################################   MAKEFILE OPTIONS     ####################################

# If ENABLE_GRAPHICS is set to true, VPR requires X11 to compile.  
# On Ubuntu, type 'make packages' or 
# 'sudo apt-get install libx11-dev' to install.  
# Please look online for information on how to install X11 on other Linux distributions.

# Please note that a Mac can run the graphics if the X11 library is installed. 

ENABLE_GRAPHICS = false
# can be true or false

export BUILD_TYPE = debug
# can be debug or release - this option gets inherited by the library libarchfpga 
# by default, though libarchfpga's build type can be set independently in libarchfpga's Makefile.

COMPILER = g++

OPTIMIZATION_LEVEL_FOR_RELEASE_BUILD = -O3
# can be -O0 (no optimization) to -O3 (full optimization), or -Os (optimize space)
