linux 下svgalib编的一个界面程序示例

#---------------------------------------------------------------------OU
# Makefile for SVGAlib.
#
# It's pretty unreadable, but just doing make install should be
# enough. This will install the headerfiles and shared library first
# (which is enough to compile things), after which the static version is
# optionally compiled and installed (if it fails, the shared libraries
# should still work fine).
#
#----------------------------------------------------------------------

# *** NO SERVICIBLE PARTS HERE!
#     All options are in Makefile.cfg.
