[Scons-users] How to import the env through which was env.SConscript( called

[Zarko Berberski (Aditi Staffing LLC)]

OK found the correct path (https://bitbucket.org/dirkbaechle/scons_talks/src/82c1f521676ab61f0d436bb1f8e659f5c377cbb3/pyconde_2013/examples/exvar/?at=default)
but it doesn't work for me (scons-2.5.0) when I use deliberately different name:

env_LKG = env.Clone()
    no_prior, top_LKG = env_LKG.SConscript('ocaml-LKG/ocaml-output.scons', export={'My_env' : env_LKG})
. . . .
Import('My_env')


ð  UseError: Import of non-existent variable ''My_env''

If I use export={'env' : env_LKG} / Import('env')

Then it happily imports the main env - from which env_LKG was cloned

Hi Zarko,

I do a clone and call Sconcript with that clone, but that connection seems to be lost

I can't import by name since identical scripts needs to build in 2 folders (which may become -  variant_dir) => they shouldn't know which env to import - they should work with the one that's given to them.


please check out the example

from the main "SCons talks" repo https://bitbucket.org/dirkbaechle/scons_talks<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbitbucket.org%2Fdirkbaechle%2Fscons_talks&data=02%7C01%7Cv-zaberb%40microsoft.com%7C9ee3375f30aa4580d6ad08d4b247eca9%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636329469370820209&sdata=ShKEDLLOVlTh5HEuhiK%2FZ3mYnCKSWnyr76gh6vn%2FBuo%3D&reserved=0> . It shows how to use the "export" keyword for SConscript, which is the canonical way of doing what you're trying to accomplish.

Best regards,

Dirk
