How to build (using scons, on Linux): $ cd ots/test/ $ sudo apt-get install scons g++ libfreetype6-dev $ scons How to build (using gyp): (Note: test programs which require gtest can't build with gyp for now) 1. If you are building OTS on Windows, download zlib from http://www.zlib.net/ and put them in third_party/zlib. 2. Run gyp_ots $ ./gyp_ots This will fetch gyp and generate build files. By default, following files will be generated: - MSVS solution file on Windows - Xcode project file on Mac - Makefile on Linux If you want to generate Makefile on Mac, you can use -f option: $ ./gyp_ots -f make 3. Build OTS Using MSVS: Open ots-standalone.sln and build targets. Using Xcode: $ xcodebuild -target ots-standalone.xcodeproj -target all Using Makefile: $ make
