# CC 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

# FIND Command for the find utility
|

# WATCH Command for the watch utility

# before they can compile the whole repository:
|

# 1. Install gflags. You may download it from here:
|
|
# https://gflags.github.io/gflags/ (Mac users can `brew install gflags`)
|
|
# 2. Once installed, add the include path for gflags to your CPATH env var and
|
|
# the lib path to LIBRARY_PATH. If installed with default settings, the lib
|
|
# will be /usr/local/lib and the include path will be /usr/local/include
