B2SFinder is a binary-to-source matching tool for OSS reuse detection on COTS software. This project contains the core code of B2SFinder without implementation about database and pipeline.
A Windows server with python 2.7 (64-bit) and IDA 7.0.
A Linux server with python.
Step 0: Download the source code packages of candidate OSS projects.
Step 1: Extract code features of OSS projects.
$ cd SourceFeatureExtract
$ python extract_source_feature.py -pj_root <OSS_project_root>Step2: Compare targeted COTS software with all candidate OSS projects.
$ cd FeatureMatch
