# 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"
|
|
#
|
|
# 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
|
|
#
|
|
# 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.
