#
# <!-- ***************************************************************** -->

# <!-- ***************************************************************** -->
#
# If you get the error:

#
# Download and compile `freetype` with version lower than 2.5.
# Follow "Problem number two" steps at:

# <http://mattaw.blogspot.com/2014/05/making-modelsim-altera-starter-edition.html>
# It's hard to visit.So you
# Compile freetype first
# Copy freetype-2.4/freetype-2.4.0/objs/.libs/libfreetype.so\* to dir
# And change vco like :
