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.
