1 # Makefile that wraps the Gyp and build steps for Unix and Mac (but not Windows)
2 # Uses "ninja" to build the code.
4 # Some usage examples (tested on both Linux and Mac):
9 # # Build and run tests (in Debug mode)
13 # # Build and run tests (in Release mode)
14 # make dm BUILDTYPE=Release
17 # # Build bench and SampleApp (both in Release mode), and then run them
18 # make SampleApp bench BUILDTYPE=Release
19 # out/Release/bench -repeat 2
20 # out/Release/SampleApp
22 # # Build all targets (in Debug mode)
25 # If you want more fine-grained control, you can run gyp and then build the
26 # gyp-generated projects yourself.
28 # See https://skia.org for complete documentation.
34 # Soon we should be able to get rid of VALID_TARGETS, and just pass control
35 # to the gyp-generated Makefile for *any* target name.
36 # But that will be a bit complicated, so let's keep it for a future CL.
37 # Tracked as https://code.google.com/p/skia/issues/detail?id=947 ('eliminate
38 # need for VALID_TARGETS in toplevel Makefile')
40 # TODO(epoger): I'm not sure if the above comment is still valid in a ninja
60 # Default target. This must be listed before all other targets.
64 # As noted in http://code.google.com/p/skia/issues/detail?id=330 , building
65 # multiple targets in parallel was failing. The special .NOTPARALLEL target
66 # tells gnu make not to run targets within this Makefile in parallel.
67 # Targets that ninja builds at this Makefile's behest should not be affected.
