| # Common makefile definitions for building applications based |
| # on the Silicon Labs EFR32 SDK. |
| # |
| |
| # |
| # This makefile is primarily intended to support building the |
| # CHIP example applications on Silicon Labs platforms. However |
| # external developers should feel free to use it if they find |
| # it useful. |
| # |
| # To build an application using this makefile, include the file |
| # in a project-specific Makefile, define make variables describing |
| # the application and how it should be built, and then call the |
| # GenerateBuildRules function. E.g.: |
| # |
| # PROJECT_ROOT = $(realpath .) |
| # |
| # BUILD_SUPPORT_DIR = $(PROJECT_ROOT)/third_party/connectedhomeip/build/efr32 |
| # |
| # include $(BUILD_SUPPORT_DIR)/efr32-app.mk |
| # include $(BUILD_SUPPORT_DIR)/efr32-chip.mk |
| # |
| # APP := chip-efr32-bringup |
| # |
| # SRCS = \ |
| # $(PROJECT_ROOT)/main.cpp \ |
| # ... |
| # |
| # INC_DIRS = \ |
| # $(PROJECT_ROOT) \ |
| # ... |
| # |
| # LIBS = \ |

| # DEFINES = \ |
