-# configure script for zlib. This script is needed only if
-# you wish to build a shared library and your system supports them,
-# of if you need special compiler, flags or install directory.
-# Otherwise, you can just use directly "make test; make install"
+# configure script for zlib.
#
-# To create a shared library, use "configure --shared"; by default a static
-# library is created. If the primitive shared library support provided here
-# does not work, use ftp://prep.ai.mit.edu/pub/gnu/libtool-*.tar.gz
+# Normally configure builds both a static and a shared library.
+# If you want to build just a static library, use: ./configure --static
#
# To impose specific compiler or flags or install directory, use for example:
# prefix=$HOME CC=cc CFLAGS="-O4" ./configure
# or for csh/tcsh users:
# (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)
-# LDSHARED is the command to be used to create a shared library
# Incorrect settings of CC or CFLAGS may prevent creating a shared library.
# If you have problems, try without defining CC and CFLAGS before reporting
# an error.
