   2 # configure script for zlib.
   3 #
   4 # Normally configure builds both a static and a shared library.
   5 # If you want to build just a static library, use: ./configure --static
   6 #
   7 # To impose specific compiler or flags or install directory, use for example:
   8 #    prefix=$HOME CC=cc CFLAGS="-O4" ./configure
   9 # or for csh/tcsh users:
  10 #    (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)
  11
  12 # Incorrect settings of CC or CFLAGS may prevent creating a shared library.
  13 # If you have problems, try without defining CC and CFLAGS before reporting
  14 # an error.
