Is there an open source tool that searches your codebase for improperly used open source code?

Question

Seems like there should be an Open Source tool that helps companies enforce OpenSource licensing compliance? The only open source tool we've been able to find only scans headers, it does not check the source code itself for pattern matches.

There are closed source tools which we will use if we must, but I thought as a last-ditch effort I'd check here since the tools tend to be licensed & quite pricey (the one we are looking at charge per file scanned which can be a pretty large fee over time).

Any help is greatly appreciated.

Answer 1

That's tough. The closest I can think of is searching for your code at google.com/codesearch
