4 *Linux users*: Before you run build_sdk.py (below), you must run::
6 GYP_DEFINES=target_arch=arm gclient runhooks
8 This will install some ARM-specific tools that are necessary to build the SDK.
12 To build the NaCl SDK, run::
14 build_tools/build_sdk.py
16 This will generate a new SDK in your out directory::
18 $CHROME_ROOT/out/pepper_XX
20 Where "XX" in pepper_XX is the current Chrome release (e.g. pepper_38).
22 The libraries will be built, but no examples will be built by default. This is
23 consistent with the SDK that is shipped to users.
29 To build all examples, you can run the test_sdk.py script::
31 build_tools/test_sdk.py
33 This will build all examples and tests, then run tests. It will take a long
34 time. You can run a subset of these "phases" by passing the desired phases as
35 arguments to test_sdk::
37 build_tools/test_sdk.py build_examples copy_tests build_tests
39 These are the valid phases:
41 * `build_examples`: Build all examples, for all configurations and toolchains.
42 (everything in the examples directory)
43 * `copy_tests`: Copy all tests to the SDK (everything in the tests directory)
44 * `build_tests`: Build all tests, for all configurations and toolchains.
45 * `sel_ldr_tests`: Run the sel_ldr tests; these run from the command line, and
46 are much faster that browser tests. They can't test PPAPI, however.
47 * `browser_tests`: Run the browser tests. This launches a locally built copy of
48 Chrome and runs all examples and tests for all configurations. It is very
52 Testing a Single Example/Test
53 =============================
55 To test a specific example, you can run the test_projects.py script::
57 # Test the core example. This will test all toolchains/configs.
58 build_tools/test_projects.py core
60 # Test the graphics_2d example, newlib/Debug only.
61 build_tools/test_projects.py graphics_2d -t newlib -c Debug
63 This assumes that the example is already built. If not, you can use the `-b`
64 flag to build it first::
66 build_tools/test_projects.py nacl_io_test -t newlib -c Debug -b
69 Rebuilding the Projects
70 =======================
72 If you have made changes to examples, libraries or tests directory, you can
73 copy these new sources to the built SDK by running build_projects.py::
75 build_tools/build_projects.py
77 You can then rebuild the example by running Make::
79 cd $CHROME_ROOT/out/pepper_XX
80 cd examples/api/graphics_2d # e.g. to rebuild the Graphics2D example.
83 You can build a specific toolchain/configuration combination::
85 make TOOLCHAIN=newlib CONFIG=Debug -j8
87 The valid toolchains are: `newlib`, `glibc`, `pnacl` and `bionic`.
88 The valid configurations are: `Debug` and `Release`.
92 # Run the default configuration
95 # Run the newlib/Debug configuration
96 make TOOLCHAIN=newlib CONFIG=Debug -j8
98 This will try to find Chrome and launch it. You can specify this manually via
99 the CHROME_PATH environment variable::
101 CHROME_PATH=/absolute/path/to/google-chrome make run
104 Building Standalone Examples/Tests
105 -------------------------------
107 Building the standalone tests is often more convenient, because they are faster
108 to run, and don't require a copy of Chrome. We often use the standalone tests
109 first when developing for nacl_io, for example. However, note that most tests
110 cannot be built this way.
112 To build the standalone configuration::
114 cd tests/nacl_io_test
115 make STANDALONE=1 TOOLCHAIN=newlib -j8
117 To run the standalone tests, you must specify an architecture explicitly::
119 make STANDALONE=1 TOOLCHAIN=newlib NACL_ARCH=x86_64 -j8 run
