Build packages required:
cmake g++ flex bison python tcl

C++ requirements:
The compiler needs to support the TR1 extensions (e.g. shared_ptr<>). This program compiles successfully with g++ 4.2.1 on Mac OS X. Older compilers may need the appropriate boost implementations from

Python Requirements:
A version of Python 2.7.3 is recommended. However, this software should compile and link against previous versions of this software. This tool has not been tested on Python 3. Due to Python API inconsitencies, please compile Symdiff for your specific system. Currently tests are written for Python 2.6, but may use Python 2.7.3 language features.

Tcl Requirements:
Any version of Tcl of 8.4 and above should work. In principle, Symdiff libraries may be used across Tcl versions, because of the consistent API. Currently tests are written for Tcl 8.5.

Mac OS X:
Mac OS X developer tools are required.
Modify scripts/ as necessary for your configuration and run from the base directory of this project.
cd osx_release
make -j2

Modify scripts/ as necessary for your configuration and run from the base directory of this project.

Then go into the appropriate directory to build:
cd linux_x86_64_release
make -j2

Windows is not set up for the new cmake configuration. In principle it should work.

Running the tests:
make test

To run on your scripts go into the bin directory
symdiff for python
symdiff_tcl for tclsh

These set up the appropriate environment for loading SYMDIFF into your intepreter.

Documentation is in the doc directory. Examples are in the examples and testing directory.

(an example is provided in the Appendix below).

"Derivative Works" shall mean any work, whether in Source or Object
form, that is based on (or derived from) the Work and for which the

the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner
or by an individual or Legal Entity authorized to submit on behalf of
the copyright owner. For the purposes of this definition, "submitted"
means any form of electronic, verbal, or written communication sent

3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.

4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without

wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.

You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.

5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability. While redistributing

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
