What's a portable and lightweight C/C++ regular expression library? [closed]

Lightweight and portable regex library for C/C++?

I'm looking for a C++ (C is acceptable, too) library for matching regular expressions. The library should satisfy these requirements:

• Can be built on Windows (MSVC 7 and newer)
• Can be built on Linux (g++ 3.4 and newer).
• Has no external dependencies; nothing but C/C++ runtime and STL allowed
• Works reasonably fast for small (~200 characters) strings to match against

I don't need a particular regexp flavor (POSIX, PCRE etc.) so anything is fine.

So far, I considered these libraries:

• re2: Interesting, but apparently no support for Windows builds
• PCRE doesn't seem terribly 'small' (over 1MB zipped sources) and doesn't seem to support Windows in its buildsystem.
• Boost Regex might fit the bill but I didn't spend much time on trying to figure out if I can build it standalone

Anything else maybe?

Answer 1

A quick Google for "pcre windows" seems to say that it does, in fact, support Windows. The .so file on my system is < 200 KiB, so it doesn't seem to take up that much disk space either...

Answer 2

Try the GNU regex library.

There's been at least one windows port:
