Summary: This patch will update the Makefile and source code so that we can build RocksDB successfully on FreeBSD 10 and 11 (64-bit and 32-bit) I have also encountered some problems when running tests on FreeBSD, I will try to fix them individually in different diffs Notes: - FreeBSD uses clang as it's default compiler (http://lists.freebsd.org/pipermail/freebsd-current/2012-September/036480.html) - GNU C++ compiler have C++ 11 problems on FreeBSD (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193528) - make is not gmake on FreeBSD (http://www.khmere.com/freebsd_book/html/ch01.html) Test Plan: Using VMWare Fusion Create 4 VM machines (FreeBSD 11 64-bit, FreeBSD 11 32-bit, FreeBSD 10 64-bit, FreeBSD 10 32-bit) - pkg install git gmake gflags archivers/snappy - git clone https://github.com/facebook/rocksdb.git - apply this patch - setenv CXX c++ - setenv CPATH /usr/local/include/ - setenv LIBRARY_PATH /usr/local/lib/ - gmake db_bench - make sure compilation is successful and db_bench is running - gmake all - make sure compilation is successful Reviewers: sdong, igor Reviewed By: igor Subscribers: dhruba Differential Revision: https://reviews.facebook.net/D33891
