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