Build Fails on MacOS

Building python-rocksdb fails on recent version of MacOS. The final error you get is when linking with libstdc++:

clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9 [-Wdeprecated]
ld: library not found for -lstdc++
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'g++' failed with exit status 1

Summary of how to work around right now:

brew install rocksdb
export MACOSX_DEPLOYMENT_TARGET=10.9
pip install python-rocksdb

The pandas folks ran into this too; here is a discussion on how to resolve the issue by passing additional args to Clang: https://github.com/pandas-dev/pandas/issues/23424

export CFLAGS=-stdlib=libc++
pip install python-rocksdb

this works for me on macOS 10.14.3

The following procedure worked for me on:

• MacBook Pro M1
• macOS 12.2.1 Monterey
• rocksdb 6.29.3

Install rocksdb with brew:

brew install rocksdb

Use brew to look up the path on your system of the libs required for the install of python-rocksdb:

brew info rocksdb lz4 snappy

I had all libs already installed, maybe due to the install of rocksdb. If libs are missing, I guess you need to install them.

Export (for gcc?) the paths of the libs with CPPFLAGS and LDFLAGS and install python-rocksdb with pip. For me that was (adapt paths according to your setup):

export CPPFLAGS=-I/opt/homebrew/Cellar/rocksdb/6.29.3/include
export LDFLAGS="-L/opt/homebrew/Cellar/rocksdb/6.29.3/lib -L/opt/homebrew/Cellar/snappy/1.1.9/lib -L/opt/homebrew/Cellar/lz4/1.9.3/lib"
pip install python-rocksdb

The exports fixed also the poetry install of a poetry project with faust-streaming-rocksdb (faust-streaming = {extras = ["rocksdb"], version = "^0.8.2"}) as dependency.
