I'm trying to add a 3rd party dependency that depends on

tables

on mac m1. With vanilla

pip

, I install with extra brew packages and environment vars:

brew install hdf5 c-blosc lzo bzip2

export GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=1                                                     
export GRPC_PYTHON_BUILD_SYSTEM_ZLIB=1
export HDF5_DIR=/opt/homebrew/opt/hdf5                                                        
export BLOSC_DIR=/opt/homebrew/opt/c-blosc

Is there anyway I can propagate these environment vars to

pants

when its building requirement

pex

?

I think these options may be for you:

[subprocess-environment]
env_vars.add = [
  "GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=1",
  "GRPC_PYTHON_BUILD_SYSTEM_ZLIB=1",
]

[python-native-code]
cpp_flags = "-I/opt/homebrew/opt/openssl@3/include"
ld_flags = "-L/opt/homebrew/opt/openssl@3/lib"

cool. for me

[subprocess-environment]
env_vars.add = [
  "GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=1",
  "GRPC_PYTHON_BUILD_SYSTEM_ZLIB=1",
  "HDF5_DIR=/opt/homebrew/opt/hdf5",
  "BLOSC_DIR=/opt/homebrew/opt/c-blosc",
]

did the trick. Is there any easy way of making this environment specific? I need these only for mac m1
