- # 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.
