| Variables |
|---|
| **`cobalt_licenses_platform`** Sub-directory to copy license file to. The default value is `"default"`. |
| **`cobalt_platform_dependencies`** List of platform-specific targets that get compiled into cobalt. The default value is `[]`. |
| **`cobalt_v8_emit_builtins_as_inline_asm`** Some compiler can not compile with raw assembly(.S files) and v8 converts asm to inline assembly for these platforms. The default value is `false`. |
| **`final_executable_type`** The target type for executable targets. Allows changing the target type on platforms where the native code may require an additional packaging step (ex. Android). The default value is `"shared_library"`. |
| **`gl_type`** The source of EGL and GLES headers and libraries. Valid values (case and everything sensitive!): - `system_gles2` - Use the system implementation of EGL + GLES2. The headers and libraries must be on the system include and link paths. - `angle` - Use ANGLE's EGL + GLES2 implementation. This requires a valid ANGLE implementation for the platform. The default value is `"system_gles2"`. |
| **`gtest_target_type`** The target type for test targets. Allows changing the target type on platforms where the native code may require an additional packaging step (ex. Android). The default value is `"shared_library"`. |
| **`has_platform_targets`** Whether the platform has platform-specific targets to depend on. The default value is `false`. |
| **`loadable_module_configs`** Target-specific configurations for loadable_module targets. The default value is `[]`. |
| **`nasm_exists`** Enables the nasm compiler to be used to compile .asm files. The default value is `false`. |
| **`path_to_nasm`** Where yasm can be found on the host device. The default value is `"nasm"`. |
| **`platform_tests_path`** Set to the starboard_platform_tests target if the platform implements them. The default value is `""`. |
| **`sabi_path`** Where the Starboard ABI file for this platform can be found. The default value is `"starboard/sabi/default/sabi.json"`. |
| **`sb_api_version`** The Starboard API version of the current build configuration. The default value is meant to be overridden by a Starboard ABI file. The default value is `18`. |
| **`sb_enable_benchmark`** Used to enable benchmarks. The default value is `false`. |
| **`sb_enable_cpp17_audit`** Enables an NPLB audit of C++17 support. The default value is `true`. |
| **`sb_enable_cpp20_audit`** Enables an NPLB audit of C++20 support. The default value is `true`. |
| **`sb_enable_lib`** Enables embedding Cobalt as a shared library within another app. This requires a 'lib' starboard implementation for the corresponding platform. The default value is `false`. |
| **`sb_enable_opus_sse`** Enables optimizations on SSE compatible platforms. The default value is `true`. |
| **`sb_evergreen_compatible_use_libunwind`** Whether to use the libunwind library on Evergreen compatible platform. The default value is `false`. |
| **`sb_filter_based_player`** Used to indicate that the player is filter based. The default value is `true`. |
| **`sb_has_unused_symbol_issue`** Set this to true if the modular toolchain linker doesn't strip all unused symbols and nplb fails to link. The default value is `false`. |
| **`sb_libevent_method`** The event polling mechanism available on this platform to support libevent. Platforms may redefine to 'poll' if necessary. Other mechanisms, e.g. devpoll, kqueue, select, are not yet supported. The default value is `"epoll"`. |
| **`sb_static_contents_output_data_dir`** Directory path to static contents' data. The default value is `"/project_out_dir"`. |
| **`sb_use_no_rtti`** Whether or not to disable run-time type information (adding no_rtti flag). The default value is `false`. |
| **`source_set_configs`** Target-specific configurations for source_set targets. The default value is `[]`. |
| **`starboard_level_final_executable_type`** The default value is `"executable"`. |
| **`starboard_level_gtest_target_type`** The default value is `"executable"`. |
| **`static_library_configs`** Target-specific configurations for static_library targets. The default value is `[]`. |
| **`use_crashpad`** Platforms can set this to false to avoid building and using a real crashpad implementation. If false, crashpad either won't be built or a stub implementation will be built and used. all Early Access Program platforms. The default value is `true`. |
| **`v8_enable_pointer_compression_override`** Set to true to enable pointer compression for v8. The default value is `true`. |
