| # - 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 |
| # for internal use only: |
| # ECOS_ADD_TARGET_LIB |
