                 libdmtx README file (Mac OS X)

This README.osx file contains information on installing and using
libdmtx on Mac OS X. The general README file, also found in this
directory, contains a high level summary of libdmtx and its
components.


1. Installing libdmtx on Mac OS X
-----------------------------------------------------------------

libdmtx can be installed on OS X using the instructions provided
in the general README file. However, please see below for
additional details that might benefit users on this platform.


2. Universal Binaries
-----------------------------------------------------------------

You can tweak configure's parameters to build an Universal Binary
version of the library. Recommendations are provided at:

3. Dependencies
-----------------------------------------------------------------

Some libdmtx command line utilities have dependencies on external
software. For example:

  * dmtxread requires GraphicsMagick, which must be downloaded
    and built from its source distribution. After doing this,
    simply add the relevant "-L" and "-I" options to the CFLAGS
    and LDFLAGS environment variables before running the
    ./configure script.

  * dmtxwrite requires libpng, which can be installed easily with
    MacPorts.

Compiling from Subversion requires a working autoconf/pkg-config
setup:

  * autoconf, automake, libtool, and pkgconfig are required to
    generate the configure script. These packages are available
    from MacPorts.

  * You may run into issues if you mix the autotools packages in
    MacPorts with the ones installed from Xcode Tools. Make sure
    /opt/local/bin appears before /usr/bin in your $PATH.
