CCFinderX is a tool for detecting code clones from source code, originally developed by Toshiro Kamiya. It is a re-design a previous tool CCFinder, described in the paper "CCFinder: A Multi-Linguistic Token-based Code Clone Detection System for Large Scale Source Code".
CCFindeX can extract code code clones correctly from source code even in cases where the names of variables habe changed.
- Detect duplicated code written in Java, C, C++, COBOL, VisualBasic and C#.
- Multi-threadding for multi-core CPU
- AST-based preprocessing with an island-parser like parser.
- Search functions
- Support for programming languages in (as possible as) equal level.
- Users can adapt the tool to another programming languages or dialects.
- Analysis using metrics of code clone
- For interoperability with another tools, the tool can read/write data in TSV(tab separated values) text format.
- Code clone shaper as described in "On Software Maintenance Process Improvement Based On Code Clone Analysis"
- Support for parameterized match (P-match) as described in "On finding Duplication and Near-Duplication in Large Software System".
- Interactive analysis with multiple views of GUI front-end GemX, a re-implementation of Gemini, described in "Gemini: Code Clone Analysis Tool".
This is a clone of CCFinderX that has the settings to build with autoconf on a Linux machine.
ccfinderx requires the development packages for Python, Boost, JNI (Java SDK), and ICU.
On Debian 8 (jessie), you need at least the following packages installed: # aptitude install libtool autoconf automake make build-essential autoconf-archive
You'll also need various Boost libraries, it may be easiest to just do:
# aptitude install libboost-all-dev
Note that autconf-archive is important to get AX_JNI_INCLUDE_DIR and
AX_BOOST_BASE referenced in configure.ac.
After dependencies are installed, the process to build ccfinderx is:
$ libtoolize
$ aclocal -I m4 --install
$ autoconf
$ automake --foreign --add-missing
$ ./configure
$ make
If there is an error in make ccfinderx_CCFinderX.h, then is necessary to generate it via:
$ cd GemX
$ make ccfinderx_CCFinderX_h
To build GemX (the graphical user interface):
$ cd GemX
$ make
