Makefile

# Users of this package should not need to run this makefile.
#

# First build a static rocksdb lib.
# The build script already does this but you need to add a couple of options to the static build.
# Make the line look like:
# OPT ?= -O2 -DNDEBUG -fPIC -D_GLIBCXX_USE_CXX11_ABI=0

# The -fPIC enables linking the static lib into the object we will build.
# -D_GLIBCXX_USE_CXX11_ABI turns off the new c++11 abi. This means the build will be back compatible with
# older linux versions.

# Then set the source:

ROCKSDB_SOURCE=rocksdb/
DART_SDK=dart-sdk/

LIBS=$(ROCKSDB_SOURCE)/build/librocksdb.a
# Select prod/debug args
ARGS=-O2 -Wall -D_GLIBCXX_USE_CXX11_ABI=0 -std=c++11
# ARGS=-g -O0 -Wall -D_GLIBCXX_USE_CXX11_ABI=0
