqueOutput).

Added an AR to the family b/c it differs between host & target.

Made generator_supports_multiple_toolsets depend on the presence
of any of the $FOO_target variables as an intermediate hack
around the double-building problem.
