Re: using depends properly

Greetings,

something I don't get, you've stated I can use env1.Foo('$O/%s'%d), prev)

but the %d is outside of the quotes and the brackets are unbalaced

I'm trying to understand the logic behind this example.

I'm using abspath as a habit to be as much as accurate as possible, if it doesn't matter much I'll drop it.

my main goal is to depend creation of specific files in order to control the build flow.

as stated in my previous mail, I was able to do so by using the actual targets and not the scons files.

Thanks,

Dagg

There is really no SConscript object, though there is a File Node..

Honestly your simple example is pretty confusing.

Why not just explain what you are trying to do?

When I see things like this:

target = env1.Foo(File(env1.subst('$O') + '/' + d).abspath, prev)

I know there's a bunch you're still not getting.

target = env1.Foo('$O/%s'%d), prev)

Is sufficient. SCons will drop the abspath and not use it.

As far as I can tell you want to build a bunch of objects and build up a list of those objects to use somewhere?

Do you want the target of this:

env2.Command('foo.out', '/dev/null', "echo this should be printed after all the sleep and touch ends")

To depend on that list of objects?

to answer myself, I cannot depend on a sconscript object, only on a obje within the file.

let see what I can do with my original project.

Greetings,

here is the example: https://github.com/daggs1/test_scons_deps

the reason I'm using an global list is because in the bigger project, there are 3 different lists which affects different scons files and the list that populates it (a,b,c,d) can be distribued to any of the lists.

if the proper way is to return the list from the scons, then I'll try that (assuming there is no issue in returning three lists from a scons file)

Thanks,

Dagg.

look at scons --tree=all

Greetings,

scons_instance gets executed before any of the entries in the list are executed. as it depends on them, it fails.

I'll try to devise a small project to reproduce it, will update when I can.

Thanks,

You've failed to tell us what's happening.

Can you provide a small example so others can try to reproduce it?

Greetings,

I have a question on how to use the depends call properly.

I have a folder with sconscript file in it which calls a builder on various inputs.

for each input, I save the result of that builder in a appropriate list in a global var.

after that, I call another sconsript file and declares this: env.Depends(scons_instance, list from global var)

if I print that list, I see the targets I've saved.

but I'd expect that all the builders will be executed first and only then scons_instance will get created.

am I using the depends call wrong?

how can I fix it?

Thanks,

Dagg.
