1 # - This module defines variables and macros required to build eCos application.
2 # This file contains the following macros:
3 # ECOS_ADD_INCLUDE_DIRECTORIES() - add the eCos include dirs
4 # ECOS_ADD_EXECUTABLE(name source1 ... sourceN ) - create an eCos executable
5 # ECOS_ADJUST_DIRECTORY(VAR source1 ... sourceN ) - adjusts the path of the source files and puts the result into VAR
7 # Macros for selecting the toolchain:
8 # ECOS_USE_ARM_ELF_TOOLS() - enable the ARM ELF toolchain for the directory where it is called
9 # ECOS_USE_I386_ELF_TOOLS() - enable the i386 ELF toolchain for the directory where it is called
10 # ECOS_USE_PPC_EABI_TOOLS() - enable the PowerPC toolchain for the directory where it is called
12 # It contains the following variables:
14 # ECOSCONFIG_EXECUTABLE
15 # ECOS_CONFIG_FILE - defaults to ecos.ecc, if your eCos configuration file has a different name, adjust this variable
16 # for internal use only:
