# CONFIGURE CORE PLATFORM MAKEFILE
#   This file has linux common rules for all the platforms (x86_64, i386,armv6l
#   and armv7l)
#
################################################################################

################################################################################
# PLATFORM SPECIFIC CHECKS
#   This is a platform defined section to create internal flags to enable or
#   disable the addition of various features within this makefile.  For
#   instance, on Linux, we check to see if there GTK+-2.0 is defined, allowing
#   us to include that library and generate DEFINES that are interpreted as
#   ifdefs within the openFrameworks core source code.

# PLATFORM DEFINES
#   Create a list of DEFINES for this platform.  The list will be converted into
#   CFLAGS with the "-D" flag later in the makefile.  An example of fully
#   qualified flag might look something like this: -DTARGET_OPENGLES2
#
#   DEFINES are used throughout the openFrameworks code, especially when making
#   #ifdef decisions for cross-platform compatibility.  For instance, when
#   choosing a video playback framework, the openFrameworks base classes look at
#   the DEFINES to determine what source files to include or what default player
#   to use.

# PLATFORM REQUIRED ADDON

#   required addon header files as needed within the core.
#
#   For instance, if you are compiling for Android, you would add ofxAndroid
#   here. If you are compiling for Raspberry Pi, you would add ofxRaspberryPi
#   here.
