# Configuration script for the WFDB Software Package

# This script was not generated using 'autoconf'.  If you can implement
# autoconf input files for a 'configure' that does what this one does,
# please send them to me (george@mit.edu) for inclusion in a future
# version of this package.

# Note that any -m options (although parsed below) are currently ignored,
# except on x86_64 Linux, where they are prefixed to CFLAGS.  The help
# text below documents only -m32;  see the gcc manual for other -m options.

    --without-cygwin    on Cygwin, compile binaries that do not link to the
                         Cygwin DLL. WAVE will not be built.
    --without-netfiles  disable NETFILES even if libcurl or libwww is available

Summary:

$PACKAGE-$OS is now ready to be compiled using '$CC'.
The WFDB library will be compiled as a $LIBTYPE library $WITHNF NETFILES
 access${VIANF}, and it will be installed in '$DIR/$LIB'.
The WFDB library .h files will be installed in '$DIR/include/wfdb'.
The WFDB applications will be linked to $SYSLIBS system libraries, and
 they will be installed in '$DIR/bin'.
$WAVECOMP
Manual pages will be installed in subdirectories of '$MANDIR'.
Sample data files will be installed in '$DIR/database', which
 will be included in the default WFDB path.

WFDB software configuration is complete.
Now run 'make' to compile and test, followed by 'make install' to recompile
and install the software, man pages, and example data.  Finally, run
'make check' to verify that the installation is complete and successful.
