What is a portable and lightweight C / C ++ regular expression library?

Possible duplicate:
Lightweight and portable regex library for C / C ++?

I am looking for a C ++ library (C also acceptable) for matching regular expressions. The library must meet the following requirements:

  • Can be built on Windows (MSVC 7 and later)
  • It can be built on Linux (g ++ 3.4 and later).
  • It has no external dependencies; nothing but the C / C ++ and STL runtimes allowed
  • Works fast enough for small (~ 200 characters) lines to match

I don’t need a special regexp taste (POSIX, PCRE, etc.), so everything is in order.

So far I have been looking at these libraries:

  • re2 : Interesting, but apparently Windows support doesn't build
  • PCRE does not look terribly “small” (more than 1 MB with a zipper) and does not seem to support Windows in its buildsystem.
  • Boost Regex can fit in the bill, but I didn’t spend much time figuring out if I could build it autonomously

Can anything else be?

The quick google for "pcre windows" seems to say that it actually supports Windows. The .so file on my system is <200 KiB, so it doesn't seem to take up so much disk space ...

The standard C ++ TR1 libraries contain regular expression classes. Newer versions of MSVC contain an implementation and there is Boost.Regex as an independent compiler implementation.

My! But you have to download it as part of another tool - csvfix . The regular expression code is in the alib library, based on the code in Software Tools In Pascal, ported with a lot of changes to C ++. It is very small, about 30 thousand. Or less from the source, supports ed-style rexers, compiles on Windows and Linux, and I would like others to improve it.

Boost.Regex will match your score in terms of compilers, although it has dependencies on other parts of the increase.
