epoger@google.com5d2e4cc2011-06-22 19:17:28 +00001# Makefile that wraps the Gyp and build steps for Unix and Mac (but not Windows)
2# Uses "make" to build on Unix, and "xcodebuild" to build on Mac.
3#
4# Some usage examples (tested on both Linux and Mac):
5#
6# # Clean everything
7# make clean
8#
9# # Build and run tests (in Debug mode)
10# make tests
11# out/Debug/tests
12#
13# # Build and run tests (in Release mode)
14# make tests BUILDTYPE=Release
15# out/Release/tests
16#
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
21#
22# # Build all targets (in Debug mode)
23# make
24#
25# If you want more fine-grained control, you can run gyp and then build the
26# gyp-generated projects yourself.
27#
28# See http://code.google.com/p/skia/wiki/DocRoot for complete documentation.
