# Note:
# - This is a convenience makefile that you can use in the case that you build
#   on Linux but there is no specific makefile for the architecture that you are
#   building for. Normally, the architecture is hardcoded into the makefile,
#   like you can see in Makefile.i86Linux2.6gcc4.4.5. In stead, this makefile
#   tries to figure out what your installed architecture is by scanning your
#   LD_LIBRARY_PATH.

# - To use this Makefile, you must have the 'NDDSHOME' environment variable
#   set to the location of RTI Connext and LD_LIBRARY_PATH must contain
#   the RTI DDS libraries. An easy way to achieve this is by sourcing the
#   RTI-provided environment script found in $NDDSHOME/resource/srcipts,
#   for example
#   . $NDDSHOME/resource/scripts/rtisetenv_i86Linux3.xgcc4.6.3.bash
# 
# - You need to invoke the make command from the root directory of this example.
#
# - To enable debugging information, set the Makefile variable 'DEBUG' to '1'.
#
# Example:
#   make -f make/Makefile.Linux


# Defines required Make variables. They will be used in the Makefile.common
# to define the rules to define the build process for this application.
