README for IEGenLib
=================================
IEGenLib is a library that represents and manipulates integer sets and
relations that have affine and uninterpreted function constraints.

====  I. Getting The Source Code ===================

The IEGenLib library is being actively developed, and new functionalities
are being added. You can get the latest source code from this git repository:

    git clone https://github.com/CompOpt4Apps/IEGenLib


==== II. Quick Start ===============

  A. Building IEGenLib
  B. Simplifying constraints set containing Uninterpreted Function Calls

---- A. Building IEGenLib ----------

If you want to do a quick build, just run:
    ./configure
    make
    make test
 
This will install into a directory IEGenLib/iegenlib
Set IEGEN_HOME to /full/path/to/IEGenLib/iegen


---- B. Replicating relation simplification result from the SC 2016 paper ---

Please look at SC_IEGenLib branch for this.



==== III. Distribution Organization ===============

The distribution is shipped as a tar file. When you unpack the tar
file it creates a directory that is the root of the distribution.

    tar xzvf iegenlib-#.#.#.tgz

Sources for the project are found in the distribution root src/
sub-directory.

The library and demonstration driver create both string and dot
output; graphviz is needed to visualize the dot output.
      

==== IV. Building IEGenLib from Source =======================

    Build Command Sequence
        ./configure
        make
        make install

    Build and Test without creating an install directory
        ./configure
        make
        make test
       

    Requirements
        * cmake 2.6 or newer
        
        * C++ compiler, the below versions are known to work
            Mac i686-apple-darwin10-g++-4.2.1, 
            GCC 4.6.3 20120306 (Red Hat 4.6.3-2)
            
        * If re-generating parser files BISON 2.4 and FLEX 2.5 or newer
        
        * If re-generating docs
            * doxygen (http://www.stack.nl/~dimitri/doxygen/index.html,
                       known to work with 1.5.6 and 1.7.5)
            * dot (http://www.graphviz.org)
 
        * If you plan to change the grammar for the sets or relations:
            * Flex: version 2.5.35 known to work
            * Bison: version 2.4.1 known to work

Please notify us if you find that other versions of these tools that
work or do not work for you.

Build files for the project are generated using cmake (except for the
distribution root-level Makefile that is included in the tar file).
Cmake version 2.6 or newer is required. Make files can be generated to
only build the binaries, to additionally generate the parser files.
These options are enabled through a configure script in the root of the
project. If the parser option is included, then additionally FLEX
version 2.5 or newer and BISON version 2.4 or newer are required. If
documentation is to be re-generated, then doxygen and dot are also
required to create it.

Run ./configure --help for more build configuration options.

The default install directory is ${IEGEN_DIR}/iegen/. This directory
may be changed using options to the configure script.  Note that the
cmake system places binaries in an iegen/ directory, rather than an
iegen-LINUX64/ or iegen-MacOSX/ directory as are shipped in the
distribution.


==== V. Running Tests =====

The iegen/bin/run_iegenlib_tests binary can be executed to run the tests of 
the various components of IEGenLib. Additionally, from the root of the 
distribution you can run 'make test' to run these same tests.

The gtest framework is used for writing and running unit tests.  Information 
on gtest can be found at:

    http://code.google.com/p/googletest/

and introductory documentation is at:

    http://code.google.com/p/googletest/wiki/V1_6_Primer

==== VI. Documentation =====

To create the doxygen documentation, run the following command:

    make docs

An index.html file will be created in the distribution root directory, in 
doc/html/. A latex pdf file, called refman.pdf will also be created, in the 
doc/latex/ directory. 

==== VII. Debug and Release Builds =====

The default build is the debug build.  It is set by cmake in the configure 
script with -DCMAKE_BUILD_TYPE:STRING=Debug.  The compiler options for the 
debug build are '-O0 -g'.  

To create a release version, use in the -build--release option to the 
configure script. The compiler options for the release are '-O3 -DNDEBUG'.

To show actual build commands, you can run the verbose version of the build:
  
  make install VERBOSE=1
