#                       BSP "PUBLIC" MAKEFILE CONTENT

#

# This file is intended to be included in an application or library

# Makefile that is using this BSP. You can create such a Makefile with

# the nios2-app-generate-makefile or nios2-lib-generate-makefile

# commands.

#

# The following variables must be defined before including this file:

#

#     ALT_LIBRARY_ROOT_DIR

#         Contains the path to the BSP top-level (aka root) directory

#------------------------------------------------------------------------------

#------------------------------------------------------------------------------

#                                  PATHS

#------------------------------------------------------------------------------

# Path to the provided linker script.

# Include paths:

# The path to root of all header files that a library wishes to make

# available for an application's use is specified here. Note that this

# may not be *all* folders within a hierarchy. For example, if it is

# desired that the application developer type:

#   #include 

#   #include 

# With files laid out like this:

#   /inc/sockets.h

#   /inc/ip/tcpip.h

#

# Then, only /inc need be added to the list of include

# directories. Alternatively, if you wish to be able to directly include

# all files in a hierarchy, separate paths to each folder in that

# hierarchy must be defined.

# The following are the "base" set of include paths for a BSP.

# These paths are appended to the list that individual software

# components, drivers, etc., add in the generated portion of this

# file (below).

# Enables lightweight device driver API. This reduces code and data footprint
