# - 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_USE_ARM_ELF_TOOLS() - enable the ARM 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
|
||||||
|
# ECOS_ADD_EXECUTABLE(name source1 ... sourceN ) - create an executable for eCos
|
||||||
|
# ECOS_ADJUST_DIRECTORY(source1 ... sourceN )
|
||||||
|
#
|
||||||
|
# It contains the following variables:
|

|
# ECOS_DEFINITIONS
|
||||||
|
# ECOSCONFIG_EXECUTABLE
|
||||||
|
# for internal use only:
|

# ECOS_ADD_TARGET_LIB
