   3 # Make a shared library.
   4 # Basically do a switch/case depending on the OS and make a shared
   5 # lib conforming to that OS.
   6
   7
   8 # Usage:
   9 #   mklib [options] objects ...
  10 # Options:
  11 #   -o LIBRARY    specifies the name of resulting library
  12 #                 ("-o GL" for example, might result in "libGL.so" being made)
  13 #   -major N      specifies major version number (default is 1)
  14 #   -minor N      specifies minor version number (default is 0)
  15 #   -patch N      specifies patch version number (default is 0)
  16 #   -lLIBRARY     specifies a dependency on LIBRARY
  17 #   -LDIR         search in DIR for library dependencies
  18 #   -cplusplus    link with C++ runtime
  19 #   -static       make a static library (default is dynamic/shared)
  20 #   -install DIR  move resulting library files to DIR
  21 #   -arch ARCH    override using `uname` to determine architecture
  22 #   -archopt OPT  specify an extra achitecture-specific option OPT
  23 #
  24 # The library name should just be "GL" or "GLU", etc.  The 'lib' prefix
  25 # will be added here if needed, as well as the ".so" or ".a" suffix, etc.
  26 #
  27 # objects should be:  foo.o bar.o etc.o
  28 #
  29 # Environment variables recognized:
  30 #   CC   C compiler command
  31 #   CXX  C++ compiler command
