RE2 should build and run on any modern Unix clone with GCC or Clang.

git clone https://code.googlesource.com/re2
cd re2
make
make test
make install
make testinstall

(On BSD systems, use gmake instead of make.)

Building RE2 requires Abseil (https://github.com/abseil/abseil-cpp) to be installed on your system. Building the testing for RE2 requires GoogleTest (https://github.com/google/googletest) and Benchmark (https://github.com/google/benchmark) to be installed as well.

Bazel and CMake are also supported. The latter enables generation of Visual Studio and Xcode projects as well as Cygwin, MinGW and MSYS makefiles. Bug reports and/or fixes are welcome!

Your compiler must support C++14.
Visual Studio users: You need Visual Studio 2019 or later.
Cygwin users: You must run CMake from the Cygwin command line, not the Windows command line.

For documentation on how to use RE2, see the comment at the top of re2/re2.h.
