I got it working in a minimal case, maybe you could take a look at what I did:
SConstruct:
env = Environment()
from ExtraModule import generate
generate( env )
src = Dir( 'src' )
build = Dir( 'build' )
env.CustomCopy( target = build.File( 'someFile.txt' ),
source = src.File( 'someFile.txt' ) )
ExtraModule.py:
from SCons.Defaults import Copy
import SCons.Builder
def customAction( target, source, env, for_signature ):
return [Copy( str(target[0]), str(source[0]) )]
def generate( env ):
customActionBuilder = SCons.Builder.Builder( generator = customAction )
env.Append( BUILDERS = {'CustomCopy': customActionBuilder} )
obviously, thereâs a file called âsomeFile.txtâ in the src directory. Again, Iâm using SCons 3.0.0, Python 2.7

I tried both solutions but still no luck. It appears that scons does not like the Copy inside the Command builder :
env.Command(target = tgtCpp + tgtH + ccpp,
source = idlFile,
action = [Copy(os.path.join(env['LOCALROOT'], variantDirOutput, idlFile), idlFile),
'idlpp -S -l cpp -d ' + variantDirOutput + ' $SOURCE'])
I am am calling directly
Copy(os.path.join(env['LOCALROOT'], str(env.Dir('.').path), 'MaxSim.idl'), Glob('*.idl')[0])
scons is OK

The SCons Copy() action factory is in SCons/Defaults.py, defined on line 272. I think you just need to import it from there.
(make sure SCons-3.0.0 is in your PYTHONPATH)
From SCons.Defaults import Copy
And you should be able to use it.
If that doesnât work, try importing the copy_func function from the same place and building Copy() from it, just copy-paste the four lines starting from ln. 272 of Defaults.py into the top of your module
Iâm using SCons 3.0.0 (if the directory didnât make it obvious), but the solution should be similar in other versions.
Hope this helps

Subject: Re: [Scons-users] Is it possible to use Copy Action Functions outside of SConscript?
It is screwy I agree with you :)
We have two different version of open splice, one on windows and one on linux.
When scons invoke
'idlpp -S -l cpp -d ' + variantDirOutput + ' $SOURCE'
on windows, there is no problem, it works
When scons invoke the same command on linux, I get the following error :
idlpp -S -l cpp -d build/debug/fwk/dds_model fwk/dds_model/MaxSim.idl
"build/debug/fwk/dds_model/MaxSimDcps.idl", line 7: can't find include file MaxSim.idl
As you can see the opensplice version of linux doesn't like the variantdir, he is not aware of MaxSim.idl, located in src dir. This is the reason why I am trying to copy the source MaxSim.idl to the variant dir.
Now, this bring back the question of duplicate=0. Yes, when I am calling my SConscript, I am giving duplicate=0. In this unique case, duplicate=1 should work I guess, but it is unfortunately not a solution in our current architecture. We have a top down approach where all SConscript are blindly called from the SConstruct with duplicate=0 . SConstruct has no clues which env is needed, he gives a class containing multiple env and SConscript takes the decision which env to take. All decisional stuff are inside SConscript
This serve us well so far. We just migrated a project containing almost 600 make files. That is the only case were duplicate=1 would be needed. So, you have the full context of my screwy fix =)

Why are you building up the target file path?
Are you using duplicate=0?
Looks like you're trying to copy the source file to the variant dir, and then calling idlpp on the source?
Why did you want add Copy in the first place?

I really think it is related with the fact that def compile_idl_files(env): function is outside of my SConscript.

My SConscript contains the following code :

In order to make my SConscript cleaner, I wanted to move this line into a
pseudo-builder, in an utility file.
Then, when I am calling this line :
Execute(Copy(os.path.join(env['LOCALROOT'], variantDirOutput, str(idlFile)),
str(idlFile)))
from my utility function, I have error:
NameError: global name 'Execute' is not defined
I understood that because I am outside of the SConscript context, Execute is
not recognized anymore. I then added my env, like that :
env.Execute(Copy(os.path.join(env['LOCALROOT'], variantDirOutput,
str(idlFile)), str(idlFile)))
Now, Execute is recognized, but Copy is not. If I try to add env to the
Copy function (env.Copy()), I now have this error : warning: The env.Copy()
method is deprecated;
I understand the env.Copy() is depracated, but is it possible to use Copy
action outside the SConscript the same way I did for env.Execute?
Thx
