@yangbenfa What is the version of GCC and CentOS? The latest RE2 upstream library uses a lot of C++11 features, eg. C++11 thread and mutex. The package will require R > 3.3, which will use at least GCC 4.9.3 on CRAN.

The package will be released to CRAN, when this upstream issue google/re2#102 is solved. CRAN now also uses GCC 6.1.1 20160802 which has the bug to compile RE2.
