# Detects OS we're compiling on and outputs a file specified by the first
# argument, which in turn gets read while processing Makefile.
#
# The output will set the following variables:
# CC C Compiler path
# CXX C++ Compiler path
# PLATFORM_LDFLAGS Linker flags
# JAVA_LDFLAGS Linker flags for RocksDBJava
# PLATFORM_SHARED_EXT Extension for shared libraries
# PLATFORM_SHARED_LDFLAGS Flags for building shared library
# PLATFORM_SHARED_CFLAGS Flags for compiling objects for shared library
# PLATFORM_CCFLAGS C compiler flags
# PLATFORM_CXXFLAGS C++ compiler flags. Will contain:
# PLATFORM_SHARED_VERSIONED Set to 'true' if platform supports versioned
# shared libraries, empty otherwise.
#
# The PLATFORM_CCFLAGS and PLATFORM_CXXFLAGS might include the following:
#
# -DLEVELDB_PLATFORM_POSIX if cstdatomic is present
# -DLEVELDB_PLATFORM_NOATOMIC if it is not
# -DSNAPPY if the Snappy library is present
# -DLZ4 if the LZ4 library is present
# -DNUMA if the NUMA library is present
#
# Using gflags in rocksdb:
# Our project depends on gflags, which requires users to take some extra steps
# before they can compile the whole repository:
# 1. Install gflags. You may download it from here:
# https://code.google.com/p/gflags/
# 2. Once install, add the include path/lib path for gflags to CPATH and
# LIBRARY_PATH respectively. If installed with default mode, the
# lib and include path will be /usr/local/lib and /usr/local/include
# Mac user can do this by running build_tools/mac-install-gflags.sh
